As of early 2021 it seems WindPaddle.com are no longer in business.
But there are plenty of knock offs around.

I’ve been waiting for the right kind of wind to have a proper go at WindPaddling my MRS Nomad. Sunday was not that day with SW gusts up to 25mph. Yesterday was more like it: direct from the west at 10-15 meant a chance to run down the full length of Loch Ossian with the wind erring towards the road for the walk back or if it all went wrong.
You forget that starting at the upwind end all is relatively smooth and calm, but soon the fetch kicks up and stays that way. Progress gets a bit lively so you need to be on top of things which includes stashing the paddle safely. I found tucking it across the boat under some red sidelines (left) worked well and are more often useful for manhandling the boat. Lunging after a lost paddle would be bad; so would letting go of the sail’s ‘reins’ and having the boat run over it. The sudden drag and deceleration might see the racing boat slew sideways and flip you out. And before you come up for air, your packraft is skimming across the loch like a crisp packet.
I don’t know if gusts vary in direction but you also need to constantly modulate the reins left to right to keep on course. It’s said downwind sails like the WindPaddle have a narrow windspeed window which tops out around 15mph. After that, they start fluttering left to right in an effort to shed the load, as mine did a couple of times. Going out in stronger winds may be too hard to handle or very exciting. As it is, the maximum hull speed of a packraft must be about half that and, just as a cyclist’s energy to overcome wind drag grows exponentially with speed, so to you can only push a paddle boat so far. A packraft is about as hydrodynamic as a training shoe.
With the gloomy skies I was initially a bit nervous. Controlled by the wind and without a paddle in your hands felt disconcerting; a sunny tropical locale would have fixed that I’m sure. As usual with packboat sailing, it’s never just sit back and skim along like yachts seem to do; you have to keep correcting. At nearly 3m with the skeg fitted, the MRS is longish which must help keep it on line. And as mentioned before, with the WindPaddle you can steer at least 30° off the wind.
According to the GPS, 9.3kph (5.8mph) was the peak speed, though most of the time I was zipping along at about 7.5kph. It felt faster as wavelettes broke to either side and occasionally over the bow. With the big Corry paddle, at maximum paddle exertion on flatwater I can hit 6kph for a couple of seconds. So once you relax, sailing can be a fast and energy-saving way of covering distance, and the WP folded up and stashed easily under the DeckPack.
I was expecting to walk back but gave paddling a go and stuck with it, hackling along at 2kph with rests every 10 minutes. Fifteen minutes sailing downwind = a 50-minute paddle back. I still think for the price, weight, bulk and ease of fitting and use, a WindPaddle is a worthwhile packboating accessory.
