Packyaking in Whitianga (NZ)

diver

At a Dive shop in Whitianga on the North Island’s Coromandel peninsula half a day from Auckland, I asked the teenage girl left at the till which way the tidal currents flowed around here. She smiled at me like I was an idiot and explained slowly.
‘Well, when the tide comes in it like, comes towards you, and when it goes out, it sort of goes away.’
Before I got into sea paddling that’s what I would have said, but I explained what I meant, that tidal flows moved to and fro in a given direction along a coast, not just in out, in out, like a Can-Can dancer’s legs At any constriction or headland it’s a good thing to know when planning or timing a paddle. She looked it up on the internet.

‘Anticlockwise.’

‘Thanks.’

Tides apart, did I really think the surging expanse of the Pacific would be calm enough for a humble 10km coastal packayak round the cliffs of Cook Bluff to the famous and much fridge-magneted tourist icon of Cathedral Cove (painting below)? No, but now on my wavelength, Dive Girl went on to offer me tomorrow’s gloomy forecast: 4-metre swells, 35 knot gusts and occasional showers of razor-billed flying fish.
A good day for a cliff walk then. Coming back next evening from Cooks Beach, I  was a little appalled to see Mercury Bay awash with white-capped rollers, as if some tsunami was on the go. Surf’s up, if you have the nerve.
It was right here in 1769 that Captain Cook and his crew – on the hunt for the fabled Terra Australis – first raised the British flag on the New Zealand shore while engaged in observing the transit of Mercury.

Maybe I’d get a chance the day after, my last. But even in the calm morning, the storm’s after-swell was still pounding the cliffs and beaches of Mercury Bay. Who knows how it was at the Cove of Broken Dreams which, they said, was still closed from the land side, anyway.
Luckily, the cliff-rimmed natural harbour of Whitianga was sheltered from all this Pacific aggression. And better still, the tides were ideally timed to be swept into the inlet, before getting spat out on the mid-afternoon ebb like a retching gannet’s breakfast.

Settling up on a grassy strand near the marina, I realised I’d left my pfd at the hostel – this after noting a warning sign advising that all in <6-m long boats required them. Oh well, if spotted hopefully the harbour master will zoom up alongside me on his jet ski and lend me one for the day. As it was, I was heading inland where there’d be no one.
Once tempered up via my hose extension, I scooted over the yacht-clogged harbour mouth, ferrying across the strong current filling the shallow inlet, tilting marker buoys as it went. I was told later that, partly as a result of dredging a channel for marina access, that Whitianga’s natural harbour was fastest flowing in New Zealand.

On the west side, under a wave-carved overhang (left) I hopped out to temper the MRS again. I like an inflatable as firm as possible but am finding, perhaps due to its larger than normal volume for a non-pump inflatable, that the S1 commonly needs a second pump up a few minutes in.
I’m now wondering if something about half the size or volume of my 600-g K-Pump Mini would be handy to get the Nomad up to operating pressure in one go. This eBay pump (right) cost me just 3 quid posted and is actually similar to the mini pump Alpacka initially offered with their $2000 Alpackalypse. With a pump like this, after high-volume air-bagging, you could judiciously pump to a highish pressure on the shore – assuming the cheapo eBay pump can hack it. Yes, a pump’s another thing to carry/lose and the comparatively bulky K-Pump will do the job in a few short strokes. But unlike a paddle, it’s not ‘mission critical’, as they say in the movies.

Fitting a PRV and being able to pump away until the PRV purged (as I do with my Seawave IK) would be even easier, because you could also happily leave the boat out on a hot beach without fear of it exploding into a thousand ribbons of ruptured TPU. PRVs are unknown on packrafts so maybe I’m over-thinking it, but double-tempering is a bit of a faff even if, as humans go, I have a good pair of nicotine-free lungs.

Anyway, I padded southwards, weaving among the lifeless yachts and cruisers, reminding me of our Hayling Island paddle last summer. Let me tell you, in this world there are a lot of massively under-used boats bobbing around and gathering algae.
Once past a sinister big black tug, the bay opened out and I was in the clear. Nearby, alongside a jetty below a cliff leading to a dwelling hidden in the bush, I spotted this pioneering-era carving.

Beyond here the shore looked oddly mangrovey and inaccessible. Mangroves this far south at nearly 37°? I’d only ever seen then around Darwin where I’d once eaten a so-called oolie worm which feeds in their trunks. Sure enough, turns out hereabouts is the southermost extent of mangroves.
I’m not so keen on this sort of drab coastline, but live and let alternative lifeforms live, I suppose. In fact it was fun to probe the passages below the shady groves as it was due to reach 30°C today.

It took a bit more idle nosing about before I finally located the channel leading southeast to the two small rivers which fed the harbour inlet. The channel narrowed as the supposedly slack tide swept me into the tangled maze of salt-loving woodland. Curving left and right, south and east, as the scaly boughs closed in, it occurred to me that this far down in the bay wouldn’t be a great place to get lost and then stranded in thigh-deep, oolie-ridden silt for the next few hours. Who knows how quick the tide turns. Anticipating this, I’d clocked a hilltop landmark over on the western hills to help orientate myself, then pushed on in as far as I dared, getting maybe 500m from shore before spinning around into the still-rising tide and scuttling back out into the open.

The tide really ought to have turned by now, carrying me back the way I’d come, but the forecast nor’westerly was on time and in my face. Luckily the Nomad’s generous stub nose stopped me making a mockery of the harbour’s 5-knot limit so it was a long hour’s slog back to the harbour mouth, bent against the breeze and slapping waves. A similarly windy afternoon on the Wairoa River a few days back must have got me into paddling shape, so the effort was all put down to good exercise.
Once past the marina, I’d hoped to slip below the jetty, under the harbour master’s cabin and out into Mercury Bay itself. Maybe cruise below Shakespeare Cliffs and then land on Buffalo Beach, like a proper Pacific navigator. But it was not to be. Chances are I’d have just embarrassed myself, tumbling through the surf and into the shore fishermen’s barbed hooks.

My time was up in NZ. Next day, rolling my cleverly adapted UDB (more below) to the bus stop, all was as calm as a kiwi’s cozy nest. I was reminded how sea kayakers must feel when they haul all the way up to the Summer Isles to be met by tent-bothering gales, only to find great conditions as they pack up.
It’ll be there next time and for sure the east side of the Coromandel looks like the fantastic place for some fabulous sea paddling. The beachside hostel I stayed at laid on hefty old SoTs for free and there were plenty of kayak touring outfits in town and around. Give it a go if you ever find yourself down here.

For this trip moving from airport to airport and in a bid to spare my creaking back, I mated my trusty Watershed UDB to a chopped-down lightweight folding trolley I’ve used on previous packboating trips. With chunky zip ties and a strap, the shortened frame fitted securely to the rugged UDB’s back harness tabs.
My load was way under the airline limit, but the thinking was that, once packboating my planned river for a few days, the UDB and small trolley would still be compact, compared to a regular wheeled travel bag.
It was all a way of stopping myself buying the painfully pricey but actually only 500g heavier Ortlieb Duffle RS 140 I’ve been eyeing up. Fitted with an IP67 TiZip (not as good as the UDB’s brass drysuit zip), it’s the biggest one they do, so ought to take my Seawave IK and gear. Lacking a backbone frame of Ort’s RG duffles,
the 140 actually rolls up even smaller (right) than my DIY contraption.
A handy side benefit (which might also apply to the airtight Ortlieb), was that being able to inflate my UDB into a rigid airtight sausage made it easier to wheel around (but not as comfy as a full-framed wheel bag). I got some odd looks giving my bag a blow job by the arrivals luggage carousel, because at departure check-in I had to tug the zip open a bit to ensure it would air-off safely at 32,000 feet.
In my hand I carried my nifty Ortlieb 30-L Travel Zip.

Pumps for inflatable kayaks and packrafts

Tested: Flextailgear rechargeable packraft pump

Your inflatable packboat needs a pump to take form as well as to top-up once on the water. These functions may be best performed by two different pumps. It seems the era of the folding bellows footpump (left) is over and even low-pressure IKs now come with some sort of barrel pump.

A plastic-bodied barrel or ‘stirrup’ pump is light but bulky so not something you’d want to tour with. They’re usually used for pumping up high volume/low pressure things like whitewater rafts, lots of IKs or kite wings. Some pump on both up and down strokes to fill your boat faster, but as you reach higher pressures they automatically or manually switch to downstroke-only inflation to reduce the effort. They work best on flat, firm ground where you can stand on the stirrup plates and get stuck in. The excellent Bravo 4 RED Kite pump below (newer ones are blue) is still well under £20 and will pump up an IK in 5 minutes.

sw05

I got a Bravo 6 with my Seawave once but found it hard work – who knows why. The cheaper Bravo 4 does claim to be an ‘R.E.D’ (‘reduced effort device’) and I can confirm this isn’t some gimmicky acronym. The other port on the Bravo’s handle can be used to suck air from an IK so it rolls up good and flat; you can see creases forming in the hull as you suck it down.

I left my Bravo 4 RED at home one time so bought a Sevylor RB2500G barrel pump (below left) for a tenner. Same size as the Bravo barrels, it did OK for the awkward topping-up of my Semperit’s lilo plugs. It came with push-fit, lilo-plug and bayonet adaptors and sucked as well as pumps. But pumping up my Seawave from flat was exhausting towards the end: I actually got out of breath and had to rest! Morale of this fascinating anecdote: get a Bravo 4 RED and the right adaptor for your boat.

Not all barrels have a built-in pressure gauge which is obviously dead handy in getting the right pressure without needing to faff about with a separate manometer (see below). It’s worth an extra tenner to get a built-in gauge, especially with DS boats. Or fit an inline adapter manometre: see below.

kpump200

The K-Pump Mini (above right) is a handy top-up pump or compact 600-g travel pump. It took 15 minutes to fully inflate up my 14-foot Seawave; the push-fit nozzle works on any IK with one-way spring valves. You have to press and hold the nozzle against the valve. Using it a lot one time, I got the feeling it might break something or wear out the seal (which needs regreasing once in a while). I’ve also used the K-Pump to top up my Nomad S1 packraft which was too big and long to inflate firmly with just its airbag. Fuller review of the K-Pump Mini here. They’re hard to find in the UK, the very long, and slim US-made K-Pump 200 (above right) may also be suited to higher-pressure dropstitch applications.

Packraft mini-pump for topping up IKs

Another idea from Seawave-user Jason, is adapting a packraft mini-pump (left) for topping up. It may take a while but he says it’ll reach 4.5psi eventually. Less bulky and much cheaper than a K-Pump, they’re actually for footballs and the like, so you can find them on eBay for a tenner.

Left, the Bestway Air Hammer is an ‘upside-down’ barrel pump which comes in three sizes and costs from just £6 on eBay. If you don’t want to paddle with your full-size barrel pump, the smallest Air Hammer could work as a compact top-up pump like the K-Pump, but a tenth of the price. The one on the left came with a ROBfin and was rated at 4psi.

High-pressure pumps

More and more IKs now feature super-rigid, high-pressure dropstitch hulls – either just floors or the entire hull which runs 2–5 times higher pressures than regular IKs. Your old Bravo footpump will blow its brains out trying to reach a typical 7-10psi.
Barrel pumps with long, slim bodies, as opposed to the shorter, stockier examples above, put out less volume (DS IKs have less volume anyway) but can more easily attain higher pressures. It’s something to do with the ø of the pump face x the stroke. You don’t necessarily need a super high-pressure iSup board pump.

Left: Bravo Alu RED from £16 • Middle: Bravo 110 >£40 • Right Itiwit (Decathlon) £20

Some of these pumps may be double action. At a certain psi they become single action (downstroke only). I believe the Bravo Alu 4 RED (0.8 bar) works like that. Or they have a switch to do the same and help attain higher pressures. It works. Whatever pump you get for your DS IK, make sure it is rated to comfortably exceed your DS boat’s pressure rating.

What I call ‘raft’ valves

Bayonet nozzles for ‘raft’ valves.
Who would have thought there’s something to be said about bayonet nozzles? Well there is. There are two types: plain (below right, Gumotex) and crossbar-peg or detent (left, Bravo). Both need soft spacer washers to fit snugly against your boat’s raft valve, but the small peg inside the green one will press open your valve stem as you connect it.

You will notice a similar peg on car tyre inflation hoses and also on a hand manometer (below). A manometer can’t get a pressure reading without this peg partially opening the valve as you push it on. A nozzle with a peg/detent means that:
a: you’re not pushing the valve spring open each time you pump (easier pumping) and
b: if your pump has a manometer you will get a constant/live reading as the pressure climbs which is the point of having a built-in manometer. The Bravo one goes from 3 quid; search: ‘Bravo Adjustable HP Valve adapter’.
The only drawback might be that you need to remove a pegged nozzle carefully with Push-Push (Gumotex) valves. Normally a little air escapes as you do this, but if the valve doesn’t spring back closed, air will rush out. Turn slowly then pull away briskly; you’ll get the knack.

Pressure gauge (manometer)
Until I got a Grabner which has no PRVs but ran a relatively high, 0.3 bar (4.3 psi), I never bothered with a pressure gauge (manometer, below) and just pumped up by feel. A lot of people do this. Since then, I ran a Gumotex Seawave and fitted PRVs to all chambers. That meant I still didn’t need a pressure gauge to get the right pressure; I simply kept pumping until each PRV hissed: the boat was then at operating pressure. My Seawave 2 was left stock (no side PRVs) so I have got into the habit of keeping a Bravo manometer with the K-Pump Mini and checking the sides at each paddle when I top up. I have checked this manometer against the floor and it measured 0.25bar which matches with the PRV rating, so I think it’s pretty accurate. Try and get a model with a range of no more than 1 bar (as below left) as that is the range you’re working in. At the moment, Sea Mark Nunn sell it in the UK.

With high-pressure DS IKs, you probably want a pressure gauge as the boat will perform best at the right pressure which may be higher than you’re used to.

Add a manometer to a barrel pump
I’ve had a couple of 0.8 bar rated Bravo 4 Alu R.E.D barrel pumps over the years, including with my Zelgear Igla IK to (a typical DS pressure). In the UK they go for under £20 without a gauge – a real bargain for a powerful and smooth acting two-way pump. The next similarly rated Bravo barrel with a gauge is nearly fifty quid. That’s inflation for you.
The good thing is you can now buy the long lost SP90B inline adapters with a manometer in the UK. The manometer screws into the black plastic adapter which has the male and female bayonet fittings to attach to the 3 Alu’s pump hose and the handle.

Packraft Pumps

Packrafts used to be inflated with a featherlight airbag which came with the boat. A nozzle on the bag screws into the boat’s valve and you scoop air into the bag (easier with a breeze) and ‘bear hug’ it to cram the air into the boat. It’s takes about ten scoops to inflate a boat this way, then unscrew the bag nozzle and quickly screw on the valve without losing much air.
Next, you top off by mouth: the firmer the boat the better it rides. In the video below (speeded up x 15) from walking up to a beach with my paddle in my pack, to loading up and paddling away took 8 minutes.

Things have moved on: most packrafts now have one-way Boston valves which makes topping up much easier. And for those who don’t have lungs like Luciano Pavarotti, you can use a light and compact mini handpump (below) to top up and get the boat good and firm.

Firm boats paddle better but like IKs, a packraft that’s been firmly inflated by hot ambient air on land will go soft once cooled in the water and will need more topping up. The pump above has a hose which means with a Boston valve-equipped packraft, you can top-up on the water, if needed. A good packraft should hold air for days at a time, but don’t leave it fully inflated and out of the water in the hot sun. The air inside heats up and expands, pressures rise and the seams will get strained.

A mini handpump is very handy to get a good fill into your packraft. But now there are tiny rechargeable electric pumps which will do the job of the air bag. More here.

Incept K40 Tasman inflatable kayak review

Incept K40 Index Page

What’s in the bag?
The other night I tipped out the contents of the blue bag and unrolled the boat from a factory-packed volume which, like a new Alpacka, it’s never likely to regain (see below in red). It all added up to:

Blue roll top dry bag
Boat with deck lines and all rudder controls/lines
Rudder assembly
Flexible hatch coaming rod
Inflatable seat
Four GRP battens which slip into the deck to give it form
K-Pump in a bag with adaptors and grease
Boat repair kit (glue, a dozen patches and a valve adaptor, see red)
Basic instructions and an NZ leaflet on safe sea kayaking

Dimensions
According to my atomically calibrated measuring instruments, the boat alone weighs 14.8kg + 2.2kg for rudder, seat, repair kit and pump. It’s 4.3m long, 69cm wide and 45cm wide inside (32.6 lb + 4.8 lb; 14′ 1″; 27″; 18″).
The table from this post compares dimensions on similar IKs. At 17kg the K40 actually feels pretty light and as long as it’s empty, not too windy and the path is easy, I can carry the kayak on my head or the back of my shoulders.

What’s not in the bag – a spray deck. You get the impression that it’s a special shape/item and so ought to be included, but I’m told it’s €103 euros for the one Incept recommend. It’s hard to ascertain exactly what you’re buying from the small image buried on their website, but similar skirts go for around half that price in the UK. I bought a nylon cheapie to be getting on with. It’s actually not badly made for 19 quid, with taped seams and a decent coated material; it’s just way too long, so I had to cut it down.

Aa K40 sits a lot higher than a regular hardshell kayak, so I imagine a skirt would only be necessary when it gets really rough (by which time you probably have other issues) or cold, or you confidently expect to be able to extract yourself from capsizing with one smooth swipe of your blade. It would be nice to master a roll, but I suspect that crawling back into a K40 with decks unzipped is less difficult, especially with a paddle float. More on that here.

The hatch is 71cm long, 41cm wide and 186cm circumference (28″ x 16″ x 73″), if that helps you select a spray deck. Although it’s statistically small, I’ve sat in worse and as it’s not rigid, even I can pull my legs up to get out while still seated.

Thigh straps are a €66 option. Fair enough, but my boat has no D-rings (left, Incept’s pic) for the straps, just markings where to fix them. Some boats get patches, some don’t I was informed (probably heat-welded, left).
Otherwise it’s a lot messy work gluing some on (below left), which will either cost you over £50 for four Incept patches sent over from NZ. Or you can spend hours on the internet looking for alternatives. I fretted, thinking I must buy actual Incept ones which are made from the same PVC-urethane material as the hull. As well as clean surfaces and a good roller, on inflatables the adhesive/material combination is critical for a good, permanent seal.

The actual Incept PVC patches cost $NZ12, similar to the UK from places like PolyMarine. Or good old NRS have all sorts of patches here and among other places, they now have an outlet in Ireland (so all import taxes paid (until Brexit happened).

I bought a dozen #2097s (left) which are a bit big at nearly 5″ (120mm) but can be trimmed. NRS said that Aquaseal (aka: Aquasure in Europe) will do the job on PVC-to-PVC as well as anything, but actually one D-ring stuck on with Aquaseal came off three times.
Probably my bad application so eventually I tried the small unbranded tube of Ultraseal 777 which came with the boat’s repair kit. It’s a much thinner and runnier than Aquaseal and smells like classic Bostik, and because it was not ‘filling’ but just adhering, I thought it made a better, more pliant seal and it cured quickly too. I’ll find out for sure how the 777 patches worked in comparison with the Aquaseal.
Unfortunately, though it’s made by Bostik, I couldn’t divine whether 777 has a magical formula that perfectly suits Incepts polyurethane alloy fabric, but in future I’ll clean off with MEK solvent and use Bostik 1782 – the nearest I could guess and found cheap on ebay.
While my back was turned Bostik seem to have diversified into scores of glues from my youth when the classic, pink-tubed all-purpose glue did it all. Now they sell a glue for scores of uses which the cynical consumer can’t help thinking is marketing- rather than function led.

The SeakayakOban test boat I tried had thigh straps – straight, not as comfortable as pre-curved ones I recall having on other IKs.
Pre-curved straps hook better over the knees, so I got a pair for an SoT off amazon for £33 (left). With those brass-plated clippy things they’re heavy, but seeing as they’re so fat they could double up as cushier backpacking straps on a boat-hauling packframe.

One more annoyance: I was expecting to get the Bravo footpump which the shop I bought it from pictured and confirmed by email. I received the better, hard plastic K-Pump after I went out of my way and bought one. This inconsistency with Incept’s info (including images of models with old colour schemes, velcro decks and talk of ’25 D-rings…’ in current brochures) gets frustrating. You get the feeling Incept aren’t focussed on promoting these IKs, as if they’re a sideline to the raft business. But as long as the people on the factory floor with the scissors and heat guns are on the ball, I’m sure I’ll get over it.

Sadly, quality of construction is also inconsistent. Most of the boat is heat-welded but closer inspection revealed a lifted seam at the glued-on rudder patch (below left). The cavity here was an inch deep and took repeated injections of Aquaseal to fill, but I presume this is a patch glued on the hull, otherwise I’d have a pretty flaccid boat by now.
Nearby, a couple of hull seams had also lifted a mil or two (middle pic). It’s hard to think these would have slipped past any inspection (assuming there is one), so I presume they lifted after that point. These are the only manufacturing flaws I’ve spotted on an otherwise clean job. And to be fair the rudder patch glues around
a curve where two other layers meet, so it’s a difficult join. I’ve laddled the whole area with Aquaseal (last pic) and it’s now sealed for good.

Incepts are made from 1100 dtex Polyester fabric coated in a PVC-urethane blend. It’s notably less thick than an old-style Gumotex. Stiffer is harder to glue into tight forms (as proved above) but makes a faster boat on the water. It’s also more awkward to pack, especially when cold. I can’t see me ever rolling it up as compact as the image at the top of the page (see red text , below). I go on further about IK materials here and once, theboatpeople spoke sagely about Incepts, though it’s unclear if they’ve actually seen one in the raw (never stopped me!).

As the enclosed instructions say, the biggest risk to damaging a PVC craft is when a sharp and stiff corner of a rolled up boat scrapes on concrete or tarmac; it grinds off the coating real quick. I must remember never to do that. It’s unlikely that the PVC-U is as durable as synthetic rubbers like Nitrilon or Grabner’s EPDM, but with care, regular rinsing, squirts of 303 and the odd dab of glue, it should last.
In fact the K40 is the only IK I’ve ever punctured: a tiny thorn tip picked up while pumping up on Loch Moidart. The second owner’s similarly punctured the side while pushing past a thorn three on a river, and again at sea later. Knowing all this in retrospect I would say Incept’s choice of fabric for the K40 may not be durable enough, but the only other owner of an older red and yellow boat has had no flats at all. It’;s possible earlier boats used different fabrics.

Out of the bag I pumped it up for the night and fitted and adjusted the rudder which was dead easy. Next morning all was still pleasingly firm, so off to one of the local lochs. Down on a small beach near a road, again I was surprised how effortlessly the K-Pump inflated the K’s three chambers until the PRVs start hissing at 5 psi or 0.34 bar – as high as any non-DS IK.
I like the idea that on the water you’re able to top up the pump from inside the cockpit as all the valves are located accessibly by your lap, though over the course of that warm day – leaving it in the sun here, there and on the car’s roof – it wasn’t necessary. And I sure like the fact that the Halkey Roberts’ valve caps (left) twist off easily and back on securely, unlike my old Sunny’s horribly stiff and awkward items which never relented in all years or use.

Packing up a Tasman
As mentioned, the stiff PVC which responds so well on the water makes rolling and packing up a K40 a bit of a challenge, especially if space is important and it’s not warm. After a few weeks of ownership I finally gave it a go. First thing to do is the suck all the air out that you can’t do by just rolling; this is something a K-Pump does not claim to do (despite what you may read), but I’ve only lately discovered a Bravo pump (left) can do once you switch the hose to the other port. With the Halkey valve opened (pressed down) the spring in the Bravo’s bellows sucks stoically until you can hear the PVC creaking. All you have to do then is yank off the push-fit hose and close the valve quick against the boat’s partial vacuum – tricky with fingers; you may need pliers.

The ABS K-Pump is heavier and as bulky as a Bravo footpump, but it’s more robust and for a hand pump is amazingly effortless. The K is the pump to use even if it doesn’t suck, but the boat comes with a bayonet valve adaptor in the spares kit. Pop that on a short length of hose and you have a manual – or oral – sucking tube to compact the K40 for transit. If this is all TMI, just say ;-).

nk4-car

First impressions on the water were a bit shaky compared to the test day a few weeks back when conditions were about the same, if not even calmer. Maybe because I was alone, ill-dressed for the very cold water, and the valley caught the odd gust off the big mountains. Who knows what was up, but I doddered around like a beginner, then parked up on another beach for a walkabout, and on the way back paddled with the deck unrolled which was fun. This convertible deck arrangement is such a great idea. It’s like owning a brolly or a mac: you don’t always want it but sometimes you need it.

Part of the reason deck-free is possible is that the K uses a removable bendy nylon rod for the hatch rim or coaming (left). Remove the four chunky GRP deck-supporting battens, roll the deck back to the right side and hey presto, the legs can breath, you can get in and out gracefully and maybe even carry a light passenger.
Though thick and strong, the battens don’t seem to have any influence on pushing the boat’s sides out as far as I could tell, it’s more likely a zipped up deck holds the sides in if anything, so inhibiting longitudinal flex of the hull in rough conditions with a heavy paddler.

The rudder mounts easily and looks like a well made unit, though again, I’m no expert. Foot control is off some flaps on an adjustable air bag footrest using string and elastic. Not surprisingly, it’s all a bit mushy, but I don’t think any IK or even any K will have a system as solid as the Amoco Cadiz. It centres naturally and so works fine as a simple straight tracking skeg which is all you want most of the time. For an impression of rudder free paddling, read this.
If you want to slide forward down the boat (perhaps to pull the deck on or have a snooze) you can easily slip your feet under the semi-inflated footrest/rudder pedal air bag. Turning circle on full rudder lock is about 10 metres, same as our Nissan, and I also observed that you can do a 360 in this boat on the spot with 5 back strokes; in other words: less strokes than you’d imagine. Backing up is also easy with the rudder up and the rudder lift line works fine. A rudder of course came into its own to correct tracking when paddling downwind or at 45° to the wind in either direction, though here is where the mushiness was noticeable. A bit more experimentation with the footrest/rudder pedal air bag pressures and seating/footrest positions may tighten things up.
So far the seat is fine and I’ve had no complaints since. It’s light and simple, but made from thick nylon (compared to an Alpacka) with two elbow valves – and it clips out in seconds, just like the modified seat in my old Sunny. But like on my old Alpacka Llama, you sometimes sit on the squashed down backrest when getting in with the deck on, which could be a pain if the situation was choppy or awkward. There is more back support with the deck on I’ve found, as you lean on the back coaming a bit. I’ve also since found even at sea it’s safe and stable to sit sideways on the seat with your feet in the water.

By the time I got back a couple of hours later I was in the mood for more so I strapped the boat onto the car (another great aspect of frameless IKs) and scooted over to the main beach opposite the Summer Isles. That morning there’d been no less than nine cars or vans with kayak racks heading out for the day. Quite right too as it was amazing weather, so much so that the blooming gorse in the hills caught fire. As I came back, the village fire engine dashed past me, trailing cobwebs and heading for the smoke palling over the Assynt to the north.
Out in the bay a pair of late hardshellers were heading out and it seemed a bit less gust prone out in the open water. After dicking about for a bit, I headed across to Tanera Mor island, about two miles across the bay. We look over to Tanera all day from our place, and on many previous occasions in the Sunny I’ve thought about it but never dared. I suspect the relative speed and higher sides of the Incept gave me the edge and the confidence.
In the island’s anchorage, flushed with the success of my monumental traverse from the mainland of Britain, I pulled over by a salmon pen and watched the caged fish flit across the surface, I presume enacting their instinctive upstream spawning surge, but here destined only for the slicer and the smokehouse. On the way back I decided to deck up for no other reason than I could, noting that when fully unzipped, I can just about reach the zip ends fore and aft to pull them closed, as long as I used the fishpen side for stability. Out at sea if it was rough a boat alongside would be needed. I’ve since lengthened the tabs on the zip ends to make them more reachable.
A small island ferry left the nearby jetty at the same time as me, and mid-crossing its parallel wake crept ever closer until at the last minute I panicked a bit and turned into it to be on the safe side. Later, a bigger fishing boat came across my bows leaving a bigger wake which was no bother taken side on. I’ve since found the K40 is fine in side waves that can make a slinky hardshell a little nervous.
No GPS but I timed myself; 25 mins to cover 2 miles which were a bit choppier than on the way out. That’s 7.2kph or 4.5mph or 3.9 knots if you must. Not bad at all and it all rather neatly validates exactly what I ruminated on earlier about getting a better boat for my time up here: dashing alone across what I would classify as ‘open’ water was one of the main reasons I wanted a faster, decked IK. The Incept has delivered on Day 1.
