Default Which boat is most likely to capsize ?

TAYANA VANCOUVER 460 PILOT
Angle of vanishing stability = 110 degrees
Ballast/displacement = 0.24
Capsize screening ratio = 1.57

BENETEAU 473
Angle of vanishing stability = 119 degrees
Ballast/displacement = 0.34
Capsize screening ratio = 1.96

CATALINA 42 MARK II
Angle of vanishing stability = 105 degrees
Ballast/displacement = 0.39
Capsize screening ratio = 1.97

Based on those numbers (which are highly theoretical);
The Tayana will be a bit have a more comfortable motion but most possible of
capsize and slower to recover.
The Catalina will be stiffer and harder to turn over, may turn turtle in a
major knock down but faster to recover.
The Beneteau will be between on comfort and can handle a more severe knock
down but will recover slower than the Catalina and faster than the Tayana.

You need to get over the buy now fever and invest in a few books. .

Boy are you out to lunch.

The Tayana is most stable indicated by the capsize factor. (The lower
the better) The Catalina is least stable.

There are no comfort figures here but the can be worked out at:

I think the Tayana with the pilothouse will recover very fast.
