[Public-List] Knockdown in an Alberg 30

[John Birch]

Your chances of being rolled on the Great Lakes is very small and only in 
shoaling waters, where I did see video of a C&C being rolled at a Harbour 
Mouth in a gale in Michigan. However the chances are remote.

There is no such thing as a roll proof rig as hydrodynamic forces are almost 
impossible to predict under real world dynamic conditions. If the sails are 
up few rigs will survive - Gypsy Moth was rolled with her sails up in the 
Southern Ocean and the rigs did not come down, but that is more likely plain 
luck.

Simply reinforce everything, particularly chain plates and go sailing.

You have a better chance of being struck by lightening

Best
