:wink: I agree with Steve's comments in that we can't measure during competition how wet a wet boat is (especially re sails etc.) :idea: Maybe we need to simply say the boat 'needs to be as dry as reasonbly possible'.

OK, lets stick with a case where there is event measurement and later you shift batteries around before the start of the first regata. I think it's wrong because the event 'starts' when? At the preparatory signal of the first race? When you 'sign in' and get your boat measured etc? Is the 'start' of...

While batteries are, in practical terms, inside ballast, they are really part of the RC control system, not ballast per se. As such, the Rules do not currently specify that batteries can not be located at different parts of the hull to match different wind and water conditions. (In at least one USA...

Well done Ken, sounds like you've got it cracked, and not only that, your 'clients' get the correct info to help them stay class and race legal.

Thank goodness for that!!!!

In any case, even if there is a difference, it is likely to be acceptable under App E since you haven't replaced or moved the batteries and as long as you don't fall under the 4kg min wt.

Yes, even if we are talking about 5 grams difference between battery packs, your boat must always be at or above the 4.kg min weight at any time during a regata. Imagine if the boats were dried, as they should be - even worse eh? Out of interest (it's now history) what happened to these boats? Any p...

Rob, can I ask why you find it unfavourable for a sailmaker? The negative comments so far have centered around the cost to the sailmaker of sending all 3 sail sizes for each of the permitted luff attatchments made by the manufacturer (typically, rings, slides and jackstay pocket) = 3 x 3 sails = 9 c...

I am not so sure that that's exactly the case with batteries. Batteries are not counted as ballast, no? In which case they wouldn't fall under E4.7(a). That said, E4.7(b) talks about 'control equipment'. Do batteries fall into this category? - D2.4 says they do. Do event measurers note down the weig...

Whilst I have never completed a hull like that, I did do some tests with various weights of glass cloth and epoxy resin (as opposed to tissue) used with balsa to make a sandwich type hull. The problem I had with balsa is it tended to absorb lots of resin (heavy) so needed to be treated with a sealin...

Steve, I was assuming that the process of 'gap filling' as you suggested had been done below the water already (probably by the builder during keel fitting) but hadn't thought about doing it at the top end.

Rob is right, F3.4 is the critical rule and stays from the spreaders or just below to the chainplates would almost certainly be illegal. It seems that the type of 'checkstays' allowed by the rules would be useful for a deck stepped mast (without ram as IanHB points out) and where the deck and forede...

My point exactly Lester, with the limit imposed by F3.4 I don't think we need further definition.
