Looks like the keel could use some filling and fairing. That would
help your windward performance quite a bit.

Has their been a major repair made to the starboard top sides forward
of the beam?




Good eyes. The keel, being cast iron suffers from some pitting. I could fair
it with epoxy but then I look at pictures of whale appendages and see
barnacles and stuff growing there and it doesn't seem to slow them down very
much so I don't worry about it on a cruiser that seems to have no problems
reaching hull speed in moderate winds. She goes to weather surprisingly well
for a shoal draft boat. It's the modified Schell keel design that's got a
decent lift/drag ratio considering the short span.

No major repair on the starboard topsides. What you are probably seeing is
the effects of the two-part, closed-cell, urethane foam I poured in between
the component and the hull. The component is the inner hull piece that is
molded to the hull for strength and contains stringers, vertical surfaces
for the furniture, lockers, sole, etc. That foam is tricky stuff. It goes
off fast and expands about fifteen times in volume. Before I got the right
knack of pouring it in very small batches in the enclosed spaces after
hole-sawing about a two-inch hole in the horizontal surfaces to access the
closed spaces between hull and component, I poured a little too much at a
time and it had a tendency to somewhat bulge the larger, unsupported by
stringer spaces on the hull. But, the trade-off is a positive flotation
yacht.
