I'm sorry... I was thinking catamaran/trimaran....

On the multis when it gets really tough, the centreboard/boards are
pulled up to save them, allow the boat to be pushed sideways and to
stop it tripping over the boards.


And indeed, I was always told, by my designer among others, that
that is also what should be done in centreboarders in those
conditions.

I read you should only pull the centerboard up in those conditions if
it isn't ballasted or part of the ballest. (ie: Iron centerboard).

OK, I tend to forget the modern trailer sailer--the baots I'm
referring to all run ballast, be it water, lead or concrete,
either inside (fastened) or outside as a shoe or plate on the
haul bottom. The centerboards, bilgeboards or for that matter
leeboards are simply fins: they do not form part of the ballast
other than incidentally (they themselves might be ballasted to
neutral or slightly negative buoyancy, and when extended they do
make a minor contribution to the righting arm--and a tiny
contribution to the capsize side of that equation when up). This
is quite different form trailerables with a hunk of lead on the
bottom of the daggerboard/centerboard, without which the
trailerable wil knock down when breathed at.

So anyone with a centreboard that's also the primary
ballast---what are you doing outside in those conditions????
