Easy on the engineers, Rummie. Some engineers do their best work with rum in
hand.

Ric,
Really? You think that it would go through the centerboard cap?The bottom of
the old style center board is rounded. The odds of taking a perfect direct
hit with no forward motion are so remote I won't take the time to calculate
it. Again, this is a what if scenario without it ever having happened in my
Rhodes life. I have seen a whole lot of other things go wrong while
sailing, but do not try to find a scenario that finds fault with our Rhodes
where one does not exist. Give me a real life experience and we will try to
find a reason for it happening and why and try not to do it again. There is
nothing wrong with either centerboard design in my opinion and most of the
Rhodes nation would agree. Are you an engineer by any chance? I have found
that engineers do not make very good sailors. They tend to over think
everything and forget why they are out sailing in the first place: to drink
alcohol. Massive quantities of alcohol.

Rhodies use GPS and never, ever sail in foggy weather. Blue skies and
