Hi guys, ready for a new lesson of "ISO for Dummies" ???
Yesterday I saw a musto skiff, and I really liked the way the kite sheet was attached to the kite itself:
in the middle of the sheet there was a splice, with 10-15 inches of a small diameter dynema going to the kite.
(see http://www.moncia.it/sail/Kite_sheet.jpg).
The main reason for doing so looks keeping the kite away form the shroud, while only the sheets touches it, while coming about.
I'd like to know:
1) if ths is allowed by class rules
2) Did anyone try this on ISOs ? any tips ?
3) Is it permitted on the Jib sheet as well ?

I was quite interested in mmonica's post, I have assumed that the ends of the kite sheet are threaded through the clew, with a figure of 8 knot to stop them pulling through, monica's post suggests to me that the middle of the sheet is attached to the kite with the floating ends passing through the cleats and stopped - what is the recommended method ? I have also attached the jib sheets this way, is this correct ?
As a newcomer to the ISO I found the tuning guides very useful - many thanks. |

Hi Rob,
The way you assumed is how I do it although I have always used bowlines instead of stopper knots.
I have seen the other way round (as mmonica's post) recommended (with variations for attachment to clew s.a. a small shackle tied on to the sheet). It is supposed to help the clew go round the front easier in a gybe. You end up with a knot to tie the ends together in the middle of the boat. This is ok except I don't know if it would work with the spinnaker sheet take up system (as per web-site tips) which I have just implemented (and works brilliantly btw).
Re Jib. Most people attach the jib the way you have (continuous). For many years I rigged it the other way round (mid-point through clew with stopper either side) and tie the tails to the elastic at the trapeze rings. The advantage of this is that the crew can always get to the sheet. More experienced crews may find it just gets in the way of hooking on and off but it might be worth experimenting with. We are trying the continuous way again at the moment but not sure we like it. |

The technique you mention Marco is very good so to allow the kite not to catch on the forestay. The Laser 5000 fleet use this technique as it is important for the kite not to snag when pulling the kite round the forestay for a windward drop (Spinnaker bags for those not aware). Also used by many single handed skiffs (Musto Skiff, RS700 etc)
This technique in the ISO does however prevent you from using the take up system that a lot of us have adopted (in the ISO tweaks section).
My personal opinion is to go for the take up system and I am sure a lot of others will also support this. I have found that 3 ropes in the bottom of the boat always get tangled. Two hardly ever, One - Never!?
The 3 ropes in question are:
- Kite sheets
- Kite halyard
- Jib sheets
One take up in use is for the kite sheets.
Two take ups = one for the kite sheets, the other for the spin halyard. leaving just the jib sheet in the cockpit.
Hope this helps. I do have a lot of new photo's for the ISO tweaks section, but college homework prevents me from processing them till July time.

thanks for your repies.
I'm not sure I fully understood why I cannot use the take up system...
I was thinking about splicing the kite sheet together, to allow the take up system take them away while the kite is up...
ok course at the other end (in the middle of the sheet, where you attach the small rope) you must have a free end to attach to the clew (with a knot or a small plastic ball as used on the main halyhard)
I'll probably try and let you know ...
bye

You cannot use the take up system if you tie the ends in the middle of the boat - if you splice them then you are ok! The knot catches on the plastic ring take up and can cause problems.
I would attach the sail to the little bit of rope on the sheet with a small shackle.

Thanks for all the feedback; lots of food for thought !!
I think we will be trying a few variations to the knitting as the kite doesn't seem to want to go round the jib luff very easily ( although this is probably inexperience !!!! )
Now we have got past the abject fear stage, the boat is brilliant, and so much faster than anything else we have sailed - lots of adrenalin !

Not sure if you are aware Rob, but there are 5 or 6 ISO's at Glossop & District SC.
