I dropped the mast at the slip w/ the A-frame method, rebuilt the masthead with the Garhauer ball bearing sheaves, drilled out the top of the masthead and the top of the mast cap to run internal halyards. Installed two double exit blocks close to the base. Now I have four halyards, well three with a spare, I installed a rigid vang so no need for the topping lift
Though the mast with all the attachments i.e. shrouds, winches, etc., was much heavier than I expected, the "A" frame worked great, only one guy from the harbor patrol who does not grasp the concept
of physics had a challenge with it. Only problem was the lifting point ( just under the lower shroud
attachments ) was below the center of gravity. This actually worked our in my favor as no lifting or heavy carrying was involved with bringing the mast base forward to the bow pulpit, not much weight was required to hold it down either.

9, 11, and 17 stepped the mast in about an hour last weekend.
