That's weird somebody posted almost the exact question about a week ago.

How do you mean the battens don't fit the mast????
The battens have to go to the luff sleeve otherwise they might as well not be there! You don't cut battens down and expect the sail to work the way it's meant to.
Is it a cammed sail? if so cams meant for a rdm won't fit an sdm, in which case the easiest way out is to change cams.
Do you mean the battens are sticking out in front of the mast and the sail doesn't rotate?
If so you probably haven't got enough downhaul/outhaul, or the base of the mast is too stiff.
Does the mast have the recommended stiffness and bend curve?

the only severne 5.7 sail i found using a quick search was the 2006 S-1
which seems to be a "maneuver oriented wave sail"
http://2006.severnesails.com/products/sails.asp
and specifies on the above page RDM ONLY
and that is WHY your battens "don't fit"
the sail and battens are made for a Severne Redline 400 cm RDM mast
would i cut the battens NON
do you have the $$$ for a mast - non - AND donut care about the sail - ONLY then cut the battens !!!

I think like decrepit said check you've got a mast/sail combo that match, other than that , more downhaul,

you shouldn't cut battens, they're cut to the correct size for the sail they're in already by the sailmaker.

They'll look too long if there's not enough downhaul or rigged on the wrong mast, if they're really not rotating then get someone expert looking to have a look at the beach one day whenn you're rigged, if the mast is the right bend curve they should rotate, even with an sdm.

I should add if you were to cut them, you'll later discover they have to be the length they are now to fit the batten pocket, any shorter than a few mm and they won't even sit in the tension screw

Ah subsonic you've hit the nail on the head. The battens have to apply tension to the sail by being tight at each end of the pockets.
If you shorten the battens then you also have to shorten the pockets, so the sail stays tensioned.
There used to be, many years ago, what was known as "soft" sails, these had a few battens around the boom area, that didn't go all the way to the luff.
This allowed a full sail that still rotated easily.
But you can't just stitch the batten pockets up, there needs to be enough reinforcing in there to hold the tension on the battens.
If you've nothing to loose may be worth a try, but remember I'm not actually advising it, think I'd rather get the correct mast.

This is the same question I asked a week ago but I put more time in to fitting it ,max down haul and out haul but still the battons are way to long,the lower battons are the worst,the std mast is old school one piece and I'm planning on going to rmd so I don't want to buy a new mast just for the old sail. There are no cams,and the existing battons just push hard against the side of the mast ,I dout they will even pop.im going to cut them,I can't see any other way ,will let you know how it goes thanks for the replies legends.

I would encourage you not to. You will then have a sail that won't work on any mast.

You're missing the concept...loosen them right off, that's like cutting them down, still wont help you'll just have a wrinkly sail.

If you shorten the batterns, you'll have to shorten the battern pockets at the mast end. In other words forget it

I would say if you're trying to rig it on an old one piece mast, that'll be you're problem right there....

I know it's probably not what you want to hear but I'd probably lash out and invest in a newer 400 2 piece mast (constant curve if you're running severne sails). it'll open up the possibility of being able to use a lot of other sails as well.

I'm guessing you'll struggle to find sails that will fit your one piece mast these days...

this says you don't have enough downhaul. maybe you need to get someone with current gear to show you just how much downhaul is enough.

years ago I went for a sail with Andrew of KA sails, after rigging my sail with what I thought was heaps of downhaul, I asked him "was that enough downhaul". He replied " before you can say you have enough downhaul. First you have to have SOME downhaul."

DON"Tmess with the sail. Get a decent mast.

don't cut them

unless they are the wrong batons for the sail (highly, highly unlikely)

agree with others, haven't seen a one piece mast in so many years - its bound to be that - sail and mast incompatible

get yourself a new mast, even 2nd hand and watch that baby rig right

all you are going to do by cutting them is create the need for new batons (and you'll still need a new mast)

Couldn't even get them out so left it,looking for a skinny mast hope it has more room to fit around the battons.
