A Seafari is about 200 lbs heavier than a CC model, and most of the extra mass is in the cap, windshield, cabin door and bulkheads, but the basic hull weighs about 1600 lbs! My gut feel is that raising ~150 lbs a couple inches is basically a nit compared to the mass of the basic hull and bulkheads which aren't moving. I suspect that the effect on vertical CG is smaller than what you get when you mount a T-top with a fiberglass cover and an electronics box up about 7 feet off the deck of a CC model!

Also keep in mind that hull shape has a big effect on initial stability . . . the 20 has a relatively low (~18 degree) deadrise hull, so it's fairly stable at rest. I remember rafting up with Connor a few years ago on an overnight adventure up to Mosquito Lagoon, and I was surprised that his 25 was noticeably more tipsy than my 20 when I climbed aboard for dinner, despite it's 6" wider beam and heavy I/O engine and big fuel tanks deep in the bilge! It's vertical CG is probably lower than it is on my outboard model, but the difference is the extreme 24.5 degree deadrise on that hull, which is even higher than on Moesly's narrow 6.5' beam 25-30' race boats!
