I dont know how much they cost but here goes, I am sure there are many more I'd trust but this is off the top of my head
, sorry these are US boats.
Tartan 37 and bigger
Pacific Seacrafts (any size
the big characteristic I like is a
1) has a nice seakindly movement. (most important to me)
2) glassed in keel
( you said long hard storm, I'd worry about keel
3) ports/hatches not too big (breaking waves love big ports)
I think the key is not to get into the bad stuff but I agree to be prepared.
Have fun, great queston.
