The current class rules read as follows, so my feeling is currently it is not permitted as the trapeze elastic takeaway point on the wing is limited as follows.
Happy to review this in the sailor survey if the members wanted...
(1) The trapeze system, handle and ring are unrestricted. Combined or linked systems are prohibited.
Except that the trapeze elastic takeaway point on the wing is limited to:
(i) An exit hole within the wing at a point 845mm aft of the front of the wing.
(ii) From the s/s becket supplied for the kicking strap and cunningham take up pulleys
(iii) An additional position using an s/s becket a maximum of 290mm aft of the front of the wing.
(2) Where the trapeze elastic is led externally as in (ii) and (iii) above, a substitute elastic shall be fitted from the plastic wing end plug to the becket located next to the forestay bridge.

Interested hear from Chris as I'm a bit concerned, an earlier adopter than me suggested he'd given approval
I'd rather not end up during a second set of trapeze elastic for light winds.... Alternatively we could have a minimum of 7kn rule instead on 5

Or you loop the elastic round the front of the wing in light airs

The elastic wears out fast enough being tortured through the range of positions that come out of that wing eyelet, wrapping it around the front of the wing, or even a 180 degree wrap to a clip on the kicker take off can't help that surely

Putting round the wing end just gets it out of the way in light airs.
Chris will be able to confirm, but my reading of the current rules is that the trapeze system is open apart from the connection points to the wing, so I'd assume you could add a swivel block or an aluminium ferrel on a line or similar to help directional wear on the two alternate positions?

Hi Mark sorry for the late reply but I have been away. The idea looks great and very simple but before I comment on its legality, I would like to chat with the technical committee if that's ok. I will come back to you soon

Of course, thanks Chris. Let me know if you need any more info.

Hi Chris, any news about the pimp?

I've been in touch with the technical committee and they feel the two ideas on this thread are currently illegal.
However, the technical committee are putting a rule amendment forward for the annual survey that, if accepted by the class, would permit attachment methods such as these. It was generally agreed that both ideas were very good and the class should always consider new ideas.

I was told by Chris at the 2013 highcliffe nationals that this pimp was perfectly legal provided that;
-only shockord (yes d12 qualifies as shock-cord), bobbles and rings were used
-that a piece of shock-cord was lead from the rack to the bow for aesthetic reasons
This pimp is simple, cheap and harms no-one.

Regarding the trapeze systems, Paul has stated above that the technical committee now feel that some systems are not legal but a good idea and will include them in the sailor survey for the class to decide if they want to adopt. In respect of D12 being shock cord, the definition is strands of elastic with an outer covering, and D12 does not fall into this spec so is definitely not legal in place of true shock cord.

That rule amendment didn't really offer anything. The wording was presented such that it was effectively exactly the same.

Hi Mark
Interesting observation, I'd say it mades a big difference...
Why do you feel the proposed new wording makes no difference?

Can you post new and old wording here please as I'm not sure I can get back into survey.
