While in the Caribe we saw a few gemini's and tons of FP's. The narrow width of the Gemini will make a bit rollier compared to the wider FP, but still much better than a mono anyday. In the states the Gemini has the advantage of being able to fit into most standard slips.
When looking at the cat's bridge
deck is a concern. Makai has a low relatively low
deck for an ocean going cat and is a bit noisier in the heavy
weather, but the lower bridge deck and the design allows us to sail upwind at about 35 apparent and maintain good speed. We generally sail inside and faster than most of on mono friends and all of our cat friends. It is a
trade off, just be sure of the design and the
builder when selecting.
