Once the preliminary operations are completed, leave the dock by means
of a boathook. Then start the engine at idle to reach the exit of the harbour.
After exiting the harbour at a safe distance, you can accelerate to the
cruising speed. Avoid sudden accelerations and high cruising speeds. This
would only increase the risk and the fuel consumptions.
A sudden acceleration reduces the planing time. Therefore, this manoeuvre
requires the utmost attention. In such conditions, a special ability and
quickness of movements are necessary to control the boat. We
recommend to accelerate gradually, regardless of the loading conditions.
This would prevent the "TAKE OFF" risk.
DANGER
It is extremely dangerous to plane over high waves. In this case the risk of
tilting is very high.
