Lowering the mast.
There have been a few references I've seen on the net to lowering/raising the mast on the water. I did see a method of lowering it to the bow so that the boat could pass underneath a bridge. I believed that this method had the sails and boom attached and that the mast was hinged forward with a pulley or block system attached to the backstay and the clew end of the boom.I have also seen a few other handy ideas. One is to use two poles attached at the upper shroud deck fittings. These two poles meet at a point at the forestay (when the mast is up)and attach to the Forestay wire. They help to steady the mast from side to side at a critical time in the lowering process. The forestay wire is also attached to a line and lowered by a person, a block assembly and/or a winch.Also there is a setup available called a mast step which attaches to the stern rudder gudgeons and is a telescoping metal pole with a seat at the top for the mast that helps raise/lower the mast up beyond the most difficult weighty period of the first 8 feet or so. It is available from Catalina Direct for about $150. A resourceful person could also make something very similar out of wood and other parts. When lowering to the stern, remember as advised that the only stays that really need to be removed are the lower forward shrouds and the forestay. Removing any others when dropping may result in a mast overboard. When lowering, make sure that the shrouds don't bind on the deck fittings and bend them or the turnbuckles.
