Excellent Performance
We are building a Solitaire 1520 and she will be a 50' performance catamaran. I based the design off of a Schionning Designs Solitaire 1490 which they claim will do 15-25 knots, but lets take that with a grain of salt. Once we load our semi-custom 1520 for cruising, we will be happy with 8 to 14 knots, averaging 9 over a long passage. This makes her quite a bit faster than the comfort production cats we were originally considering, which only typically sail at a maximum of 8.5 knots and average more like 6.5 knots on a long passage.
