I have a stail sail boom with two deck eyes about 1m apart what blocks/ sheet system could i use to work a sheet from this? Would it self tack once set?

What size boat is this on? Knowing that will help give an idea of what type of purchase you need.

One of the advantages of having a club footed staysail is that it will be self tacking. Generally, there are either two eyes spaces apart on the deck or a sheet horse to keep more downward pressure on the clew when the sail is let out a little bit.

If the sail is small, you could dead end at one eye, go through a block at the end of the club and through a turning block at the other eye to a place to make it off. If it is a larger sail and you need more purchase, you can use the same system but with the sheet doubling back on itself.

Given the size and not knowing the sail area and club length, I would guess that a 4:1 purchase would make sense. On one eye, you need a block with a becket and on the other eye you need a single block and the club gets a double block. You go from the becket to the double block on the club to the single on the other eye to the double on the club back to the single on the first eye and then to whatever it makes off on.

Unfortunately I don't have a picture of this setup but it is used on a lot of older traditional boats.
