I've been following your posts with interests during my Classic 10 build. Partly through accident, the longitudinal curvature of my boat came out flatter towards the stern than what's shown in the design. Maybe I cut the last station taller. I'm hoping the flatness will spread the pivot point and help restrain the bow rise. I'll find out soon enough when I put the boat in water this weekend. Regarding your suggestion of testing without seats, I thought about that after on one of your previous posts. It sounds a little crazy, but in the end, perhaps a pair of small bean-bag seats would allow the best seating flexibility.
On your immediate problem of the bow rise, which I may also experience, how about attaching some flotation under the stern? The real trick there would be to contour it in close to avoid the drag issue. Some sculpted polyiso rigid foam, which I find accepts acrylic house paint well, might be the answer.
Now, about a different subject, the roving. Seems pointless when the Dacron skin is a stressed member in parallel, so I didn't bother with the Kevlar. If the roving was stiff like wood, it would make sense as a skin reinforcement. But the roving is limp, so no real help there. The real weakness of the design IS the skin as you have experienced first-hand. Someone on the group posted their success with three coats of polyurethane, so I went out and bought two quarts of the waterborne stuff and used an HVLP gun to apply every last drop of it, about six coats. Even so, the skin still seems vulnerable. Maybe the coating will harden up over time to form a stiffer shell, we'll see.
I had originally bought two packages of Dacron thinking I would go with a double layer, but when the time came to cover the boat, the possibility of something going wrong with the heat shrinking of the second layer gave me cold feet.
Thanks for your posts, and best of luck with your Classic 10. I'll let you know how my boat sits after this weekend's test.

I have been rowing my Classic 10 for about 3 weeks now, using it as a yacht tender for my wife and myself. After taking the boat out the first time I found it to be very badly balanced with two people in it; way too low in the stern. I attempted to make a repair by moving the middle seat around 10" forward. This isn't enough, and the boat sits way low in the stern with a 125 pound person in the stern seat and myself, a 165 pound person in the rower's position.
I strongly suggest to anyone building the boat that they use some sort of temporary seats (perhaps wooden boxes or something similar)to check the boat's balance before epoxying in the seats.
I'm also finding the freeboard on the classic 10 a little low (especially with the stern being so close to the water). If I were to build her again I'd add 2 - 3" onto the molds...probably add another stringer. Anyone else finding the same problem?
