I believe it's a 1958 FireFlite, the only one of those three years with the swept fin cap, the Red Fish and the Barracuda never had the swept fin cap, and the Red Fish fin'e were strait in top, just slanted upwards to the back, Glastron and Barracuda, and Lone Star were raised and curved.
The red boat posted above comparing the decks is a 1957, a bit different than the 58's
