There were two different centerboards for the Rhodes 19. There was a
fiberglass centerboard that weighed 100 pounds less than the
alternative cast iron board. The boats with the fiberglass board have
100 pounds of ballast added to the bilge to compensate. I don't see
any serious problem with keeping one on a mooring. Two people can
unstep the mast and haul the boat out on a trailer without much fuss
in case of a hurricane. Another nice thing about the Rhodes is that
there are thousands of them, and they are still in production. You can
get anything you need for them.

Forwarded this info. Thanks.
