I currently have Barient 28's not st's. Want to replace with new Lewmar or Harken Self Tailers. Don't know much about winches but have been reading up. It seems as though the recommendations from the above manufacturers are suggesting a smaller diameter winch drum than that of the Barient 28. I know rope diameters have become smaller due to increased strength/tech. Is that the same for winches? Were mine over sized for some reason?
I have a 135% genoa now, but may purchase a 150% in the future if that helps any. The boat has been in the San Francisco bay for a while (since it's launch??). I'm planning to bring it to the Southern CA area next summer, where winds are much lighter.
Thanks, in advance, for any replies.

A winch is essentially a lever. Much of the power is gained by the difference between the diameter of the drum and the length of the handle - smaller drum diameter is the same as a longer handle. As long as the drum diameter is large enough to spool your line without problems, it's wide enough. The big, powerful winches have such large diameter drums because they have big gear trains inside that have to be enclosed by the drum. The guts of my old Barient 736's look like a Muncie 4-speed from an old muscle car.
