Sorry never been on a 31, but was told the race
version is faster than the 37' Regarding choppy water
we had a lot of that too. 10 foot steep waves in 17-24 knots full main and full jib
. We were doing about 12-14 knots through the stuff and had to say it felt a bit scary, due to the speed, and wave height, but this is my first time out on the boat so natural to feel a bit on edge. The motion is a lot better than my 46' cat in these conditions but felt more at ease on the 46' cat due to size and weight of the boat. This was just my feeling but an experienced person would know the limitations much more.
The boat is really a rocket ship. As we were heading back I could just make out the Red Buoy, and estimated we will be there in about 10 minutes. Wind
was about 10 knots, then a gust hit went up to 20 knots and we were at the buoy in about 2 minutes. Just flying. The Boat weighed in at 3,500 kg with a big 25hp engine
on it and all goods. Very light and well built. More a Racer
and need 3 people to make sailing fun.
