Wing Span
Jim That dimension is 24.00 inches. Steping the mast is a bit tricky, are you going to do by hand or will there be facilities available to lift it in place. Alos I have a Z Spar rig, I think there were Seldons used as well and I don't know about those. If you have a crane or jib boom and you have a Z Spar, its not to bad. The mast steps on a plate attached to the deck which has bosses about 1.50 inches high that fit the inside of the mast's cross section. If you have to step it by hand you will need to fit a mast tabernacle or a mast hinge to the base. These are both available through Dwyer Aluminum mast co. 2 Commerce Drive North Branford, CT 06471(203) 484-0419 May have changed to area code 860 by now. They won't have parts made just for your spar but I think they can fix you up. I suggest you get their catalog and look through it then call them.Hope this helpsEric
