About the GEMINI 31/3000
The GEMINI 31 was the first of Gemini series of cruising catamarans that became the best selling boat of its type being built in the United States. Loosely Based on the earlier ARISTOCAT 30, designed by Musters and Shaw, the 31 was superseded by the very similar Gemini 3000, which remained in production until 1990, when it was in its turn replaced by the slightly longer Gemini 3200.
