I run a 25ft Bertram 1967 FBSF with a SINGLE 225hp Optimax swinging a labbed 15pitch Mirage plus. I fish with no less then 4 people and mostly full gear.
Ultra light with 1 person and 10 gallons of fuel, I just hit 40 mph on GPS.
With canvas up, 4 people, full fuel (80gallons), and gear, it will cruise at 24mph and top out at 36 mph.
This boat has a 10ft beam, and is over 25ft long with a flybridge. Planes off easily and stay on plane at 20mph.
Its all in the prop.
Just my 2 cents.
