Right guys...me and a friend have got hold of a nice cheap Laser 5K. We are fine with sailing it, and want to get into racing it more, with a bit of fine tuning needed, so therefore i put a few questions to all you other asymmetric sailors.

How do you attach your spinnaker sheets? (i know there is the classic bowline, but with bagging the 5k spinnaker the knots get caught on the forestay)

I have thought about splicing both ends of the sheet in various ways (http://www.apsltd.com/images/CATEGORY/medium/1558.jpg or http://www.apsltd.com/images/CATEGORY/medium/1557.jpg) or pulling out and stitching a loop of core in the middle. How strong would a stitched loop be (bearing in mind sheet loads on a 5 arent light)?

Is Holmenkol sealnglide really worth it and make a difference? A whole 35 can will just about do a single spinnaker I believe?

Cheers for your views guys

find the middle of the sheet, make a bend, push this bend through the clew eye on the spinnasker, pull the rest of the sheet through the loop you have created, pull tight, feed the sheets through the various blocks, and tie the two ends together securely.

that way the knot is IN the boat, not ON the spinnaker

Yeh, I thought about doing a larks head (or whatever you will call it) onto it, but im still concerned that this will get caught when pulling the kite down to windward, and also that i may never be able to undo it again after a big breeze.

We have it like that on our 4000. Never been a problem.

Does that mean that outings in your 600 are going to be
even rarer on the circuit now Oli?

run sheet through the clew eye and put a half hitch round the opposite sheet. Tape round and across the clew to make it even less snaggy.

We goa bit further- find the middle of the sheet, and pull a short section of the core out through the cover. Stich to hold this loop in place. Stick the loop through the eyelet, and put the tails through the loop. We have a webbing eye, which makes getting it undone a bit of a pain.

This is what I used to do, and how i do when i am setting a boat up for teaching, however i have had it pull through the clew, making it impossible to fly.

This is more along the lines of what i was thinking, but im worried the core may break the stitching and pull out a large length.

Has no one any experience with Holmenkol or any similar products?

Following what Al said - find the centre of the sheet; pull a bit of the core out and splice a thin piece of spectra (or similar) about 150mm long into the core.  Push the core back into the outer to make it look neat.  Attach the clew using the thin spectra - the sheet then has a smooth surface to go around the forestay on drops and gybes.

Holmenkohl really works well on B14 kites - it doesn't recover the fresh crackly kite feel, but it does make the cloth shed water and very slippy around the forestay.  I easily covered two kites with a single 30 bottle.  I was very sceptical when I first tried it, but it is easy to apply, really works and lasts a long time - in fact my favourite kite is the oldest one I have - made good with holmenkohl.  Expensive - but good value
