conversation from sloop to cutter

I am considering on converting my 36' sloop to a cutter. Does any one have experience, guidlines or referance material to review.

You'll need to move the mast. Cutter masts are considerably aft. I think what you want is to have an inner or solent stay for a second headsail, no?

Re: conversation from sloop to cutter

I've thought of doing the same to my 28 ' sloop. If you look at other boats there are many sollutions. Baby stay with quick release turn buckle, retractiable bow sprit, Perpendicular stay's the come from the same top spot but one is a meter aft on deck, to name a few. Call Christian at Dam Rigging in Ft. Lauderdale or Sailing Services in Miami, they will know exactly what your options are and how to best achieve your goal. I havent decided what I'm going to do yet. Moving the mast seems a little drastic. You just want to add a stay to create a slot and have a smaller head sail in heavier weather correct?

Re: conversation from sloop to cutter

It can be done, but it isn't as easy as just bolting on a new stay. The loads imparted by a sail can be quite large, and the attachment system needs to be properly designed to handle the loads. This can lead to two different processes.

1) hire a NA to run the numbers and confirm the location and strength of the components to ensure everything is strong enough.

2) use a good rigger that is experienced to define the system that you need.

Assuming that the inner sail is going to be used in storm conditions, not as a supplemental stay-sail for light air, the forces can be very high. Depending on size and placement the staysail can actually have higher loads than the geneoa. So it is critical that everything is sized appropriately.

Re: conversation from sloop to cutter

If you don't move the mast and completely reconfigure the rig you won't have a Cutter, you'll have a Slutter, which name might tell you something.

Re: conversation from sloop to cutter

It would certainly help to know what kind of boat we're talking about, for starters... Talk of relocating the mast seems premature, some older designs like mine that carried a tiny main and a large foretriangle, might accommodate an inner forestay mounted 25% of the J dimension aft of the headstay just fine the way they are...



Such a conversion can still entail considerable work and expense, however. Few boats will handle the loads on the foredeck without the construction of some sort of supporting bulkhead, or a tie rod taken to the hull... Then, you need to work out your running backstays, as well. One thing I'd recommend to try, if possible, is to configure your inner forestay/running backs so that they are above the height of your deepest reef in the main, and can be attached at deck level far enough aft so that they are clear of the end of the boom... This will give you an added measure of security in a blow, when you can leave both backstays on, and jibe or tack without having to worry about releasing one or the other...

You also want to figure out how you want to stow the inner forestay back at the mast when not in use. Easily done if you're just hanking on the staysail, a bit more problematic if you're gonna go with a furler... But it can still be done, and really worth doing so for those times you might simply be sailing the boat as a sloop, short tacking, or whatever... I'm a big fan of the Wichard pelican hook style adjusters for attaching the stay to the deck fitting - pricey, but well worth the money, IMHO...

I'll confess, I've become totally spoiled by having my staysail on a furler... I sailed for a few years with a hank on staysail, but it's just SO much easier to switch gears with a pair of furlers... Just finished up the delivery of a Valiant 42 with a hank on staysail, we had to resort to the use of it a lot on the trip, and it's a good thing the air and water was warm... But I'd forgotten what a PITA dealing with a hank on staysail can be on a smaller boat in a blow (especially if you're stowing your tender up forward), and there are lots of times I'd rather not have to venture up there if I don't have to...

Re: conversation from sloop to cutter

Also you might need to fit running backstays. I have a heavy section mast but am happy that I have the running backstay set to support the section of the mast where the staysail is fitted when it is blowing 25-30 and there is a 3 metre swell running and I am hard on the wind between islands.

pedant mode on

I clicked on this expecting to find a dialogue betwwen two boats, one sloop rigged and one cutter rigged.

pedant mode off
