Gemini 105C

Ok folks, I like the room of a Cat but I don't like the PHRF rating of this one. I've not sailed a multihull but have heard of issues with pointing with Cats. I understand it's likely to be the size of the house that determines this but was curious as to how well the Gemini 105C / MC goes to windward. Also, what are the performance specs for this boat in say 10-15 true?

You might want to contact Sue over at Performance Cruising, as she might have some polar diagrams for the Gemini. There is a website about the gemini 105 that one owner put up that you might find of interest. It is located here. While I've had some experience with the Geminis, I couldn't really say how well they go to windward in a pinch. The polars would really give you all the information you want.

BTW, most cruising catamarans aren't going to get a stellar PHRF rating, since they aren't geared towards speed in general. And many cats do have a pointing issue, but that is generally more the case with the stub keel-no board designs than it is with the daggerboard/centerboard equipped boats. They also can have a problem tacking, due to the excessive windage caused by the high freeboard many cats have. Neither of these criticisms are geared towards the Gemini 105 in particular but are more blanket statements about catamarans in general.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
