The end of the year is drawing very near and it’s time to finish up the Dana build. All of the deck work is done at this point, and it’s time to mount the sails. I’m beginning by finishing the booms and gaffs. The booms are the spars that secures the foot of the sail. The gaff is the spar that secures the top or head of the sail.
The booms have to have a single block attached to each, so that the line that controls the angle of the sail to the wind, the sheet, can run through it and through a sheet block attached at the deck. Meanwhile, the gaffs need a length of line with both ends attached to it. One end is attached near the end of the gaff, and the other end is attached about 1/3 of the way down the length of the gaff. Both booms and gaffs will need a small eyebolt attached near the jaws.
Before going on, I figured some people may need a bit of help with the nomenclature. Not wanting to post any more copyrighted material than necessary, I drew up a quick and simple diagram.
