Ouch! The club here has two smaller fixed cranes and a "pole cat" - a used utility truck with a boom arm. The smallest fixed crane will do masts easily up to 30 - 32' boats. All are available for free with volunteers operating the pole cat.
For haul out the club hires in two large cranes. So we get the masts unstepped and stored, the cradles brought in by forklift and laid out, the boats hauled, stored over the winter, the boats launched, the masts stepped and cradles stored for $900 on a 30' boat. It is self service for the mast unstepping / stepping and layout on the mast racks, but there always is lots of people to help. I have removed and serviced the original sheaves on my 30-1 twice. I cleaned them up when I went from wire to rope and replaced the Oilite bearings, then replaced the Oilite bearings again two years later. The bearings were crushing a bit and the play allowed some sideways misalignment, ending up in scoring the sides of the sheave and the mast casting. Also lots of friction at high loads. Last year I replaced the two jib sheaves with Acetyl ( Acetal - Delrin ). I found ISOMAT had the correct size and were the two piece design I wanted. So a smaller "donut" goes around the SS shaft. I purchased that undersized and drilled it out to be a press fit on the shaft. The Sheave goes over the donut and uses the increased diameter as a plain bearing. The Acetyl is very hard, in fact rated for use with wire. So far this year, including numerous sail changes at over 20 kts in the LO300, the sheaves have worked very well. Lighter weight, no grease required. Will check them when I pull the mast next month.

Cost me $400 to unstep the mast of my 35, and $800 for my 28 in Annapolis!

I was all worried about that before doing it last spring. It took 10 minutes of taping the rod threads (To mark the turnbuckle position adjustment), 10 minutes for 'Stumpy' to pick it up with the travel lift and set it down on saw horses (So smooth, a complete non-issue) , and 85 bucks for the round trip. Best 85 bucks I ever spent. There are so many other things you can fix, clean, lube, inspect, replace, and improve while you're at it.. -Francois 1990 34+ "Take Five" Lake Lanier, Georgia
