Hey Sinkorswim, I got your PM and I hope you choose the BT. They are a great boat. The BT is a much higher quality boat, and each one is built to the customers specs. It also runs a true 75mph with a pair of 525's.
Black Thunder hand lays their components using only the finest materials available in the market today. Baltek AL600 is used to core the entire boat and both bi and tri directional glass to give you peace of mind in any seas you may encounter. Unitized construction is further enhanced by through bolting the hull and deck every 6 inches, and the joints are then layered for four layers of glass. BT has never had a hull fail.
Contrary to some beliefs, the new 460 hull runs great. It sits level, takes a nice attitude, and eats up the rough stuff. They just finished a 460 with a pair of 850's and it ran 95 on the limiters, and it runs and handles quite nice. They hope to get 100mph when they are done tweaking props. I wonder what it would do with some 1200mercs?
Best of luck to you in choosing a boat!
