My boat also takes 2 - my wife & myself, for floating picnics on the waterways and rivers of Britain. I did have some problems with air leakage, but I found Pakboats Alv Elvestad very helpful in sorting out problems. Recently I undertook a 2-day marathon, a report of which, with pics, can be seen on www.truman-enterprise.org.uk. Now I'm getting on in years, I shall have to switch to canoes, but I can thoroughly recommend the Puffins - they are great on price, weight and usability
I don't think that there is another 14 foot kayak or canoe (in any material) that is as light as this and it is really amazing to load it on my rack after struggling with 65 pound sea kayak hulls. It is just in a whole different league when it comes to weight.
As far as paddling goes, it doesn't track very well and isn't very fast compared to a 14 foot hardshell boat. It's really for rec paddling for two people who want to travel with their boat in a duffle bag. I set it up as a single and since I'm 6'4 and 220 pounds, it doesn't seem at all large for me. The stock inflatable seats are comfortable, however they have a fairly low back.
If you are looking for a sleek, shapely boat, this isn't it, as the hull is a bit lumpy to my eye when the inflatable side tubes are pressurized. The engineering of the boat is clever and the quality of the fit and finish is good, although it isn't a Feathercraft in that regard. The bottom material looks to be very rugged and can probably stand a lot of abuse. The topsides are a thinner material that helps keep the weight down.
Overall, this boat does what it is advertised to do and does it well at a price that's competitive with rotomolded hulls of the same size. You can't beat the light weight and small storage when folded.
It is a great boat. I bought it for fishing and camping and it’s better than that. I have WS Pungo 120, which is a great boat, but the Puffin II is more fun to paddle, sits higher and is very quick. It does not track as well as a keeled boat, but it paddled very well on Lake Solano below Lake Berryessa and I am looking forward to taking it to the high sierras next week. The boat is so light, I had a 2 pound trout pull me downsteam for about 3 minutes. It was worth the wait. I am planning to buy one of the folding canoes next year. A little money for a lot of fun.
Once I got my boat together and on the water, everything worked fine. It doesn't track as well as my hard shell boats (Wilderness System Pungo and Current Designs Storm), nor is it as fast, but it was still a lot of fun to paddle. And, because it fits in the trunk of the car, and only weighs 26 pounds, I can get it to locations that I wouldn't carry my other boats.
It is not meant for heavy waves. The Puffin II can work for one person or two. There is an optional spray deck ($225), which I didn't choose to buy, so mine actually is open like a canoe, but I still sit on the bottom, on an inflatable seat. It's certainly the most comfortable of my boats.
