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.
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? :: Dave Scobie On Sat, Apr 7, 2018, 1:50 PM Mike Barnett via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:

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:

7'9" IS CORRECT PER MY MEMORY.

All three of the booms I have available have sliding goosenecks. I think I'm going to use the boom originally off my 18' Sailbird trimaran, as it's in the best shape, has an outhaul car, and is already set up for reefing. I'll just need to move the mainsheet becket to a mid-boom location.
