Lanaverre 590 Sailboat - Pics 3
Hi Shorty,
I've just figured out the keel / centerboard arrangement, with some weight down low in the centerboard for added stability. The ballast displacement ratio is 25%. Still don't know how much of that 309 lbs is in the centerboard and how much in the stub keel.
Here are some photos of a rusted centerboard and centerboard raising mechanism diagram http://association590.pagesperso-orange.fr/articleDerive/derive.html
The line from the cockpit winds around an 8" to 10" spool in the cabin
which in turn is attached to a 2" to 3" spool that has the line to the
centerboard. Picture in you mind the gearing on a bicycle. Some
owners have added leverage by running the line through a series of
blocks at the forward end of the centerboard case.
The draft is 20 inches with the centerboard up.
