[Rhodes22-list] hull problems?

[Michael D. Weisner]

Joe,

Bottom paint is designed to become ugly and its purpose is to leave the hull 
when sea creatures attach to it.  If your boat was painted 3 years ago then 
it is time to repaint, especially if it is on the hard most of the time - 
the paint has dried out.  The cracks appear to be at points of stress as 
they are near the trailer bunks, where the paint cannot follow the hull 
movements as the fiberglass flexes.  I would sand, inspect to be sure that 
it is only a crack in the paint, then repaint.

The rusty stuff is known as treasure, common on sailing vessels.  The coin 
is most interesting as I have only found gold doubloons in my boat.  I would 
spend it quickly before it looses any more value.
