I am planning on rigging my C25 with a cabin top winch for raising the mainsail. I have access to a Lewmar #6 and #8. Would the #6 be big enough or should I use the #8? (We just moved up to the C25 from a Venture 17 with NO winches, so I'm not experienced in this area...yet).
I believe the stock cabin top winch was a Lewmar #6 single speed. Although tempting, I don't think you need any bigger than that on the cabin top. Number sixteen self-tailers would be nice for the primary's though.
Concur with Al's opinion. Lewmar #6 is the standard Catalina 25 halyard winch, and it's got more than enough "power" to raise and adequately tighten the luff on a mainsail with even a short 6" winch handle. If it takes a huge amount of effort to hoist the sail, the slides and the mast slot are probably dirty or sticking and you should clean and lubricate them with "SailKote" or a similar product. Use of excessive force is liable to break the slugs if they are the cheap plastic-only kind without a metal loop. The standard primary winches are Lewmar #7 or #16ST, so your Lewmar #8 is larger than even the primary winches need to be on a Cat 25.
