| RI-99-11 0.5 OZ SPINNAKER CLOTH (1999-04-28) |
|
| Q1: | My sailmaker told me about a 0.5 oz spinnaker cloth, that when coated actually weighs 0.75 oz. Is this legal to use? |
| A1: | No. Almost all 0.5 oz spinnakers weigh about .75 when complete, just as most 0.75 oz kites actually weigh 1.0 – 1.1 oz per square yard when finished. The intent of the rules is to use Nylon that’s commonly marketed as 0.75 oz (manufacturer’s quoted ply weight- uncoated). This equates to a minimum finished weight of approx. 42 grams per sq. meter (the same minimum weight spec in the J/24 class rules). To eliminate any confusion, the minimum finished cloth weight will be published in the rules during the next review. [Note: See also revised Rule 6.6 which addresses this issue.] |
