Mike, If looking for a monohull in the BVI, what you are describing is as rare as hen's teeth because it requires very high freeboard in the aft part of the boat and pretty much all of today's manufacturers have opted for "sleek" lines with low freeboard aft ... negating that possibility.

The old center cockpit boats all had huge aft cabins, but what you gained in on board space, you generally lost in sailing efficiency.

Many yachts such as the Beneteau 41 have stand up headroom in the aft cabin, but you are not going to find many yachts offering stand up headroom "throughout" the aft cabin, unless you can find a much bigger yacht and probably an older yacht.

The Beneteau 55, 3 cabin has a good amount of stand up headroom in the aft cabins. The same holds for the Jeanneau 469 and Jeanneau 509, 3 cabin yachts.
