I'm replacing the running rigging on my 1977 Ericson 27' Tall mast. West Marine is having a 40% off sale on sta-set poly lines tomorrow so it seems like a good time =) Unfortunately I'm 3,000 miles away from my boat, so I could use some guidance. I've done research, but would be great if someone could vet it for me.
Mast is 34', boom is 10'. Halyards are winched and cleated onto the mast.
Main/Jib Halyard: 3/8" x 45'. It will be attached to a wire that hoists the sail, so I only need one mast length. I figure mast length plus an extra 10' or so for emergency situations (hauling someone/something from overboard). Is that overkill? I've seen some places specify 5/16", thoughts?
Mainsheet: 3/8" x 65'. This is the one I'm most unsure of. My mast is tabernacled, so I'd need to lower it. Doing some basic math, if it's 4' block to block when the boom is horizontal, It would be ~17' block to block when the mast is down and the boom is vertical. Multiply that by 4 for the 4:1 block and tackle (52') and add 10ish feet for some slop. Should this be longer?
Jibsheets: 3/8" x 40'. Boat length * 1.5
Boom Vang: 3/8" x 20'. Boom length * 2
Outhaul: 5/16" x 20'. Boom length * 2
Topping Lift: 5/16" x 20'. I'm just guessing on this one. Would 1/4" be OK? I'll probably get this one extra long just in case (it's always good to have some extra line anyway).
Seem reasonable? Thanks!
