A Seadog will meet your requirements. Also many Colvic type motor sailors were fitted with bilge plates.
The reason they are few and far between is that sailing performance gets compromised - although the Seadog in particular has a fine reputation for both seakeeping and adequate sailing ability. Another boat you may consider is a MG designed boat such as a a Lone Gull or particularly a Tidewater, but these are wood and a bit old fashioned. One or two for sale recently have been really good quality.
If ability to dry out is an issue you are probably better of with a long keel and legs.
I have an MG Eventide which was originally long keel and bilge plates and was transformed when I took the plates off and deepened the keel.
