This site shows what looks like the simplest and cheapest hardware
to set up a removable solent stay using a spectra tackle lead back to a winch
instead of a Highfield lever.
Solent stays and storm jibs | joecoopersailing.com
Ive used tackles before with success, Highfield levers and just normal turnbuckles with handles. One Big boat even had a hydraulic ram to tension the solent stay. But when I get around to setting something up on my new boat I am planning to use a dynex dux forestay, soft hanks and a series of low friction rings to tension the thing. Its nice not to have to deal with heavy hardware when the bow of the boat is bouncing all over the place.
If the chain locker bulkhead is sturdy and well glassed in it would be ideal to attach the stay to. Just make sure the deck fitting is tied into the bulkhead properly.
I have lashed a stay up the top of the mast
using spectra, a few passes around the cap, and around the mast above the track with plastic tube over it to stop chafe. It worked well for a few years until I made a proper fitting.
In your case you will probably need a halyard
as well, though if you have twin jib
halyards one can be adapted to work with a fairlead just above the solent stay. You tie the halyard
onto the head
of the sail with a long bowline that also goes around the solent stay. It works fine, but a big shackle would work as well.
