Hi all,
So I tapered a set of spinny sheets up the other weekend but was unsure of how to best attach them so I went with 2 bowlines in the end for security reasons. I was wondering if anyone knew a better way to attach them because I found the 2 bowlines liked to catch around the front during gybes. Any ideas? |

Take the end through the cringle at corner of spinny sheet and then take the end around and through again. Put a figure of eight knot in the end and pull everything tight. Do the same on the other corner.
Also if it is catching at the front (the jib wire?) Then you need to improve your gybing so that the Spinny floats out in front of the boat as you go through the gybe. ------------- Merlin Rocket 3609 |

| Personally I take the sheets through the cringle and tie a half hitch round the oppsite sheet - a fisherman's knot with the clew in the middle... |

Your method would work for an asymmetric spinnie (or for attaching jib sheets) while mine works for a symmetric spinnaker. I wonder which type he has? ------------- Merlin Rocket 3609 |

Reading the OP; sounds like an asymmetric. For my symmetric I was told a blindingly simple method that I was very unsure of, but to date they have never come undone. Put a plain overhand knot in the end of the sheet, thread through the clew and then simply do an overhand back round the sheet pulling it tight to the stopper knot in the end. Very low profile and always the same length so your settings are the same every time you rig.

Your way works but mine seems to get the corner of the Spinny tighter into the end of the pole when the downhaul is pulled on. Agree that original poster probably has an asymmetric. ------------- Merlin Rocket 3609 |

Reading yours again Time Lord, I'm liking it. You use the figure eight to stop tight to the cringle, right? I'll give it a tinker next time.

Correct and I am not claiming it as mine as it was shown to me by a merlin supercrew. ------------- Merlin Rocket 3609 |

I tapered mine the other way, with the thin bit in the middle, tying the fatter ends together in the boat. Then splice an extra bit of string into the centrepoint of the tapered part to give a short tail and bowline that to the asymmetric. Even if you do run the sheet across the forestay on a gybe, there is nothing to catch. Jobs a good 'un.

I spliced my kite sheets together where they attach to the kite so I only have one knot, the effectively continuous piece of rope goes around the forestay much easier. I then put a simple link in the other middle of the sheets so I could get them on and off the boat.

that.... although I just centred the sheet and took a couple of inches and spliced them together with some whipping twine. Then larks head the cringle...

Hi
A quick tip When you bury the cover in to the core you can wrap the tapered cover bury with white electrical tape so that the bits of cover don't poke through the core. It gives a neat finish. |

Topsail sheet bend. A classic knot - a variant of a figure of eight. http://www.google.ie/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&docid=_bBOxSx2YI_-jM&tbnid=ZDJ9553zqMkt7M:&ved=0CAUQjRw&url=http%3A%2F%2Fwww.thecheappages.com%2Fboat%2Fmatl%2Fknots.html&ei=l3iwU6nuIq2e7AahlYCABA&bvm=bv.69837884,d.ZGU&psig=AFQjCNFv0w1NztrBnqv-y5AaFxqr5kpVng&ust=1404160531475827 ------------- Gordon |

I made some for the 200, similar to both Neptune & Fab100's, but
I pulled a 4" loop of the Dyneema core through the cover in the centre point of the rope, which I sewed & whipped in place. I also tapered 4" both ends, with a burnt overhand knot at the ends of the Dyneema.
The loop pokes through the clew then the whole length passes through the loop. The tapered ends tie neatly together in the boat with a small knot that doesn't jiggle undone.
I do like Neptunes loop & tie idea for the ends. Didn't think of that.

Just incase anyone is interested in tapered sheets for their boat I have some excel on order and enough material to make a few more
Let me know the lengths and specifications... |
