Sheets

Do Jib sheets really need to be stretchy? I see race boats with some pretty low stretch lines. For our boat's jib sheets, 1/4" Spectra (Amsteel) would be more than strong enough. So if you could fatten it up and put some cover on it, what would be the problem?

Re: sheets

No problem with using spectra, but more expensive than needed and why go to the hassle of fattening and covering when cheaper, larger line will do the job,

Personally, on a 36 ft cruising boat, I'd go for 3/8 (10mm) polyester double braid (or maybe even 12mm).

Handling. It's all about the handling. I'd use 1/2" or 9/16 if they still sell it.

Re: sheets

I'm trying to set up a second sheet so I can put the clew in the slot between the top and forward stays. Having to re-rig just one sheet through the 2 snatch blocks to the winch is a big pain and dangerous.
If I could drop way down in line size I think it would be doable. I want to use a one piece sheet and keep things tidy somehow. That's would be too much wet 3/8 double braid line all over the place. Broken in 1/4" Amsteel is pretty compact.

Not trying to be funny,but what are you trying to do? Perhaps a photo of your boat or a description of the rig would help.

Re: sheets

I think a spectra core line would be OK. But why use it if polyester is strong enough (and cheaper).

Okay, here's a (rhetoriccal) question. How well can you grip 6mm Amsteel with your hands? And how to you plan to cleat it or lock it into a winch's self tailer? The stuff is crazy slippery.
Also, there's Zero break in with Amsteel. And have you worked with it at all? The reason which racers use it are; less weight, & no stretch. But then the sails which they use also don't stretch. And their sheets are usually made of covered Amsteel (Blue), like the line Warpspeed, by Samson.
Using it with Dacron sails is kind of like putting Ferrari tires on a 30yr old estate car (station wagon).

Normally I'm a big advocate of Dyneema, but it has to make sense for the intended application. So what's the thinking here? As it sounds like a case of trying to emulate one's neighbors. AKA Keeping up with the Jones's.

Re: sheets

How much splicing do you do yourself? Because if you can do all your own splicing and have old double braid polyester lines you can remove the core and splice in dyneema cores with the old cover and make warpspeed for a fraction the cost. But if you can't do it yourself it will cost more than just buying it.

As mentioned uncovered dyneema does not work on winches very well, and it will be too small for most deck hardware if you reduce the size to strength match. It is doable, but changing a system over to use uncovered dyneema is a bad idea from a material standpoint and insainly expensive.

Re: sheets

I don't care about the cost. I love to splice stuff, I have all the fid kits.. I think I said in my first post that I would fatten and cover the line. So no ****, you can't grip a 1/4"line made from plastic bags. Is everybody stupid?

Yep, we're all stupid......and you're wondering if jib sheets need to be stretchy.

Re: sheets

If you don't care about cost or doing the work yourself then go with Marlow D12-99 sized to stretch covered where necessary with Samson Flavored Ice covers. Soft shackles made from D12 MAX 99 in the same size as the core works very well to keep the load contained.

Glad the above bill isn't coming out of my wallet!
