It's an 87' Northcoast. I recently saw this boat in Lauderdale too. She's a beauty. Northcoast has built some truly outstanding larger yachts. A few of them have been discussed on YachtForums. Paladin is one of them (the mother ship to Paladin's Shadow).
Can't tell you much about pricing, maybe a YachtWorld search will reveal some numbers. The boats are built by Steven Yadvish in Tacoma, Washington. I've contacted them several times for info, specs and images, but never received anything. I get the impression he's a pretty hands-on builder... and thus pretty busy!
(If you get a hold of him, tell him he's MIA on YF!
