[Rhodes22-list] Sailing - Highly Technical Question

[Wally Buck]

Brad,

I think I caught a whiff of your boat last weekend. We had strong breeze 
from the west. :-)

You could change the name of your boat to Passing Wind. Come on man, pump 
that thing out once in a while.

My marina has free pump out with slip.

Wally
