My friend's parents owned a Gemini for many years, and having sailed on it, I found it was a very solid boat. I've also sailed their trimarans in fairly heavy conditions and been pretty impressed by them. I wouldn't get a larger cat than the Catalac or Gemini as they are a bit more difficult to single hand and the costs of maintenance, dockage and such are much higher.
As it is, I'm very happy with my little trimaran.

I prefer the sailing performance of the trimarans over the larger living space provided by catamarans.
AFAIK, the Geminis have never had cored hulls, but I could be wrong. I find it very difficult to believe that anyone could try to do a hull layup without any fiberglass. Even in a cored hull, it is almost impossible to get it to hold together over any large spans without the fiberglass to provide the strength to the resin matrix. A lot of things get distorted over time—and I've found that most stories like that are exaggerations of the actual reality.

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.
