We installed a 4:1 Garhauer (found in the boom vang
section of their website, line was included but too short for mainsheet, but did make a nice new reefing line) on our 36' Yawl. By the time 4:1 is not enough we have already reefed, so it is fine again. Boom end sheeting point.
To do it again I would probably select their 3:1/6:1 system, a bit pricier but I think worth it.
Ratchets required for only three reasons:
1 Load becomes intolerable, so you risk rope
burns when easing, or losing control of the sail (while sheeting pull through the cam, so ratchet effectively does nothing)
2 load was designed that way to speed sheeting , more purchase
, more line to pull, less purchase
= less line = faster mark roundings.
3 no cam cleat provided, so line is always under load, and your hands get tired
I have raced many more multiples of miles than I have cruised, as long as effort is manageable, then frequent adjustment of trim is part of the fun of sailing!
