Where did you get it from? So far as I know, the design being discussed here is just a prototype (only one or two in existence).james17 said:ive had my clew tie down sleeve for like 5 months now and they're great!
Pretty cool idea! If the ILCA decides to allow this kind of modification, perhaps they could consider wording the rule to allow a range of implementations like JC's and yours.wabbit said:I did some trials the other week with a piece of PVC stormwater pipe [...] People who can tie knots can have just as an effective system as those who can spend money!
There was a resonable discussion (esp. the rules) about the problem of the leading edge of the centerboard wearing a groove in the top/forward area of the centerboard trunk:LooserLu said:And do you understand that about what is now allowed, f.e. with "the problem of centerboard and trunk wear"? Maybe this is also something to discuss deeper in seperate threads - I understand nothing... if I read that words in the report
Murphs said:after talking to the ILCA technical director today (Adam French), the general feeling about the jc sleeve was good apart from the cost issues, he did also mention that they also liked the pvc pipe sleeve instead of aluminium, for cost reasons (i am unsure if they got the pvc pipe idea from 'wabbit' of TLF or not).
another problem is the long term wear on the boom by the sleeve, a test is being conducted to assess if or how much wear the jc sleeve causes on the boom

I would love to see a stainless tie down sleeve introduced to the class because it would make the boat much easier to rig and outhaul adjustment would be improved as well.drLaser said:Hi,
In a post on April 8, I had noted that "JC Tie-down Sleeve", an article about the re-engineered clew tie-down fitting designed by John Christianson was made available in the "Class & Racing Rules" and "Maintenance" sections of the drLaser web site.
Since then, the "JC Tie-down Sleeve" was being tested by ILCA NA Vice Chairman Tracy Usher, and is now on its way to the Worlds at Bitez, Turkey so that the World Council members can have a chance to seriously consider it and test-sail it.
The "JC Tie-down Sleeve" is a cylindrical polished stainless steel part that fits snugly around your boom end and allows you to quickly and securely attach your clew grommet to it. The clew is attached by just hooking it to an internal hook on the sleeve.
The advantages of the system are:
1) allowing you to keep your clew really far down, flat against the boom, giving you a tight leech and thus reducing the load on your vang - a feat impossible with a line tie-down, no matter what kind of line you use, while
2) allowing you to unhook the clew from the boom in a snap, for adverse landing or emergency conditions, and
3) eliminating almost all the friction of the tir-down on the boom.
Those who resist the introduction of this new "gizmo" as a legal Laser part cite that:
1) nobody really needs this (except maybe for hot-shot racers for whom a tight leech is crucial), and
2) a hooked clew can never be as secure as a tied clew, and may accidentally release from the hook in certain deathrolls.
The drLaser article points out that the design is such that it is impossible for the clew grommet to accidentally release from the hook withou human help.
In consideration of the pending World Council review of this new part, it may be interesting to determine if such a new part would have grassroots support. Both the World Council and the designer - a long-time Laserite, himself - would probably want to know if such a part would have a market.
I would appreciate it if you took the poll and voiced your opinions based on the above and/or the (ILCA Members Only) drLaser article.
