Greetings,
I've searched but cannot find length and diameter recomendations for jib sheets. My "new" old boat came without these. Different sheets for 150 vs 100?
Thanks, Walter #232

A while back I asked the same question to one of the more experienced sailers in our fleet. He responded as follows:
Get a 50 foot jib sheet that has a Dacron cover, so it doesn’t slip on the winch so badly. “XLS Extra” by Samson is my current favorite. You can mail order or get it from Fisheries Supply (in “Mariner Square”, just north of Lake union). It has polypropylene/aramid composite core. The polypro is light and doesn’t absorb water, and it provides most of the bulk of the line, and the aramid provides the strength. Less slippery means fewer wraps, which means faster handling and fewer overrides. Fatter helps this too. Class rule requires it to be at least 8mm (5/16”), which is what your current one is. 7/16” and even bigger is fine by me. Some people like a skinny sheet, mostly because it doesn’t weigh down the clew of the sail in light air, but I don’t think this is a big enough issue to give up the handling advantages of fatter sheet—but notice that I do go for the lightest fat line I can get with the Dacron cover…. The 50 foot length allows it to pass over the spinnaker pole when it’s at full height. Your current sheet is about 3 feet too short and has a polypropylene cover, which is slippery and will wear fast on the winch. Dacron cored ropes (e.g. New England’s Sta-Set) stretch under the high loads put on a Jib sheet (or halyard). You won’t notice this until you’re trimming the genoa in 12 knots or more, and then you will… you’ll especially notice when it’s windy enough to require the small jib. Sta-Set is one of my favorite ropes for control lines—it’s cheap, stable, easily available, doesn’t mind being left out in the weather, has an excellent “hand”, comes in a huge variety of colors. Downside is that it absorbs water, so it gets really heavy, and it stretches way too much for halyards. West Marine carries it, so you can get it anywhere.
Since then, we have decided that we do not like to route the sheets over the spin pole. As a resuilt we have significantly shortened our sheets. Instead, we go with as short a sheet as possible, in order to keep clutter out of the cockpit. I don't know the actual measurement, but the way we determined the length is to sheet it tight on one side and trim the lazy sheet with just enought for a figure 8 stop knot a thre lazy block. |
