It is awesome for a 16 foot boat with a factory stock 150 HP to go 70 MPH quietly, without strain, without constant correction of the steering wheel, and with stable handling.
My scaled down version is a Glastron/Carlson 1987 CVX-16 with a straight hull with no nicks or scratches, without a hook at the end, running a stock 1985 115 HP Johnson weighting 302 pounds, achieving 55 MPH at about 5,400 RPM, with effortless steering and predictable handling.
