Bob, I would suggest a removable jack. The Bulldog line of jacks has a removable model, although I think it is a little oversized for our needs. Other manufacturers may offer something similar. First a trunnion (a small cylinder) is welded to the frame. Then a pin is inserted either through a horizontal or vertical set of holes to secure the jack to the trunnion in either the working or travel position. When the pin is removed the jack may be completely detached from the trailer for launching and retrieval. You may also weld the trunnion to a small steel plate and then bolt the plate to the trailer with U bolts. If you have a galvanized trailer this likely would be a better approach. You would want to paint or powder coat the plate. Or you may decide that living in such a nice sailing location is a small price to pay for buying a jack every two year. steve Steve R. Lexington, KY M-15 #119 ******************************************************** I frequently sail in salt water (SF Bay) and am having trouble with my trailer jack seizing after a season or two. I religiously rinse it after each sail, but I have the impression that rinsing is ineffectual; the sea will always win. I disassembled it and poured penetrating oil on the screw and block and finally freed it; now, what is the best way to clean and preserve the threads. The outer assembly is galvanized, but I can't tell about the threads on the screw, which are covered in grease and rust. Is Navel Jelly the answer, or are there better products on the market? I know Fulton now sell a salt water jack, but I have two of the older models and would rather not buy a third. Thanks, Bob Becker 1982 M15 #208 SF area
