I've owned quite a few kayaks, both SOT and SINK varieties, including a Tarpon 100 in rotomolded plastic. I'm a big fan of the Tarpons in general. This UltraLite version I thought was GREAT as I was carrying it. SOTs are pretty heavy usually but this was SO LIGHTWEIGHT, I loved it... until I got it on the water for its maiden voyage. Rode low in the water... lower than my Tarpon 100 so I knew something was wrong. Then it started feeling downright unstable. Well, turns out that's because it was taking on massive amounts of water, apparently through leaks where the scupper holes meet the body of the kayak. Long story here... WS was very willing to repair it (kudos to them) but I was unable to get it to them. So I had to improvise. I ended up getting some clear waterproof caulk and spreading it with my finger around all the areas where the scupper holes meet the body of the kayak. So far that seems to be working. I've only had it out once since I made my makeshift repairs but it seemed to ride significantly higher and I didn't get more than a few drops of water inside. So I'm going to call that a success. Bottom line, I like this boat a lot but you may need to be aware of it possibly taking on water and you may need to solve it yourself if it's out of warranty. (Again, not WS's fault - they were willing to repair.)
