Heh. Yeah.
You can go read bluewaterboats.org. Most of the boats there tend to be heavy displacement traditional/conservative designs with a long keel or moderate fin + skeg rudder. That would fit with Coles' book Heavy Weather Sailing, where Olin Stephens basically calls for moderate design and heavy construction.
There are others who swear by newer and much lighter designs, of course with lots of debate about which boats really merit trust. A high-aspect-ratio fin with a bulb can provide an impressive righting moment - on the other hand, a Farr-designed First 40.7 called Cheeki Rafiki just lost its keel and its crew in a nasty N. Atlantic storm. Lots of racers on Olsons would take them anywhere. Go read Paulo (PCP)'s Interesting Sailboats thread. The Europeans, especially the French have been very into this stuff - Pogo.
Yet another interesting French approach is the shallow-draft centerboard boats, which Alubat/Ovni has been doing for years. I just read about a guy who took a new Boreal 44 into some very nasty stuff and loves it. Aluminum boats with all-welded deck fittings = no leaks. They are relatively fast, he was posting 200+ mile days with slowing down at night, though not like a Pogo can do running full-out.
Again, JeffH has written some excellent posts about these questions. Google is your friend.
