Hull Designs And Uses
Boat designs encompass a vast range depending
on the specific use for which the boat is planned. Boats are basically
designed in two categories:
Displacement vessels are designed
to move through the water with a minimum of propulsion. They will have
a large underwater profile and will ride comfortably although slowly.
Trawlers and large sailing vessels are displacement vessels.

Planing vessels, however, are designed
to actually rise up and ride on top of the water when power is applied.
They require considerably more horsepower
to get the boat up but they can attain much higher speeds from the reduced
friction of moving on top of the water rather than through the water.
