I've previously made a brummel eye splice from 3mm dynema, then instead of burying a tail like  I take the two ends and feed one in each direction within the core of the sheet, milking back over the cover. Then a few stitches and whipping to hold in place. It seems to work well. The sheet then cow hitches to the clew and ends are tied in the boat. I'm not sure if the tail of a brummel is really designed to be loaded in this way, but it seems to work. The downside it you're left with quite a thick bit of rope by the clew, where you want it lightest. 

I've come across this video by rooster, which I've done on the 800 kite sheets as it's much simpler. But is it as strong? I fear if the cow hitch slipped it would slide back, stripping the outer from the core as it moved. Is that a real risk though? 


What I'd really like for the kite sheets on the 200 is a taper about 0.5 meter from where it attaches to the clew via loop which cow hitches. Could just strip the outer and then do a locking brummel in the middle, but instead of one tail of teh brummel being burried, it's taken away and becomes one of the sheets? Are brummels really designed to be loaded from two directions? 

Or should I taper both my sheets and eye splice them to a soft shackle which attaches to the clew? This would save having a knot in boat, but I'm not sure it would go around teh forestay as smooth!

Recommendations and your experiences please!

On our 800 and 29er we taper the sheets and put an eyesplice in the ends. Then use a 'luggage tag'to attach to clew. The luggage tag is a piece of vectran with an eyesplice on one end. Pass the eye of the vectran through the sheet eyes and then the free end of the vectran back through its own eye. Then bowline onto the clew.

Absolutely no snagging on the forestay. Best bit of bimbling we have done.

Got any pictures?

Luggage tag is another term for a cow hitch, is it not? Sounds a decent solution for the kite but I don't like knots generally and especially in the jib as they throw off the calibration whipped in to the sheets. 

If I go for tapered sheets with eye splices I'd use a soft shackle for clew attachment. It give more consistent sheet length and is impossible to incorrectly fasten in  panic. 

But I'd rather luggage tag / cow hitch with a loop straight on to the clew eye.

This is what I have currently. A brummel splice (locked) where the two tails lead in to the sheet in either direction. 



I think it's better than the rooster video, as there all the load is always on one tail of the cow hitch, so it can slip. Whereas with this, the eye splice makes sure there is always equal load on each tail of the cow hitch, no matter which tack. So it can't slip. There is basically no way it can move or come undone, and it takes a second to rig. It also always fixes exactly the same meaning the jib calibration is always exact. 

The downside for kite sheets is that it's quite heavy. Do you think the above can be replicated, but with the outer core removed? Or just stripping an outer core, then putting a brummel locked eye splice mid line?

Is this for the 800 or the 200 Tom?

200 jib and kite. 

800 I've done as the rooster video above. It seems to hold okay, but it seems like a 'cheats way' of creating a centre take off.  The cow hitch is always loaded form one side, and dynema is slippy, so it doesn't fill me with confidence. I may put a bit of whipping around the loop on the 800 kite sheets to transfer some some load to the other side of the cow hitch.

Light weight/ quick to make/only need a needle fid/ impossible to come undone/nothing to snag or catch if pulled tight enough/strong enough to have not broken before the kite sheet becomes a cube from the ratchet and gets replaced anyway

Thanks for all the suggestions!

I went for tapered kite sheets (red) ended with two locking splice on a soft shackle, no knot in the boat. If the jewel knot in the soft shackle gets hung up on stuff I may change to the eye splice and bowline mentioned up thread

Then jib sheet I went for a centre take off loop to attach directly with cow hitch / luggage tag (yellow). I went for the Rooster method of just pulling out a loop of core and stitching in place, I put a bit of whipping which should keep enough tension on the slack side of cow hitch to stop it slipping.
