Wishbone for self tacking jib

[Alexis]

Hello there,

Has anyone any experience in using a sailboard wishbone on an trysail or jib so as to make it self tacking?

Any advice welcome.

Cheers,
Alexis

Have a look at Island packet yachts,they have a boom arrangement on their cutter rig.

Thanks for the tip. I know this sytem, known as Hoyt jib boom,or something along those lines. You can retro fit a kit which is well over my budget. I am thinking of making one myself, but am looking for a quick and simple solution, hence the wishbone.

Got as far as designing it...

We actually have an ordinary boom on our staysail; I reckoned the wishbone would be better. You need to have a way of securing the wishbone to the forestay, so that it can slide up and down and can be removed to stow the sail.

adding the boom so far above deck may effect weight/balance of rig and am wondering whether the boom can be attached to the forstay when norm attached to the mast. jib boom may be easier to do.

Have a hunt around for the Bierig (Beirig) Camber Spar - might be easier to make something like that (assuming you can mod the headsail to accept). Failing that, lots of cruisers use wishbone booms, but again, you need to mod headsail to allow for the "kink" in the luff.

Too heavy
Use the carbon fibre mast insread and cut to size. use the lanyard and outhaul fitting from the wishbone at the clew and run the line forward and fit the jamming cleat there. At the stay end epoxy a catapult handle in the end of the pole and secure the gap with strong bungee. Ever so cheap and the bungee serves as the weak link if snatched or over winched .

Get the pole and the broken wishbone from your local windsurfing lakes skip . You might even fond a topper boom end fitting instead of the catapult, alternatively a rowlock.

Have fun
