Tom,
There are another options.
The FCA Blade has a single bolt with its head under the mast base that allows adjustment. Quick and easy to adjust.
I understand there are other boats like the Nacra Infusion
and latest carbon rigs from Marstrom use a similar system.

Others like Stealth and some Tornados have a single turnbuckle on the front of the mast but you may need a bail to delfect the jib as it passes.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
