My M17 boom extrusion is 93" (7' 9"). This is just the aluminum extrusion. Add 1/4" at clew (aft) end for cover plate casting that closes off that end. Gooseneck adds 2 1/2" on the forward end (from end of extrusion to back face of piece that goes into mast track - yes I have a sliding gooseneck). So total length installed would be just about 96" (8') from back edge of mast to aft end of boom. As far as I know it's the original boom (#38, 1974). Can't prove that it is; have no reason to believe it isn't. cheers, John S. On 04/07/2018 01:12 PM, Dave Scobie wrote:
Boom is likely about 8'3". I'll measure mine when I go to the boat tomorrow or Monday.
Does your boat have a sliding gooseneck?

More fun, and more questions... I've got 3 booms, and no factory specs. Anybody have any boom info? I'm going to be ordering a new main, and since I don't have the original, I need to figure out which boom I have (none are likely the original boom) will be the best choice. The most important measurement would be the distance between the tack and clew pins at maximum outhaul.
