Looking to assemble a vang for Cindino, our Hughes 25. Does anyone have a
method of calculating working loads that might be expected/generated by a
main of 145 sq ft.sail area?

When I look at the various pre-assembled vangs out there they are basically
3 sizes; small, medium and large. The large looks fit to cross an ocean, and
the medium would still be the beefiest hardware on the boat but I am not
sure if the small is big enough.

Any suggestions?

On a 25-footer? Small is plenty big enough. We had a Dawson 26 (25'9") on
which we installed a small rope and block vang. Woked just fine. Now we have a
37-footer that came with a rope and block vang. We replaced it with a solid
vang. Huge difference. It's a matter of how much leverage you want to be able
to pull down the boom. I think the solid vang has about double the purchase of
the rope vang.
