49752Re: Gypsy won't track
- Jun 7, 2006it seems to me that the solution IS a small skeg just forward of the rudder. This need not
be of large area in that it is so far aft. I wouldn't worry too much about lee helm from a
small increase in lateral plane aft - too many other factors here. In any case plenty of
adjustments could overcome this even if it did occur (which it probably won't).... eg:
rudder is obvious choice if this is left in place while rowing (though that alone would
obviously give the correction in tracking ability you are looking for under oars without the
addition of a skeg), increase mast rake aft ever so slightly, shift a bit of weight aft (things
you might presently be stowing forward), etc. All of these would counter any lee helm...
which again, I would not strongly expect.
I actually believe a small skeg aft could improve Gypsy's utility overall.
As to fastening to 1/4" ply .... after trials with skeg shape and area, epoxy and screw the
skeg to the bottom from above, and then fashion small fillets at the junction of skeg and
bottom on either side. They will improve water flow as well as add the additional strength
that may be desirable.
