I stumbled aboard a charter Gemini last week in the San Juans. I was curious about them, and liked what I saw.
San Juan Sailing in Bellingham has a couple of them. I think it would absolutely be a good idea for you to charter one, perhaps in October, when the weather is likely to be less than optimal, and see what you think.
P.S. I think you should edit your title to say "Liveaboard" instead of "LA" which might be misinterpreted as Los Angeles. You will likely get more feedback, as is evidenced by the fact that Chuckles hasn't put in his two cents about the Gemini yet...
