Fellow Jack Tars, Spirit is a 2007 M17. When I try to raise the mast with the shrouds set two things happen: 1) The section that runs crosswise inside the Dwyer mast hangs up on a bolt that sticks up from the mast step. I have almost eliminated this by making a semi-circular clearance cutout in this section but I still get a snag now and then. 2) Even if the mast clears the bolt I still hit a "bump" right before the mast goes full upright. One of Jerry's recent posts says that this is because the base of the mast isn't properly radiused. Cutting a radius using the distance from the center of the pivot bolt to the base of the mast as a guide makes geometric sense, but it cuts away a LOT of the aft edge of the mast base. I'm wondering if this is going to compromise the mast in some way. Has anyone done this? Jim M-17 "Spirit"
