I believe to get correct sail shape our sheet blocks will need to be mounted slightly aft of the mast, so a curved track in front of the mast isn't an option for us.

I found one guy online who has attached a block to the clew of his staysail, and has it rigged to run on a single line. Self tending, but it seems like a very unusual arrangement to me, I imagine it would behave quite strangely when sheeting in or out... any comments on this?

Resize the picture in any photo management program, like MS Photo Manager or others, then resave it as repost it.

Odd that that picture shows a traveller track for a self tending staysail on the cabin top already - though it looks like the current staysail clew is too far aft for it. I suppose the arrangement may work, but it will be difficult to control leech tension with that setup.

Whoa nellie! Yeah, that's a jumbo photo for sure.

You should go back to your photo-hosting website and choose a smaller format for this photo. It's hard to get much perspective with it being so large...

That's an odd sheeting setup, especially considering that the inner staysail is generally going to be used in heavier weather quite often, and you'd want to be able to sheet the staysail as flat as possible.

There are single line, self-tacking setups for jibs/staysails that don't require a boom, but the generally do require that the staysail be cut a bit smaller than you would without a self-tacking setup. Using curved traveler track is quite common, especially if you look at some of the smaller boats, like the Sonars—where I've seen them setup that way quite regularly.

He'll have to resize the photo using something like IrfanView, since he's hosting the photos on his own site by the looks of it and not using a photo hosting website like Flickr.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Thanks Dog! I didn't know about that option --- well beyond my paygrade.

You're welcome. I think the track is angled so that when close hauled it can be sheeted in close but you still have the option of moving the clew position out for a beam reach or broad reach/run.
Thats just what I surmise - More experienced/knowledgeable sailors feel free to correct me.

I removed the jumbo image and replaced it with a link. It's not my image or my site, just something I found online.

I finally found an image of another Mariah rigged in this fashion. You can just barely see the track there. It also appears to have the track mounted on an angle out from center, like the picture that GBurton posted. I'll have to do some more research on why that is done...



Thanks for all the replies.

Here's a theory... as the wind pipes up you generally ease the leads aft.. allows some twist to depower the upper part of the sail and ease the heeling forces. Moving the lead outboard at the same time reduces the angle of attack, again easing pressure.. perhaps at the cost of some pointing ability. But it also eases the backwinding of the mainsail ..
