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?

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...
