What do you want the boat to do? If you want a pocket cruiser, which will allow you to live and travel on the water for months at a time, go to Alaska, or Bahamas, towed behind a light truck or many SUV's--then the C Dory is a good boat. (Look at some of the recent adventures--two members just spent over a month in AK, going outside of the Islands.) I have spent a month in Alaska and only didn't move one day because of weather--that day, no boats, including 80 footers were moving. One day, I got caught late in the day, and the chop had come up to over 3 feet--I pulled in behind a trawler trying to go 8 knots (actually making close to 6) and had a great ride. Been across the San Francisco Bay when the chop was up--a bit of spray, but a good ride. Run down Johnstone straights in 10 to 15' seas and gale force winds…Boris just came back from the Channel Islands some of the roughest water we have in the S. Calif. area.
A number of C Dorys have done the "Great Loop".
If you want to run out to the outer banks in 4 foot seas, then consider either a Contender or Regulator, with 26 degree dead rise, and some of the disadvantages of this hull type. Another choice would be a catamaran. I have a catamaran for those fishing trips, when I have to make speed, and don't need accommodations when I know it is going to be rough.
Best, look at the C Brat map,
find some one who lives near you , and go for a ride. There is a reason that almost every one of the C Dory's built is still in use, and that the resale value is very high.
There are "tricks" to learning to drive any boat--and the C Dory has several.
Yes, there are a number of folks who knock the semi dory hull. But they have either no ridden in one, or in a boat which was not properly trimmed. Remember that the semi dory is one of the most seaworthy hulls.
