Joe,
My 35-1 has a 6:1 purchase on a Harken traveller, and I have to pull
reasonable hard to get the boom tight in any kind of breeze. I don't
think a 4:1 would do it. That said, in light airs the 4:1 would be
nice. Maybe you could use 6:1 but drop it to 4:1 in light airs, which,
having sailed out of Annapolis for 5 years, I know you get a lot of in
the summer.

I just now unrigged the mainsheet and replaced it with a 4:1 mainsheet and cam
cleat that I had as a preventer for a proof-of-concept. The preventer has been
on the boat for so long I forgot where it came from, but looking at the
mainsheet systems online and at Bacons it became obvious this IS a mainsheet so
I decided to try it out. So far it has only got a light air test, I am loving
the lack of friction compared to the stock system that goes up to the mast and
back to a winch.
My question is this; will 4:1 be enough? Bacon's has a 6:1 mainsheet for a
reasonable price, I can buy that and send the 4:1 back to preventer duty easily
enough.
While I was at it I noticed the vang, one of those Quick-Vangs with a spring,
had the line fed through a turning block far enough from the mast that it had a
significant change in tension as the boom swung. I have no idea how I haven't
stared at this for decades and not noticed, the yard installed it ages ago and
I just never realized they did it wrong. Now the line feeds to a turning block
almost at the pivot point, changes in tension will be almost nonexistant.
