Re: Centreboard vs keel
To begin with, I would suggest that this is a very poor choice to build if your goals are lake sailing. Lake sailing tends to be a mix of extremely light air, and comparatively heavy air with relatively few medium days in between. This design would do poorly at either end of the wind range being obscenely heavy for a boat with this short a waterline length and being really short on sail area for lake sailing.
Normally, for all of the reasons mentioned above, I would agree 100% that the centerboard boat should be a more practical design for trailering. I typically am a fan of well designed keel centerboard boats.
But in this case, given your goals for the boat, I am not so sure that the centerboard version does make sense. Both versions of this design are severely short on sail area as compared to its drag, initial stability, and displacement. In the case of the centerboard version, there is less stability and so the sail area has been reduced as well. That would be okay if you normally sail in an area where the winds are rarely any more or less than 10 to 15 knots. But you are talking about both lake and ocean sailing and that requires a boat that is good at both ends of the wind range, which neither version would be, but the centerboard version with its smaller sail plan and stability would be much worse to the point of saying either change your sailing objectives or change your choice of design.
I would respectfully disagree with the statement "I would be wary if the design was for a fixed-keel yacht and the manufacturer offered a centerboard version as an option." since has been routinely done on boats with longer keels, and produced successful equally successful designs.
