I respect your opinion, but must disagree. There has been a West Coast submarine event for many years now, the SF Military Regatta. It was supported by the Mare Island Chapter, and drew a large crowd of submariners from as far as Colorado and Washington. When you say folks have been calling for a sub-only regatta on the West Coast, may I respectfully ask who? Was there a single member out there who looked at this regatta, and said, "I would be there, if only they forbid surface warships from showing up?" Does having a surface warship at an event pollute it? I would think that it would be a welcome bit of ambiance and realism at the least.
Yes, of course the Subcommittee should support the hobby of model submarining. I guess we disagree how to best support it. I feel that exposing the hobby to the maximum number of people would be in it's best interests, as opposed to limiting it to those who have already heard of it. But again, that is just my opinion, and I respect those who disagree with it.
