This may be a dumb question but why is it that anytime somebody talks about main sail furling they talk about in mast furling?

I would think that in boom furling would have some advantages over the mast version:
- shorter rod means easier furl
- the weight is lower and smaller
- it's more like an infinite reefing system.

To me the last point, the fact that when you reef you bring the sail down, would mean that in-boom furling would give a lot more reefing options.

Am I wrong? Are in-boom reefing not available?

Regards,
Dave

What I like most about in-boom furling is if you get a jam of any type you would still be able to drop the sail.

THere are in-boom furling systems, and they have advanced far beyond what was common in the 1970s for boom roller furling.

Slab reefing is less weight aloft, less expensive and simpler, and that is why it is still so commonly used.

Just. Say. No.

I had it once, hit a nice squall on Lake Huron and had the mandrel pull out and get jammed in the sail exit slot. Switched to slab as soon as we got home.

Also sail shape leaves something to be desired with these.

A "Dutchman" system and conventional slab reefing- that's what I'd recommend.
(Especially if you have a long boom)

Thank you for your input. So I wasn't going nuts: if you are going to use a furling system for your main, you're better off with boom furling rather then mast.

Regards.

yep. IMO:

Slab= Best

In boom= Worse

In Mast= Worst -ever try to brail a whipping main in a gale?

I wouldn't be too quick to condemn boom furlers based on one bad experience. My opinion having used all three on different boats is boom furlers as my first choice followed closely by boom furler as my second choice and for #3, guess...

Well, that depends on what kind of weather you sail in. I like to plan for the 10%, not the 90%.

Round here, the 90% can turn into the 10% pretty quick.

YMMV.

My thinking of the whole mast furling thing changed in last weeks 190 Around Long Island Race



We start at 5:20 PM Thursday and sail off into the night towards Montalk with the other 35' Spinnaker boats and are normal assortment of 50 lines in the cockpit and 12 sail changes over the next 24 hours till we Pass plum-gut and head west on Long Island Sound

So there was the normal wind/no-wind and what pulls up on and easy reaching leg 100 miles later :rolleyes: a Catalina 445 with roller everything in the cruise division

And i gotta say the new furling mains look pretty dam good ;)

I have in-boom furling from John Mast with a fully battened mainsail.

  • Easy for single-handed sailing
  • Can reef any amount of sail
  • Additional weight is kept low (unlike in-mast systems)
  • The sail is always rolled away in the protective boom (my main is 8 years old and looks like new) it makes the boom rather hefty for my small boat
  • I can (just) raise the main if not into wind, but usually I point up to make it easier
  • It runs smoothly if I spray sailcote on the track once a year and replace the halyards and downhaul every 2-3 years (like this I can drop the sail very quickly)
  • The sail shape is ideal, unlike in-mast reefing
The system was on the boat when I bought it, otherwise I would not have fitted it - it's very expensive.


All in all, it's much better than in-mast reefing and a little better than lazy jacks

OK guys, I'm thinking in-boom furling would make sailing a lot more fun for me. Taking down and flaking the main is a major pain in the butt. I hate running up my main because I know I have to take it down again and it's not fun.
What would a ball-park figure be to add in-boom furling to my Catalina 34? Any thoughts on different brands? How will it affect re-sale?
Can I re-fit and use my current main sail or do I have to buy new?

You are fortunate as your main isn't that large so you might be able to get away with a smaller boom package but expect to pay close to $10,000 for anything worth having. That price will probably include a std dacron mainsail.
Resale value might be minimally increased but never to the cost of the new boom.

If you putz around in lakes and bays, I supposed you ought to have any system that rings your bell. If you sail offshore, the simpler the better, because Murphy's Law is always in effect.
Slab reefing is the simplest, least apt to fail, and doesn't lessen the stregnth of your mast or boom. If you are lazy about flaking the main, then add lazy jacks - but I can tell you from experience, if you get caught in a real blow and need to reduce sail, they can impede your dropping the mail.
