I cut the top of the sheer per plans on one panel and the bottom of
the sheer on an other panel.
I then laid the two panels on top of each other and traced the top
sheer line 3 inches taller on top, forward only. I left the transom
as planned. This makes one panel as the bottom sheer has already been
done. Now just copy this panel to the other.
It does look nattier.

shoes on the bottom. It's plenty stiff and the boat is still light
enough to horse over my head long enough to get it on top of the
pickup. I can't see any reason not to build the power version with a
- I used the 1/4" without regrets. However, I put down a grating on my
boat that lifts out--it's very nice, artistic even, and raises the
center of gravity of stuff in the boat by .5 inch (but has little or no
effect on someone sitting on the thwart).
Setting this in involved epoxying into place a couple of athwartship
runners that did serve to stiffen the hull bottom. Since they are
lighter than another 1/8" plywood, and serve another purpose (holding
the grating in place), I preferred it.
But overbuilding is often a bad idea, and when these pile up and pile up
and pile up--they harm the boat's performance.
Keep in mind that the boat is designed by an experienced boater,
designer, and engineer. He probably already knows better than you do.
