David Thanks for the drawings. They're very helpful. I have a much better understanding of CR F.3.3(c)(2) Would you agree that separating pivot and attachment points for boom, and pivot & attachment points for kicking strap, by several millimeters of carbon plate makes these points no longer adjacen...

David, could you clarify these statements please. " F.3.3(c) (2) The mainsail boom spar and the kicking strap pivot points shall be aft of the mast spar in the regions adjacent to these points. Examine F.3.3(c) (2) In particular the passage ‘in the regions adjacent to these points.’ This does not re...

David In an attempt to address this statement, "So perhaps someone could explain how, even within a closed rule, could this small band of experts might have concluded that this particular type of gooseneck fitting is non-compliant with any part of the relevant Class Rules. And that there was any nec...

Hi Dave This is only my personal opinion, nothing official. One thing the plate GN does is take the attachment point of the mandatory kicking strap fitting F.3.3(a)(4), and the optional mainsail GN fitting F.4.3(b)(2) and move them aft of the GN vertical axis of rotation. This is not specifically pe...

Gentlemen, perhaps a compromise is possible. IOM ICA Regulation 4.11. says: 4.11. At any World Council meeting only resolutions of which notice has been given in accordance with these Regulations shall be proposed and no amendments thereto shall be permitted, unless the proposers of the resolution a...

Just want to say a big Thank You to the production team of Kaleu Wildner and Rick Francesconi, and to Hanneke Gillissen for the great job they did shooting and posting the photos and video for the 2015 Foster City IOM Worlds. Very professional... well done all. Here's a link to Rick and Kaleu's wrap...

Hi Gordon I have a question. When “and as a result retiring” is removed from RRS E6.6(f), how does that effect RRS E4.3(c) Taking A Penalty ? RRS E4.3 Taking A Penalty (c) if the boat caused serious damage, or as a result of breaking a rule of Part 2 she caused another boat to become disabled and re...

Hi James.

Is there any reason that this arrangement would fall outside of the class rules?

Maybe... does any of it work in compression ?

This is a good servo for the price.
Dual ball bearing, metal gears, enough torque.

Richard, thanks for the explanation.
Cheers

I see. Thanks for the info Barry.
Does anybody know when this election takes place ?

Hi Lester It's always good to hear that there are people willing to put in time and effort toward the various organizations involved with radio sailing. With respect to IRSA, how does the election process work ? Who gets to vote ? Does one have to be a registered member of one of the 4 International...

Are there any resolutions for the class members to vote on this time around ?

There is also some good background information in the "History Of The IOM Class Rules" on the IOMICA home page > Class Rules page (link is at the bottom of the page).

Here's a link : http://www.iomclass.org/doc-files/Techn ... 231110.pdf

Hi John, looking at the wording of the interpretation I don't see any need for an amending the CR. "a)Single panel sails are permissible under the Class Rules and that b)The use of a mould to allow, by the application of heat and/or force, the sail material to conform to the mould shape is not prev...

A nice article from Bruce Kirby

Laser designer and Int 14 sailor pays tribute to Geoff Smale

http://www.sail-world.com/USA/Laser-des ... male/82434

I met Geoff at the Vancouver Worlds. He was very friendly, and interesting to talk to. He had several innovative parts on his rig that he was happy to show me, and explain the thought behind them. At 30 years my senior, he was a far better sailor than I'll ever be. My condolences to his friends and ...

Hi Andy. Please clarify. First, what is the "agreement between IOMICA and the RSD" ? Is there a document somewhere on this site, or the RSD site explaning the agreement? Second, by "not condone action that goes against the agreement....", do you mean that you feel the RSD (and the RSD PC) is still i...

<< The rules only apply while racing.... Racing is what happens between the prep signal and clearing the finish line. 'The rules of Part II only apply while racing'. The whole of Part II. >> Uhh.... not quite. The rules limiting the replacement of appendages (C.6.2), rigs (C.7.1) and sails (C.8.2) ...

I think the rules work fine here. It's another one of those areas where there are tradeoffs. If you go to big adjustment holes to lose boom weight, you're going to have coarser adjustment. You could overcome that with transmitter adjustment, but why bother. In my opinion, finer adjustment (smaller h...

F.4 BOOMS
F.4.2 CONSTRUCTION
The spar section shall be constant......

It was explained to me that the word "constant" in F.4.2 means no lightning holes.

Paragraph 2 of the Introduction to the IOM Class Rules states: “The rules in Part II and III are closed class rules which means that anything not specifically permitted is prohibitedâ€

Quoting Lester: << This seems to tell me that a promoted boat does not finish racing until she finishes her last heat. >> I wholehartedly agree with this interpretation of E1.1 I would go a step further, and say that E1.1 also establishes the fundamental principal on which HMS is based; namely, a ra...

Hi Lester. With all due respect, I would disagree with this statement: << If you are currently in E heat, for example, and gain promotion to D heat, you are still 'racing' between the end of E and the start of D, and so you cannot change or move your batteries. >> Still racing or not, the way I inte...

My experience has been : 6061 T-6 will bend pretty easily. You can get a nice curve in a 6061 mast. Don't try to bend a 7075 T-9 Easton mast. Chances are pretty good it will snap well before you can get a significant amount of pre bend into it. The 7075 Easton sections should be plenty stiff enough ...

OK... I'll buy that.

Maybe I'm the one who's density needs to be examined, but something doesn't seem right to me. The rule in question says corrector weights placed above the lower measurement point must be of a density greater than 8 Kg/cubic meter. That's about 17.6 lbs for a cube roughly 39" X 39" X 39"... right ? T...

Ah yes... one of my favorite interpretations. http://www.radiosailing.org/pdf/Interpretation%202003-IOM-4.pdf Thank God those 3 gnats that wound up in my hull layup weren't deemed to be additional crew members. The "filler" interpretation is a very good example of the ambiguous language and convolut...
