Boat Bottom
For maximum speed, a boat bottom should be as flat
as possible in a fore-aft direction (longitudinally) for
approximately the last 5 ft. (1.5 m).
The bottom is referred to as having a “hook” if it is
concave in the fore-and-aft direction. A hook causes
more lift on the bottom near the transom and forces
the bow to drop. This increases wetted surface and
reducesboatspeed.Ahook,however,aidsinplaning
and reduces any porpoising (rhythmical bouncing)
tendency. A slight hook is often built in by the man-
ufacturer. A hook also can be caused by incorrect
trailering or storing the boat with support directly un-
der the transom.
