Cruising Catamarans Offshore

Hi thor

I don''t dislike cats (only the fat ugly ones).
Fact is that three years ago I was even considering buying a Tri, one of those fast things that flirt with 20 knots of speed. I didn''t buy it cause it was a lot more expensive and marina costs were 1,5 higher. It was also a bit small for the family.

I posted the link to that paper because it is a superb study in catamaran stability, I have learned a lot with it and I thought It would be nice to share it.

And Thor, obviously it is impossible to capsize a modern cruiser monohull sail boat only by wind force (no waves). All of them have an AVS of more than 110,most of them between 120 and 130 and a downflooding angle superior to 100.

The boat can lie flat on the hull (90) driven by wind force, but at this position the wind is not making any force on the sails (passing over them), so the boat will rise up again without capsizing.
