Un-step every season
I have the mast unstepped every season and pay to stow the mast in-doors. Why? Well, from what I've read, concurrent with what my surveyor said, and the yard people agreed...freeze/thaw is the problem. Water will sooner or later find it's way into vital rigging areas and weaken the rigging by way of the freeze/thaw effect. The arguement is that by leaving the mast up and the rigging exposed to weather during winter months, the lifespan of the rigging is adversely affected. Is it true? I can't say. Do I want to hurry along the demi$e of the rigging? No. This past winter I would say slightly more than half of the sailboats in the marina yard were un-stepped. The previous owner of my boat did not subscribe to the annual unstepping theory, and judging from the shape of the various attachements/lights and so forth on my mast, I would guess it spent many a winter season in place. I have not read any so-called pundit claiming that leaving the mast stepped during winter would damage the mast itself. It does, however, make sense that anywhere water can pool and freeze, that potential damage can result. Otherwise, why would we drain our fresh water systems and fill with anti-freeze during the winter?Mike
