Winch replacement
We have an O'Day 30 on the Chesapeake. The boat had the original Barient 21 winches. At the recent Annapolis show, we talked to several winch manufacturers for a replacement. No one makes a direct replacement. All suggested at least a 40 and even up to a 46. We went with the self tailing 40. The new winch has a different bolt hole diameter, so we are going to have to fill at least all but one of the holes and maybe even all of them before we redrill them.

If the bolt hole circle is larger than the original I would consider filling all of the holes and center the new hole circle over the original, assuming that the number of holes is the same, then space the new bolts between the old ones. You would have a more solid base. Also back with a suitable sized aluminum plate or 1/2" to 3/4" plywood.

The bolt circle for the new ST40 winch is larger than that for the original Barients. Centering the new winch over the bolt circle, but staggering it so the new bolt holes straddled the old ones, was one of the options I was going to look at once the boat is hauled for the season. The installation of the port side winch should be relatively easy through the lazarette. The starboard side winch is going to be significantly more difficult as there is only about a 6-inch diameter access port to reach the nuts. I had also been thinking about using the backing board, but I have to look at the flatness of the surface it would go against and what I could wedge the board against to keep it from rotating. For the backing board, I was considering using some of new manufactured composite deck boards in lieu of wood.

If I may offer some information, consider your options on the mounting method, see: www.westsystem.com/ss/bonding-hardware Usually once a manufacture develops a product line/technique it follows through the entire line, a signature if you will. The top of the cockpit coaming is a composite which uses a plywood core on the ODay 27. I would suspect the entire ODay line uses this same method. Whichever method you use to mount the new winches make sure they are watertight as that area would be a pup to repair with all the curves and narrow widths involved. Best wishes, Joe
