[Rhodes22-list] Boom Room Design

Wed Feb 1 19:31:43 EST 2006

Bill,
A boom room without some rigid SS poles or tubes would require significant alternative support to provide the interior space and shape most of us would really want in a cockpit located structure.  If the boom is the prime support for the roof and side curtains, the main could be used only if the poles are disconnected and stowed after using the room each time.  Not really a big deal.
If the boat is sailed only under Genny, the poles do not need to be disconnected, and the boat now has a nice bimini, with or without curtains attached.
If the main is to be used, an additional pole needs to act as a alternative roof peak, parallel with and just below the working boom, providing both a bimini and room with rather simple deployment.  This horizontal pole would need a vertical support from the cockpit deck, probably anchored like the cockpit table. The forward end would sensibly be attached to the back of the mast.
Any thoughts?
