Two things have driven recent powerboat design.
First, the fixed length of marina berths encourages boats to be built bigger through depth, beam and height, rather than length, leading to high-resistance hull shapes.
Second, lighter and more powerful engines means these higher resistance hull shapes can be made to perform well with more horsepower.
These factors have shaped the design of the V-bottomed flybridge planing launch, which due to its increased beam, height, windage and weight, often requires high horsepower engines.
Consider this. Take a given quantity of boatbuilding material, labour and engineering, for the same price one could build either a 10m V-bottomed, flybridge, planing launch, or a 12m, low-profile, non-flybridge, semi-displacement launch.
While both launches will have similar volume and accommodation, compared to the 10m planing launch, the…
