I didn't realize until I just looked that Ted Hood designed the Bristol as well as the Little Harbor. No great surprise that I like them both. Congrats your lovely yacht. She sounds like a delight to sail.
I've been told that Dieter Empacher (who worked for Hood) actually did the majority of the design work on these boats but Hood was a much bigger name for marketing purposes.
But yes, they are nice boats. The Hinckley SW42 is a similar design (heavy displacement centerboarder) with similar sailing characteristics-- and of course, with incredible workmanship and a much higher resale value.
Well, the lifting keel puts more weight down lower. The tradeoff is a smaller salon, because the big keel has to go somewhere when lifted. The Southerlys also have a cast iron grounding plate on which the boat sits when it is beached.
For comparison purposes, the Southerly 42RS has 4,630 lbs of internal ballast, and the keel weighs 3,461 pounds, for total ballast of 8,091 lbs. With the keel up, the boat draws less than 3 feet. With the keel down, the boat draws 8' 11". Total weight is 25,003 lbs.
The Bristol 41.1 has 10,500 lbs of ballast, all of it internal. I don't know what the cernterboard weighs, but I'd be surprised if it weighted more than 100 lbs. The Bristol draws 4.5 feet with the board up, and around 10 feet with the board down. Total weight is 26,530.
The Bristol 41.1 is no speed demon, but it is a very nice sailer with an easy motion. Both my friend's 41.1 and my 38.8 will sail themselves with the board down on a close reach and the sails trimmed properly. You can sail for hours in a straight line without even engaging the autopilot.
Southerlys and the Dutch Atlantics do not have centerboards. They have lifting keels, where the keel has significant weight. My Bristol 38.8 is a centerboarder, as are the French Aluminum boats such as the Ovnis and the new Allures models.
