I have asked a few questions recently about replacing my rudder and tiller
on my Potter 15.
For the moment I have found a piece of oak where the grain has the same
curves as the old laminated/delaminated tiller. Used it today; worked fine
and looks good to me. If it doesn't warp I am all set; if it does, I will
try my hand at laminating.
I made a rudder cheek out of marine fir with spar varnish to replace the one
that has delaminated. It is just to get me through the season; over the
winter I will make something more permanent.

Is there anything inherently wrong with making a solid rudder, possibly
covered with fiberglass? I keep my boat moored in deep water and never sail
in shallow water. I have never actually had a reason to bent it, and don't
expect to. It seems to me that a solid rudder will be alot more durable
than anything that can be made that bends (except for the plastic/aluminum
ones they have now; but I can't make one of those...).

Am I overlooking something?
