Conditions Affecting Operation
Weight Distribution (Passengers And Gear)
Inside The Boat
Shifting weight to rear (stern):
• Generally increases speed and engine rpm.
• At extremes, can cause boat to porpoise.
• Causes bow to bounce in choppy water.
• Increases danger of following wave splashing into boat when
coming off plane.
Shifting weight to front (bow):
• Improves ease of planing.
• Improves rough water ride.
• At extremes, can cause boat to veer back and forth (bow steer).

Bottom Of Boat
To maintain maximum speed, the boat bottom should be:
• Clean, free of barnacles and marine growth.
• Free of distortion; nearly flat where it contacts the water.
• Straight and smooth, fore and aft.
Marine vegetation may accumulate when boat is docked. This
growth must be removed before operation; it may clog water inlets
and cause engine to overheat.
