Lewmars are good winches, and self tailing
is a nice touch for any boat. As far as size goes, I would look at the primary winches that are on your boat now, and compare diameter, and power, and decide from there. The Vega is a well designed boat , and not too heavy, so the same basic power, or slightly larger should work fine. The cost of larger winches might be small compared to the cost of redoing your winch bases (fiberglass work, or fancy SS fabricated bases) and the time involved. I dont recall
if the Vega has secondary winches in the cockpit
, but they are very handy for cruising. Just something to think about. Good Luck. _______Grant.
