IOMICA Forum

I have two IOM's and want to exchange sails and trial the boats. One has a groovy mast the other is a 1/2" with metal rings. I have changed the tablings on the groovy mast sail to sail loops made from sail material and attach similar to the tablings with two sided tape but loops go around the mast. The sail material is 15mm in height total not to exceed 10% of luff. In your opinion is this legal? If not what would be.

It is best to start by asking your national Class Association first before you ask on the forum. They should be the first to try to answer the question.

Thanks.

I talked to Steve first and then Lester and was advised to use Nat'l forum then this one because more tech people were on it to get advise /opinions.

Since the loops are not slides, then the 10%max of luff rule isn't relevant I think. What is important is the rule that says luff fittings can't be more than 10mm (G3.3). Your loops at 15mm are probably illegal - thats my COMPLETELY UNOFFICIAL opinion.

Generally, it's easier to exchange the entire rig. Even if one rig is deck stepped, a simple spliced on tube adaptor can be made. My guess is that by using the system described the sails won't behave well on either mast.

Hi, Roy.
That's exactly the way I saw it. If anyone knows about luff rings I DO!!

I suggested that Bill post here not to pass it off to someone else (I did have plenty of discussion regarding this issue), but merely to help Bill find some other opinions (unofficial of course) regarding the subject.
My official position here was to get a drawing or picture of what was intended, and send it to the TC for assistance if it were more than 10mm. I also have concerns what may or may not be a "loop or ring".
