the numbers from my M17, #375 ('83 model) - boom is 7'9-1/4". the gooseneck and aft boom fittings add 3/8" each. the gooseneck adds another 1 5/8". The outhaul block is at the aft end, so the line is turning just at the end of the boom, on the boom's port side. :: Dave Scobie :: M17 #375 SWEET PEA - https://m17-375.com/ <http://www.m17-375.webs.com> :: Truck camper - https://truckpopupcamper.wordpress.com/ :: Ramblings - https://scoobsramblings.wordpress.com/ :: former M15 owner #288 - http://www.freewebs.com/m15-name-scred On Mon, Apr 9, 2018 at 6:13 AM, Mike Barnett <claritysailingadventures@ yahoo.com> wrote:
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.

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.
