I have a BAV 40 / 2002 and had the original genoa winches (if memory serves, I am not on the boat) Harken 44s onto the coachroof replacing/upgrading the working winches (again if memory serves Harken 36), moved those to the aft as spinnaker winches and got new Harken 48 for new genoa winches. The 48s fit perfectly in place of the old 44s. Fitting the 44s on the coachroof was a bit tricky but I got it all done for cheap in Tunisia. Imo winches can not be big enough, especially when sailing with my kids and wife.
