RedCloud has Steel punching and cement for ballast in her keel now.

Most corrision on steel boats is from the inside out. Some people think
having air flow preserves the hull and use pegboards and stripping and
such for interior bulkheads. I don't believe it, as you know when warm
interior air hits the cold steel it's going to sweat. I have 2 inches
of insulation with to vapor barriers and a foil thermal backing, all
taped and sealed behind the mahogany and fgb. No sweating inside
redcloud except on the overhead escape hatch glass, It drips like a
coffe maker on a cold day and must be cracked open a bit. I disagree
with Doug assertion that a board is only good for round the bouy
racing. He must be thinking of a dagger board not full keel board like
on RedCloud. Infact with the board down rounding the bouys would be
slower. The board all the way down is best to help head futher upwind
and I raise it up to 1/3 down on a downwind run shifting the load aft
like the feather of an arrow keepin her straiter.
