Test boat loaned for review by Shipwreck in December 2020

Out of the box

Shipwreck is the latest contender in self-branded full drop-stitch (FDS) IKs customised in China to an importer’s specifications. With the ArrowStream – not a bad name – you get all the kit including two four-part paddles and a two-way barrel pump.
The box it came in weighed a staggering 29.5kg – I could barely get up the stairs; it’s twice the volume of my Seawave 2. But once unwrapped, the whole kit: everything in the bag, weighs 25.4kg.

The bare boat itself is only 17.8kg, and with one seat and footrest, the splash vizors and the skeg comes in at 19.7kg on the water (plus pump and bag) according to my kitchen and suitcase scales. By comparison, had I kept the stock seat and footrest on my Seawave 2, it would have been 17.7 kg on the water, so that’s not as bad as the bulk – about 90cm x 70cm x 35cm boat alone in the bag – might suggest.
According to my tape it’s 431cm long and 83cm wide. That gives it an LxW ratio of 5.19 which, compared to the table here is also pretty good. And don’t forget the maximum width is measured high up on the outward-angled sides; the actual width at the waterline is around 60cm or 23.6 inches – fairly slender by IK standards. More on that later. The big advantage with these slim, 10cm-thick side panels compared to round tubes is loads more space inside. The interior width is 45cm at floor level and 66cm at the top of the sides.

The seats include a hefty 9cm-thick seat base incorporating a firm, 6cm foam block which can be zipped out. I can see that foam feeling a bit hard sat on the hard, 10psi floor after a few hours, but it could be easily replaced with something softer or lower. Or you could even zip an inflatable cushion in there to reduce the packed volume, but it will wobble a bit. The backrest is tall and wide, with loads of tensioning straps to get the position and angle to your liking. You can reposition a solo seat in the middle, a big benefit with any open tandem IK.

The footrests add up to a couple of 4cm ø hard foam tubes. This diametre is too small for a secure foot placement and they squidge once you push on them. For the test I replaced it with a section of 10cm PVC drainpipe. There are two pairs of D-rings on the floor to attach the tube, presumably with the two packing straps supplied. But that means adjustment is only forwards, away from each seat. So if they’re too far away for your feet you’ll need to adjust the seats forward which may not ideal for trim. However, in the tandem video above the attachment D-rings appear to be in the right spot, even if the trim at 2:09 appears a bit front-heavy. For my solo paddle I joined the two straps into a loop (above left) to use the footrest pipe. Pushing off a proper footrest makes sitting more comfortable and less slouchy. The important thing is the D-rings are there.

Flexible plastic splash visors slip under the rims of the short decks, and the slot-in skeg is the usual (for this type of boat) 9-inch monster. There are handles at each end and a pair on the sides.

The supplied mesh-sided backpack is commendably huge: big enough to get everything in. There are cinch-down straps on the sides and the top, and a big zip plus a clear pocket on the front. The mesh sides will help a wet boat air off. But considering the weight it’s carrying, you do wonder if the shoulder straps will survive too much heaving on and off on public transport. I know my Gumotex backpack didn’t, and neither did the similarly huge Kokopelli Moki bag.

The whole assembly of the boat is very clean – that’s the wonder of heat-welding compared to messier rubber gluing. An exception are stray thread ends inside where a tape covers the floor–sides cavity (left). Once inflated I could see no blisters in the DS panels which, with threads every 5mm, adds up to an estimated 4 kilometres of space yarn! Maybe that’s what explains the bulk, but once vacuum sucked down, I don’t think so. It’s more that the stiff but soft-textured PVC can only be loosely folded over, not rolled up. Half the bulk is just air.
The supplied four-part 220cm alloy paddles weigh only 950g and have blade-angle adjustment holes 45° either sides of flat. The blades also have little hooks cut in the sides which are actually quite handy, now I think about it. Assembled, there’s quite a lot of slack in the three joints which will only get worse with use but they’ll certainly get you moving until you decide to upgrade.

Pumping stations
Pumping up the ArrowStream to an indicated 10psi measured by the 1.7-litre barrel pump’s built-in manometer took less than 90 seconds for the floor and a minute for each side. The pressures may be high but there’s much less volume here than a tubed IK. The pump comes with a nifty red cap which you easily unscrew to switch to downward-action-only to help attain higher pressures. I actually managed those times on double action all the way to 10psi. It’s manageable, but others will welcome the lighter pumping option as pumping effort increases. Checking against my accurate Bravo hand manometer, the 10psi figure on the dial was spot on. Good to know.

One good thing about the 64cm tall pump is that, I at least, stoop less compared to my 45cm Bravo. That makes pumping a whole lot more comfortable, though conversely shorter pumpers may find the height awkward. As mentioned here, a barrel pump suited to higher D-S pressures needs to be relatively tall but slim.
The raft valve nozzle on the end of the hose had the bridge inside to press open the inflation valve once clamped on, so as to ease the pumping effort. This also enables sucking the boat down to maximum compactness. I’ve only just realised these nozzle bridges are the key to compact suction packing, as long as you have push-push valves. After shrink-packing, as you quickly remove the nozzle the valve closes and virtually no air in sucked back in.
One thing you don’t get on a self-branded boat like this is a conformity table stating recommended pressures, HIN, payloads, ISO rating, CE stamp and so on. But there’s a one year warranty against manufacturers defects.

On the Water

I’ve been speculating about these boxy, hardshell-stiff full drop-stitchers for years and finally had a chance to try one. I picked a 21km (13 mile) section of the Thames from Shepperton to Richmond with three lock portages on the way.
From where I live it’s an hour and a half by train, then a 20-minute walk to the river: a good test of real-world packboating. All I had to do now was sit back and wait for a sunny, mid-December day. In the end I settled for a dry day and once I got there, it dawned on me I’ve not been to my local train station for 9 months or more (this was Covid Year One). To spare the mesh backpack, I used an old folding trolley. It can hack rough treatment but these days most London stations have lifts, so the whole trip was rather effortless.

A 15-minute walk from Shepperton station, I’d located a perfect put-in off Google maps: a paved dock down a bank tucked between trees and just a foot above the water (left). As so often happens when setting up in the more populated south, a passing chap was curious about the boat. Little do these people know they’ve stumbled upon the UK’s self-styled inflatable guru! A comprehensive exultation of The Packboating Way may have been more than he bargained for.

The planned route broke down as: 4km to Sunbury Lock; about the same to Molesey Lock; another 8 to Teddington and 4 or so to Richmond. As I wrote recently in my IK guidebook: first time in a new boat choose a quiet, safe and easy spot and if in doubt, do the tippy test before you let go of the river bank. Perched on the thick 9cm seatbase, the ArrowStream felt wobbly on its relatively narrow hull that’s about 60cm wide at the waterline where you sit. At a guess my Seawave 2 might be 70cm or less at the water level, but the difference must be that the Seawave sags a bit and leans over onto round side tubes (below right) which vaguely maintain the waterline width; the Shipwreck’s super-stiffness and near-vertical sides are what I’ve decided to call a ‘flowerpot’ profile (below left) which quickly narrows and has less to support it as it leans over.

Had it been a lovely summer’s day in a shallow pool, it would have been interesting to push the tippy test past the limit. And also find out how easy it was to re-enter the ArrowStream from deep water. But it was a cheerless mid-December day on the Thames. I suspect the Shipwreck is more stable than it feels: what they call low primary (upright) stability but good secondary (leaning) stability, though some think latter concept is bollocks; a kayak either feels stable to you or it doesn’t. As for deep-water re-entry, like a canoe, the tall, thin sides may make that tricky, depending on how well you can dolphin-launch yourself up and into the boat without pulling more water in.
Luckily I had the option to zip out the 6cm foam block from the 3cm padded seatbase envelope and sit nearly on the floor. I could try the block later when I was more accustomed to the boat. Sat lower, the boat felt normal. It can be rocked side-to-side more readily than my Seawave and you have to make sure you sit right on the centre line. As others have said it may tip off centre but it won’t go right over, at least on flat water.

On this first stage, in the interests of analytical rigour I planned to use the four-part paddle before switching to my trusty Werner. In fact it worked perfectly well for an alloy straight-shaft. You don’t really notice the slack joints, though the width of the boat’s high sides caused the paddle to brush against them. It was the same with my Werner later, so it might be an idea to tape this area against wear. Sat on the seat foam block or other added padding would get you higher for more paddle side-clearance.
Once I got on the move the biggest problem was as anticipated: the tendency of the ArrowStream to track straight as a streaming arrow. Normal inputs to fine-tune the direction had no effect and progress became an annoying succession of straight lines broken by occasional hard hauling or jamming in a stern rudder/forward pry (it’ll all be in the book!) to get it on track. This was the same issue we had with the Moki a few months back. Is it the stiff DS floor? Is it the huge skeg? The sculpted hard plastic bow and stern prows? Read on, but I got to Sunbury in less than half an hour which was a pretty good 5mph with help from the current.

Here I didn’t think to investigate what had looked on Google like a fish-ladder/mini weir on the left of the lock. I now realise it was a very handy canoe roller ramp: a slopping drop which would have made portaging near effortless. I’ve never seen these before; with a little more excavation they could be made into chutes as found uniquely on the Medway but perhaps the Thames’ current gets too strong for them. Instead, I hauled the kayak up onto the towpath, carried it past the lock and clambered back down a dockside ladder. Grabbing one side-handle, a solo paddler can rest the boat on the hip and carry it a short distance.

Paddling off with the weight (trolley, pump, spare paddle) now in the back and my Werner in hand, progress improved. A favourite paddle of 15 years fits like a well worn pair of boots, except boots would never last that long. I still hadn’t got to grips with steering nuance. There is just no way skipping a few strokes on one side will make any difference: the Arrow Streams full ahead like a rocket sled on rails. Of course, it’s better that way round than the other.
Somewhere downriver a mate who lived nearby was standing by to grab some drone footage, but you’ll see better video at the top of the page. A few stills below.

With half an hour spent chatting or in a holding pattern while the drone buzzed overhead, annoying all in earshot, I wondered if I’d left it too late to get to Richmond before dark. At Molesey Lock I nearly made the same portaging mistake had not a kayaker catching up scooted down the ramp (below). They may not be as much fun as a chute, but with shallow water on either side, you can hop out and portage in a minute, even without using the rollers. It’s probable the day’s three locks (plus Richmond’s tidal barrier, just downstream of town) are the only such roller-ramps on the Thames’ 45 locks.

From here it was an 8-km stretch to Teddington where I thought I might bail if I felt tired. That’s the great thing with a packboat: you can change plans as you go. After passing rows of cute riverside dwellings and many seemingly abandoned boats, from here on the river was less grubby and urbanised as it passed the vast grounds of Henry VIII’s Hampton Court Palace.
Right from the start I’d been surprised at the number and variety of birds on the Thames, not least the hordes of swans (which were protected by ancient royal decree until 1998). I noticed one had a cunning way of fluffing its wings out into a pair of downwind sails to tale advantage of the tailwind.

Like a weary traveller, I came upon a glittering riverside metropolis and for the life of me couldn’t work out where this was. Happy shoppers and joggers where cruising along the waterfront. Cafes, bars and patisseries were making the most of it before Covid restrictions ramped back up in a few days. Was Thames Ditton really like a mini-Manhattan? Or have I been cooped up indoors a little too long.
I asked a passing boatman what was this place of wonder.
“It’s Kingston, mate. Why, wherja think it was?”
I hadn’t the heart to tell him.

As I paddled past, I clocked the distinctive slabby flanks of an Aqua Marina Tomahawk tucked between two raptor-like speed boats. That particular boat was about as good value an FD-S IK as you could buy until this Shipwreck washed up on the ebbing tide.

I drifted under Kingston Bridge which I must have ridden over scores of times in a past life, whereupon the Miracle of Kingston delivered one final benefaction: the setting sun burst out from beneath the carpet of clouds which had smothered the London skies for the past week.
The shock was so great and the light so stunning against the steel-blue clouds, it could not have been a better time for the cold to get to the camera’s battery. I managed to rub it into delivering one last shot of the stately riverside plane trees before it packed up for good.
This illuminated setting invigorated me for the final lap to Teddington Lock and Richmond beyond, but three hours in, the old butt was getting sore. One good thing with the ArrowStream and similar is you can lift yourself up on the hard sides to aire le derriere.
This turned out to be one of the nicest stretches on the Thames I can recall. The riverside sticky-beaking, enigmatic islands and doubtless loads of history if you care to investigate, makes me realise that without its sporty chutes, Kent’s Medway is just another ordinary, agri-saturated Southeastern drain.

Converging on Teddington Lock with a quartet of silver-haired sea kayaking ladies, like a well-conditioned lab rat, I knew the form by now: canoe ramp, river left. Here I decided to remove the skeg. Straight away I set off at a faster paddling rhythm and found the boat much more lively, but in a good way. Yes, small corrections were needed to keep track, but now I was off the monorail and could wander and weave around like a normal IK. I wish I’d done this earlier. As suggested elsewhere; the sweet spot must lie with chopping that dorsal fin down. At the lock I also slipped the seat block back under the seat … for as many nano-seconds it took to realise that was still a bad idea. Something softer but less thick is needed, but watch the IoW video at the bottom of the page to see proof that this IK can be manageable at sea.

The trees of what I thought was Richmond Park (actually the near-contiguous Ham Lands) glowed orangey-red as I cruised below Richmond Hill and under another familiar road bridge to arrive at the ramp where Steve and I had set off for Greenwich nine years ago, just after the last London riots. Lord know there’s plenty more to riot about these days, but now it’s all conducted online which is much more hygienic.
Like Kingston, twilight on Richmond waterside was throbbing with ducks and Christmas revellers. I took my time draining and folding up the boat (chatting IKs with another curious chappy), rather pleased I’d managed the distance in exactly four hours without ending up too knackered. Part of that must be down to a backwind and the Thames’ swift winter current, but most of it’s owed to the Shipwreck ArrowStream, a fast flatwater cruiser whose potential is released once you dial in the right amount of skeg which may be none at all.

Drying
The twin drain plugs at the back worked fairly well on the ramp at Richmond; a pint or two spilled out from the cavity formed between the sides and the floor and which will almost certainly not dry out fully. The mesh-sided backpack helped, but you could tell it would take more to dry the boat off fully prior to long-term storage. In our flat I left it in the warm hallway (with an appropriate warning sign) and gave it what I thought was a final wipe down, but folding it up more water splashed out from somewhere, possibly the hollow prow beaks at either end.
If you have the space the best way would be to lean it inflated on a wall in a warm room (or out in the sunshine), let what’s in there run to one end and deal with it there. If you’re really serious about the side cavities, you might get to them from either end with a hose attached to a hair dryer set on low.
