Narrowing it down
There are a number of problems with mid cockpit designs until you get to a boat somewhere over 40 feet. In order to make a midships cockpit work, you end up using up a lot of prime real estate, in other words the cockpit ends up in the widest part of the boat,the part of the boat most likely to have good headroom without a lot of top hamper, and the part of the boat that has the best motion from down below. With this areas used up by the cockpit and passages it is harder to develop a design that places key functions in less than ideal locations and tends to result in a boat with a lot of windage, a high vertical center of gravity, and higher weight. In order to get past the cockpit a lot of key storage areas are used up in circulation. In a boat less than 40 or so it means that the cockpit is raised significantly causing greater apparent roll accellerations.
Once you get over 40 feet, with 42 being far more ideal, then it is easier to make a center cockpit work well. The criticisms of the smaller CC boat are still valid but are less significant.
The keel/skeg hung rudder vs post hung or transom hung rudder debate will probably be eternal. Boats with post hung rudders have made many circumnavigations. The keel stepped vs decked stepped mast comes down to execution. Properly done, (moment contected at the deck to a properly engineered moment capable king post) a deck stepped mast is far superior to a keel stepped mast for offshore work. The problem is that there are few deckstepped masts that are properly constructed for offshore use.
I do think that the point is right on target about getting a lot of sailing over several seasons under your belt before selecting the ultimate boat to sail around the world.
