In the proposed change do the rules allow a battery to be weight managed in such a way as a skipper could use multiple batteries and ballast them to achieve like weights? Hi Rob What is the lump of lead you might attach to your battery? A corrector weight? (Might be worth keeping in mind that this ...

Entirely legitimate, as far as I can see. It just means you can't move, remove, or replace such a "...

Re: Ok...what is legal?
I can ship or unship "added weight" from within the bottom of a keel stepped mast. But I can't put the weight into the boat as a "corrector weight" when I change rigs. Weights added to the hull must be there for the whole regatta. Hi John Yup, IMHUO, that's it. On my other topic, I think we agree t...

Rob Davis has mentioned on the Windpower forum that RRS E4.7 will disappear from the rule book for 2005.
