]B.4.1.4. Maximum Upper width at upper leech point 1500 mm from head point : 1290 mm
B.4.1.4 & B.4.1.5: Sails with larger measurements can be measured and used until 01.01.2009.
Does this mean the max width of the sail at 1.5m from the top of the mast shall be 1.29m ? I hope not! <img src=

Hey Dazz, both yor big mains are measured. Surley they will grandfather any mains measured prior to the date. Does not read that way though.
I understand that there is no
grandfather
period. The date is a cut-off and has been out for a while. I think most F18 sail makers knew of the cut-off date and have been making 2008 sails to the new measurement.
does this mean that my 2 sails I have are not f-18 legal? Standard h tiger stx mains?
Hobie Class legal, yes - at least I haven't heard there is a corresponding rule change proposed.
F18 legal? Not sure - you'll have to pull out the tape measure and check. The new rule was raised in late '06 or early '07 (I'm told) to address a trend in fatter and fatter heads on mains. You very well may not have an issue. This sort of thing may have eventually self-limited through trial by the fleet, but a rule was passed anyway. The intent, like most F18 rules, is to keep some grip on development and forced obsolescence.

Sail Measurements. There was considerable discussion on limiting sail head (H1) size, but sail makers pointed out that this was easy to abuse IF they wanted to. A further meeting outside the Technical Committee of Messers Vink, Goodall, Tanguy, Boulogne, Bernitez and Findlay has agreed that the
H1 measurement should be limited to 1000mm or thereabouts and a further measurement should be taken on the leech with a “swinging arc, 1 m 50 cms from the uppermost part of the head point, this measurement would then be taken horizontally back to the bolt rope. The small group would discuss and refine this matter before the end of the Hyeres regatta. (Don Findlay called Pablo Soldano on this matter and he thought this was a sensible way forward) This should make further foot measurements obsolete. [color:

May get away with it, just depend how far down the leech 1.5m goes!
Ah okay that's better. Measuring down 1.5 m from the head then horizontally from the luff to the leach put my main way out of legal. I suspect the swing measurement is going to be a bit different.
Well this is a bit disappointing. I have two mains that don't measure under the new rule. one I could not care less about and the other is like new.
worst part is goodall was on the committee and he produced the sail after agreeing to the new rule.
Goodall did not produce either of those 2 sails. They are 2006 built sails made by Steve Brewin for the AUS Worlds. They were class legal, very fast and quiet popular. I had elected not to use that second main and save it for major events as the 1160 sail was looking at retiring to a club sail.
Very disapointing that main will soon be illegal in the F18s. Put it aside for the Capricorn events as it should still be legal for that.
Err.. I don't think there is a Cap
Class
with it's own rules. In the US, all Caps and Infusions are under the F18 rules - only the Tigers maintain a separate
one-design
set of rules.
For all the Tiger owners - our stock 2008 Hobie STX Smoke mainsail was measured at 1275 mm.
WELCOME to the Website of the TAIPAN and CAPRICORN CATAMARAN ASSOCIATION OF AUSTRALIA (TCCAA)
My sails are 40mm over, im looking at options to fix it.
now this is interesting..
B.4.1.3. The aft head point of the mainsail shall not be
above the head point.
what is the definition of a head point? is it the grommet in the head of the sail?
For the definition of Head Point and Aft Head Point, see diagram C.4.1 in the rules. The Head Point is not at the grommet.
Drop a note to Greg Goodall - I understand he trimmed that 40mm off of several sails recently.
OK I went out and measured the Infusion main and I came up with just under 1000mm for the top head to lech measurement. I took my tape and hooked it on the bolt rope at the head and measured to a point 1500mm at the lech (the tape was at an angle). Then I measured from that point on the lech 90 deg to the bolt rope and that was just under 1290mm. If I did it right the Infusion main is good to go for 2009.
Dazz,
contact Steve, I chatted with him about this topic a few months ago when the issue turned up on some of his sails being measured for the last worlds. I'm sure a solution is easy (removing some area) but you should give him the opportunity to advise on the best way to do it.
Got hold a return email from AHPC today. $45 for an alteration to the sail to bring it within the rules. +freight. not bad i thought.
That's about $532 USD, but like you said, it is a good deal. <img src=

I also measured my Infusion sail using the swing measurement and it appears to measure in. I took some pictures and I'm waiting on validation of the process I used, once I get the okay I'll post the pictures.
