creating a tabernacle from a keel stepped mast - SailNet Community Mast sections as cantilevers and deck partners are not strong enough to resist the high bending loads anf thrust from a large mast pushing forward as it is being lowered Eliminating the portion of the mast cantilevered above the deck keeps the mast base and king post largely in shear and axial loading, and reduces the thrust resisted by the deck

repairing cracked mast with welding | SailNet Community The mast is a proctor, which is 47' and only 6"x4" and has a good deal of flex Even with running backs secured, there is flex to some degree through the entire mast, and especially above the running backs while sailing hard to weather The mast is ~ 1 8" thick, and the plate is a good 1 16 thicker than the mast walls

Stepping mast single handed - SailNet Community The mast foot has a pin that goes through the mast step base and then, once the pin is in place, they haul on the boom vang to raise the mast It works pretty well and could be done by a single person, but generally they have two people doing it Do you know where I can buy an A-frame setup or plans to make one
taking the mast down HELP - SailNet Community The mast on a 34' boat is awfully large to be using a gin pole setup Are you sure the hinge on the bottom of the mast is designed for that The forces exterted on that kind of hinge are tremendous, and if it isn't designed for that, someone could easily get mauled if it lets go
