I am not sure if their 27' is an Exc. but the larger 33-40 are Dennis's own mold. I had a 27' Avanti back in 1986 with a 575Merc w/#3, boat ran over 80 and handled well, considering the narrow beam (7'). This package was expensive, considering the price of a big merc & #3 for the 80's. They are built locally in Palmyra, NJ call Dennis Friedman the owner.
