I have been very dissapointed in trysails for making progress, but they make a truly great roll stopper. My 2 cents worth,____Grant.
Now that sounds like an excellent idea. Plus you don't have to buy or rig any extra kit, just using something that's already there.

Well if one carries a spinnaker pole. I only carry a whisker pole. I guess it would be possible to rig guys and such to make it work for a flopper stopper. Then the main boom could be rigged for the other side again with the addition of a few extra lines here and there.

That would give you a pair of jury rigged outriggers (say that ten times in a row real fast) but there is still the problem of carrying and stowing a couple of big, weighted fish to hang on the ends. In my boat I just don't have the spare room for a item that would be occasional use and single function as well. Now if I could figure a way to hang them on a halyard and swing them around the boat to repel boarders.

Re: Slamming main in calms

I had read about it in an old sailing book and tried it in a rolly anchorage in Hawaii, and it worked wonderfully, and I tried once at sea and it was great. What ever my next boat will be(hopefully soon) , if it needs a new main , it will be cut with 3 reefs and I will recut the old main as a steadying sail or if it has a good main ,I will pick up an old one and make a steadying sail out of it. It made the differance between having a coffee cup launched across the cabin and being able to set the cup down and not worry about it. Little tricks can make life better.____Grant.

Re: Slamming main in calms

I have heard that a light air main made of nylon works well. Because nylon stretches there is no slamming load. Also it keeps the boat moving a lot better than a normal main in very light winds, 2-4kt.

The version called the Mainster has the foot and luff loose and the leach is cut hollow so no battens. This minimizes storage space and rigging complexity.

Drives me crazy. The only time I've ever mutinied was on an offshore race when the owner of an Andrews 53 I was crewing on called for leeward weight on the rail when we were becalmed and the *)(*<#&!! kevlar 155% genoa was slating.

Told him exactly where he could stick that sail. (To leeward, of course.)

Re: Slamming main in calms

As about half the posters have said...DROP-THE-MAIN!

I agree with this ... if the situation has not improved after setting a preventer, then using the traveler to tighten up ... and tightened sheet.

Hi guys,

Thank you for the input, much appreciated. We are "sailing" down the portugese atlantic coast at the moment and keep losing the wind , the atlantic swell remains though! Hence the post.

Looks like lighter winds ahead for a week now, so will get a chance to try out a few of your suggestions :-( and will report back.

I once saw a yacht in the gulf stream in light winds with twizzle double wing on wing jibs set and a trysail ! This must have been to dampen the roll as mentioned. Thinking about it, it sounds a great et up.

I do have a trysail onboard somewhere.... Isn't it funny how lots of people use 3rd reefs and trysails in calms , another example of things on board having more than one use!!

Charlie.

We sailed from South Africa to Brazil using double Genoa (one to port one to starboard) ... was fantastic sailing but in light winds the one tended to collapse into the other

No problem. If changing course and sail trim cannot quiet the sails I take them all in. Either sleep until the wind comes back, or sand and varnish something, clean the bilges, whatever.

Re: Slamming main in calms

Lots of great ideas!
Thanks for this thread. I really like the idea of a lightwind main made of spinnaker material but the other ideas are equally as great.
kind regards,

Re: Slamming main in calms

I too appreciate this thread. Next time I am slatting I am going to triple reef the main and then tighten the staysail in one place and see if I can get through it. Blowing the main and motoring always seemed the the chicken way out- and a lot more rocky.

Has anyone tried using a rubber or bungy on the preventer and mainsheet to reduce the shock loads on the mainsail and boom when slatting in light airs? Read about it once but I have never tried it, seems like it should work.

That still doesn't prevent the sail from slatting though

Very true, but the elasticity should reduce much of the jarring shock loads that make it so hard on the nerves and the gear. Often you have a decent sailing wind, but the odd swell will still knock the wind out of the sails every minute or so. A bit of stretch in the system might stop it jarring everything quite as unpleasantly. Just a thought...
