Ratings run around 180 secs/mi. That's about an average for a 35' coastal cruising monohull. It looks like you get more space/volume in the Gemini which must slow it down(weight).

On the other hand, an even smaller tri is much faster with phrfs about half or less, similar to say a J35. But you get pretty spare accommodation/ length in comparison.

So for speed, commodious interior, you need a bigger cat than the Gemini or a larger tri? Longer is still the best tool to go fast and carry accommodation space.
