Sorry to be late to the game, was on an email hiatus for a while. Yes, I put in a 12:1 tackle. My boat originally had no purchase at all. I did it by: 1. Running a piece of spectra thru the clew, one end dead-ended at the back of the boom and the other end into the sheave at the back (this gives 2:1 off the bat) 2. Attaching a single block to the end of the spectra, and running another line from the front of the boom (this end is dead-ended), thru the block, and back toward the front (this end is the working end) (this gives another 2:1) 3. Attaching a single block with a beckett to the free end of the line above. (this gives 3:1 on top of the last purchase) The other ends This last one was the trickiest, because I had to mount a single block on the inside of the boom to be the other part of this purchase. Drilling and Taping and threading, etc. but I used my "drill-tap" and it came out great.
Adding up, we have a 3:1 pulling on 2:1 pulling on 2:1....so 2x2x3 = 12:1 I used spectra for all of it except the last line. You only really *need* spectra for the very first line on the list, because it's going to pass thru the clew without a block, so a low friction line is best. I used spectra for the middle line because it's absurdly easy to splice. I used a regular 5/16" double braid for the last bit so it's easy to handle. No winches needed. The *only* time that the friction is a problem is when I'm at the dock, have forgotten to de-tension the outhaul, and have to pull it loose by hand. My mainsail clew doesn't have a slug as many do, instead I have a long (4' or so) webbing strap that gets wrapped many times round the boom. Both faces have Velcro on it, so each wrap sticks to the next. I leave it with about 1" of gap at the top so it's loose enough to slide along the boom when I adjust the outhaul. As for how to keep critters and birds out of the mast, I took a big sponge, maybe 7"x5", and folded it in half and stuffed one in each end. It's big enough to fill the whole space, yet let the lines pass. After a few days, the dryed sponge will get hard and wedge itself in place. When I need to get in there, I just re-wet the sponge and it becomes pliable and easy to remove. -Keith M 35/3 Beyond the Sea -----Original Message----- From: Graham Collins [mailto:[email protected]] Sent: Sunday, December 30, 2012 9:30 To: [email protected] Subject: Re: Stus-List Outhaul Hi Joel On mine there are no blocks inside the mast, my outhaul runs straight through the boom, down to the mast collar at the deck, and aft on port side. To adjust it we have to put it on a winch in all but very light winds. I think Keith (also a 35-3) has blocks internal to his boom, if I'm recalling correctly he said 12:1, which means you could adjust it with two fingers, but would have more friction obviously... if he is on maybe he can confirm/deny that recollection.
