The cool thing about the boat is that it can be customized to fit your needs. I built this one with a hatch up front (it'll hold a BUNCH of stuff) and a space for a milk crate in the rear. It's watertight in the rear (around the crate), and almost watertight up front. I used a small cooler as a backrest, and may even try and add a small sail for those longer trips.
As for performance, it's suprisingly stable; at 6'4 and 260 lbs I was'nt brave enough to try and stand up (it was warm outside, but that water was COLD), but I did move around a bunch and even stood on my knees to test it out. It was faster than I thought it would be (about 4.5 - 5 MPH), and cut through chop (read boat wakes) with no problem. All in all I'd compare it to a WS 140 for stability, and somewhere between a WS 140 and Ride for speed. Its 13' long by 30" wide, and according to my home scales, weighs in at a whopping 42 lbs.
The only negative I could find was that you end up sitting in the water that drips from your paddle. There are no scuppers (you're sitting on the bottom of the boat). This isnt that big of a deal; a big carwash type sponge makes a great bilge pump. Also, the sides are higher (only about 5") than most SOT folks are used to, and this makes your stroke a bit wider than normal. Again, no big deal it just takes some getting used to.
All total I spent about $135, including the cheap jigsaw. If you have tools it can be built for around $100.
If anyone out there has ever thought about building his/her own boat, you might give this one a try. Also, if someone will tell/assist me with posting pics, I'd be happy to let yall see the (almost) finished project.
