That's a good point Thomas. That form does look like it needs a little more bite near the keel stringer. I think I got
that treatment from staring at this too long:

But I notice that in most of the wooden frame pics on yostwerks.com, the keel is treated more like what you are
recommending. The upper span may have a similar problem, not from water pressure, but just alignment, though
it's a little hard to judge for sure just looking at the frame, as the stringers, keel and chines stick out beyond the frame
about a quarter inch.

I'll check those all more carefully though. Easy enough to round those over a little more.

thanks,
