Mike: A good number of the M17's have the slot for the gooseneck/sail that low ... it is clear that the slot on my mast was originally higher as you can see where the slot was closed using plyers and the lower one opened. My main has slugs and this orientation required me to push the sail up into the mast when I rig the boat. Talk with Harry at E/P Sailmakers. He knows the boat. using what you have he can confirm the measurements for a boat of your vintage. :: 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 9:09 AM, Mike Barnett < claritysailingadventures@yahoo.com> wrote:
Thanks for the help... knowing where the bottom of your sail track cutout is might help too (it appears my gooseneck will be right under the cutout on my mast).
Given that I'm working with a lot of unknowns, I'm going to get my main made pretty close to the original specs - I can make it work with all the stuff I've got!

Mike:
The sail goes as close to the masthead as I can get it. When I first got the boat I couldn't do this as the halyard had an eye to hold the headboard shackle and the resulting diameter of the line wouldn't fit into the masthead fitting. I cut off the eye and tied the shackle with a bowline.
I can measure where the gooesneck 'floats' next time I'm at the boat.

Dave,
When you hoist your main, how close to the top of your mast would you say the head of the sail is? Trying to figure out the ideal luff measurement for my boat's mainsail (I don't have an original, and I'm questioning the location of the gooseneck/sail slug cutout).

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.

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.
