Jib Boom

Would a jib boom constuction like this be legal for an IOM?? Taking into consideration that I would use class legal materials.

(I hope Nigel doesn't mind, but scrolling the screen to see everyone's comments was beginning to annoy me. So I've set up the board to allow the HTML 'IMG' tag, and have used this to limit the picture here to a width of 600 pixels, by using the tag as follows: 'img src='http://www.rcsaxxx/uploads/xxxx.JPG" width=600'. Of course, the single quotes must be replaced by the appropriate angle brackets. It still means the board has to download the full 85kb image, but at least I don't have to scroll horizontally...)

Nigel, I don't think it is legal based on the way the rule is currently written. Although the ERS does not specify what a topping lift is, the name itself implies that you are "lifting" something. The forward line in effect controls the same part of the sail (leech), but it is pulling it down, not lifting it up. If you can convince the TC that this is a topper, you're ok. I personally don't think it matters either way, they both do the same thing.

Steve, jep I hadn't considered the wording toppingLIFT. Allthough it could be argued, that this setup is "lifting" the front of the boom

Looked at a couple of sailing dictionaries. In essence, a topping lift is a line that supports the boom when the sail doesn't.

So what do you think, Lester? Would it be a Topping Lift? I'd think not (I'm guessing you do too), since the luff is still supporting that end.

Hi Steve

IMHO it isn't a topping lift, as you say, because the sail is supporting the boom. It'd be interesting to know the correct term for this line! "Reverse topping lift" is a possibility, but doesn't seem quite accurate, since the line isn't supporting the fore end of the boom. Perhaps "Lift preventer"?

I've seen that arrangement on many US One Meters in the USA. I had one on my US One Meter. We always called it a reverse topping lift.

I would say that it's probably illegal on an IOM, since it's effect is to "lower", not "lift" the jib boom.
