Mast raising system
On the 87-89 boats the mast raising pole is attached to the mast a few inches above the deck and the pole had to be about 90 degrees to the mast. This arangement is shown in the picture. On later boats he improved it by making the fitting that is bolted to the deck with two sets of holes. With two sets of holes (one set at the rear for the mast pivot and one set at the front for the pole) the pole could be pivoted against the mast and stored there when the mast is up.
The next detail is of the end of the pole. The boats made from 87-89 had a metal plate permanently inserted into the jib stay. This plate would fit into a slot in the end of the pole and bolted there. There was also a hole for the block and tackle to attach to. Later boats had two eye straps fastened to the pole. The jib halyard fastened to one eye and the block and tackle fastened to the other. This arangement worked well.
The last part of the equipment was a block and tackle. This was fastened to the metal plate in the stay and the rear hole in the front chainplate. This gave a four to one purchase which made it easy to raise the mast. This picture has the location of the block and tackle reversed. the bolck and tackle attaches to the lower hole and the stay attaches to the upper hole.
The last picture shows the block and tackle after the mast is raised and the jib stay attached.
