Asymmetric Spinnaker Sheet Length

As I mentioned in an earlier Tip, we just bought new spinnaker sheets at not inconsiderable expense. Here’s why.

My previous boat, a Luffe 40.04, had a line from the clue that was permanently attached. This line was about 3 meters of so and ended with a loop where we could attach the sheet with a snap shackle. We used to sail with only one sheet attached on the lee side. When gybing, the mentioned loop was close enough to reach so that we could attach the new sheet and let the working sheet go (using the snap shackle). I found this a good method. Perhaps the shackle can be dangerous if whipping around, but we never had that problem (mostly sailing in calm waters).

Cheers and thanks for a great forum.

Hi John,
I think there are pros and cons. It makes it simpler and faster to manage only one sheet instead of two (I’m always a bit concerned one could go under the boat). On the downside you’ll have to go up on deck to release the snap shackle. We use it sailing two handed. Perhaps not such a good idea for single handed.

Hi John,

Point taken. The headsail wrap hasn’t happened to me yet when jibing, but of course it could and I agree it is not very pleasant (an article on how to get out of a headsail wrap situation would be interesting).

I enjoyed reading about the rhino horn or batten. I’ll try that on my new boat (a 55ft aluminum built Bermudan cutter).

Poor man’s spinnaker net
A couple of thoughts on spinnaker/asym use.
The most likely, almost predictable, times I have gotten headsail wraps were in light air and swells/wakes. The swell/wake gets the boat rolling and the asym collapses around the headstay (the light air keeps the asym from being well behaved). The continued rolling serves to tighten and extend the wrap: a real mess.
A friend suggested what he called a “poor man’s spinnaker net” and it is simple and easy.
I unroll the jib 6-8 feet and sheet it hard amidships (more effective with a higher clewed jib topsail than a low clewed genoa): a poor and lazy man’s spinnaker net. The extended sail and the sheets interfere some with getting the wrap in the first place, but excel in keeping the wrap from being tightly wound around the rolled-up jib. If the wrap occurs, the wrap is far easier to loosen: and, one can roll in or out the jib a bit to ease tightness and facilitate loosening and freeing the wrap.
The other “hack” is to have high modulus sheets: not so much for their strength than for their not soaking up water and becoming quite heavy. In light air, the sheets will occasionally dip into the water. Dacron sheets soak up water like a sponge and will become heavy enough to drag the sail out of shape in light air.
My best, Dick Stevenson, s/v Alchemy

Hi Dick,
Many thanks for sharing. Sounds like a good method in light air and swell.
Best regards,
Christian

Hi Dick
That seems such an obvious solution. No wonder I didn’t think of it.
My days of spinnaker wraps are thankfully in the past but I recently managed to wrap the, new to me, furled Code Zero or what thought was a furled Code Zero around the furled Yankee.

What diameter and material are the sheets?

The Poor Man’s spinaker net is interesting. I have always wondered why spinaker nets ate not more common, particularly on short handed boats.

Hi Carl,
Now that you mention it, I believe the first I heard of this spinnaker net hack, it was called a single-hander’s spinnaker net. Dick
