The owners manual says 3/8 x 75 feet but if I remember correctly that is about 8 or 10 feet longer than needed. However if I was buying one without the old one to measure 75 ft is what I would get. Dave

If we are talking mainsheets...It depends on if you have a 3:1 or 4:1 purchase on the mainsheet. I replaced my 3:1 with a 4:1.

On "TSU" I have a 3-1 purchase and I believe that I bought 60' of line.

Don... That's interesting--Passage came to me with a 4:1 rig, and I've been considering changing to 3:1 (very low on my list). The 4:1 makes sheeting virtually effortless in almost any conditions, but it seems to require moving (and standing on) much more line than necessary. (I guess it's 1/3 more than 3:1.) In light air, it almost seems to impede sheeting out. Do you like the 4:1 better?

Dave - originally I had a 4:1 on the mainsheet, but I found that it tended to "hang-up" on the pushpit with the friction of the 4 lines. It also made for very slow trimming coming around the leeward mark and there seemed to be surplus line all over the cockpit! Since changing to a 3:1 I've not noticed any more difficulty in trimming, even in high wind, and it does make easing the mainsheet quicker as well.

I picked up some really cheap lewmar racing blocks with 6 to 1 purchase. Our old block and tackle was just short of non functional and the price was right. I was okay with 80 feet and have plenty of tail on all angles of sail. If racing in light air, I plan to re-rig the blocks and only go with 4:1 or 2:1 so that I don't have the problem Derick was talking about above.

I've never noticed any problem sheeting out with the 4:1, although in light air I do have to help it out a bit, but I would have to do that with a 3:1 mainsheet also.

As for the extra line...what is it...an additional 16 or so feet? In a coil of 70-80 feet it is not noticeable.

I switched over to the 4:1 mainsheet because the original 3:1 became my new vang. After aquiring the new 4:1 blocks on eBay for a small fraction of their original costs, I used a larger line for the mainsheet for the better hand (I'm outnumbered by females in the family by 3:1) which makes it easier for them to put some tension on the mainsheet.

6:1??!! Wow--when you uncleat the sheet, the weight of the tail should haul the main in by itself! But Duane... what do you do with all of that line when you're close-hauled?

I have some new fandangled lightweight line, there was a "dead end" sail at layline a while back and picked some up for dirt cheap.

We must have had a really long mainsheet back when we were 3:1 (might have been 4, I cant remember) because it doesn't seem like we have a longer tail... at any rate, it sits on the cockpit floor
