There was far more than two feet of mast above the throat. The block for the throat halyard was not at the mast head. There are still several feet above this block, IIRC. The luff on his mainsail is significantly longer than the one shown on John's picture. That's a wicked cute boat, BTW.
Perhaps it's just the marconi rig in me that made it so hard to swallow. We were able to make a nice sail shape, but I felt as though the boom could have been higher off the cabin top (12") and I really wanted to reach for those upper winds...
