Author: Marcia Subject: Mainsail Cloth Weight Class Restriction? Info: (11936 views) Posted: Saturday 8-7-10 09:40:58 AM |
:: I agree that 16# mainsail weight results in a solid if
:: not overbult fiber laminate. And I like that.
::
:: I bitched and moaned w/the 1st 3DL, and last, I ever
:: bought. Instead of the added fiber weight distributed as
:: structure into the total sail, I ended up with an
:: overbuilt dacron foot patch to make up for the weight.
::
:: Later, I was told, I could have payed more for the added
:: fiber distributed as load paths throughout the sail.
:: Things have improved since 1996.

:: :: The sail weight limit is still in effect. Probably it is
:: :: left over from all-dacron days (to prevent building very
:: :: light sails that would need yearly replacing), but it
:: :: has not been changed and should still be obeyed.
:: ::
:: :: This weight requirement results in very strong laminate
:: :: sails, as they can put a lot of carbon in to meet the
:: :: weight. The local sailmakers all know how to build sails
:: :: to the E27 class rules. It is true that they likely have
:: :: to add materials specifically to meet the rule.
:: ::
:: :: Modifying and/or removing the sail weight limit would
:: :: require a vote at the class meeting.
:: ::
:: :: A few rules have been changed recently and may not be
:: :: updated in the class rules: dyform wire is allowed in
:: :: rigging (even in 1x7 sizes) where 1x19 wire was required
:: :: previously. However dyform is not manufactured anymore
:: :: and hard to find. Spectra is allowed for lifelines as
:: :: long as the sag rule is still obeyed. The remainder of
:: :: the rules are generally accepted without discussion
:: :: (except the crew weight limit), as a general methodology
:: :: to keep costs under control and to keep the boats equal.
:: ::
:: :: If you have any class rule or measurement questions,
:: :: feel free to send them to me directly (not headed to HI
:: :: this summer).
