Looking to replace my furler line on a CDI F4 and won't be out to measure for awhile, any ideas on length? I relize it may differ depending on how it's rigged.
This one is ran along toe rail to cockpit.

65-70 ft
You can make it shorter but it’s nice to have excess that you can trim as the line wears.

It's always a good practice to measure your existing line. People often guesstimate the length needed. The result is often that the line is too short by a foot or two, or too long by a lot.

If your existing line is too long or too short, it's an opportunity to correct it with the new line.

If the line is too short, it's probably useless. If it's too long, you'll have it creating a tripping hazard on the cockpit floor, or it might drag in the water behind the boat, and, in any event you'll have to coil it again and again every time you put it away. When you buy a line that's too long, you'll pay for line that you'll never need or use.

A key variable is the size of your jib/genoa. The larger it is, the more turns on the drum are needed when it's unfurled. It's best to go by what you have now, and as Steve says, adjust by whatever excess or shortage you have when the sail is fully deployed (maximum wraps on the drum). You want a few feet for cleating and grabbing. There should also be a couple of turns on the drum when the sail is fully and tightly furled (with a few extra turns to wrap the sheets around the sail), to give some leverage to keep it tight. If a storm wind gets inside the leech of the furled sail, it can get ugly!

The other factor is the thickness of the haul line. If you don't know what size is on there you might oversize it accidentally. Thicker line will increase the drum diameter a little more for each wrap, and the larger diameter will require more line for each subsequent turn. The difference in length can be significant. In fact, going to one size up in rope can produce so much extra diameter that you end up with a wad that binds on the surrounding shell - I discovered this the hard way with my Harken. I can't advise you on the CDI furler, but the other guys here who have them certainly can tell you what size rope to buy.

By the way, make sure you have enough length to tie a large stopper knot in the end so you don't lose the end when the sail suddenly catches wind and unwinds faster than you expected and whips the end away from you.


The trouble with a destination - any destination, really - is that it interrupts The Journey.
