Winter temps are usually pretty mild.  Haven't noticed any cracking or
heaving during the winter (except when tax bill arrives).  The floor is
smooth concrete (no scoring or perimeter trough, unfortunately - that's what
it needs), the holes in the slab (directly down to a sand base) supposedly
let the wind blown water drain out.  That's OK, but the too-slight slope of
the floor requires the water to be drawn down through surface tension (!),
since the holes are only every eight feet or so.

The whole arrangement is a stupid idea, which more holes would only slightly
improve.  But better than an air strike.  We are, of course, waiting for a
hurricane, but unlikely to lift up 30 x 40 slab and deposit it in Cape Cod,
where Derek could fix it.  Even then, how could he bring it back?  (Ken, how
big is that boat?)

Sign me,
Just bought a 16' O'Day with a DePersia self-bailer which lets water in, but
not out!!
