2 Using the boat
2.1 Mooring and anchoring
Always moor your boat with care even in sheltered an-
chorages, as weather conditions can change rapidly. The
cockpit of an unloaded Terhi boat is designed to drain
rainwater. So, when unloaded, the boat can be left to
float without its drain plug fitted, allowing rainwater to
flow out.
NOTE! Remember to replace the drain plug when you
step into the boat or load it. Ensure that the drain plug
hole is free from foreign objects such as leaves. Depend-
ing on the weight of the engine and any other equipment
in the boat, water may not necessery completely drain out
of the boat when the plug is open. If water has remained
in the boat for a long period, it is advisable to clean the
surfaces immediately after draining (see section 4.1).
NOTE! Where necessary, use suciently large fenders
to prevent scratching the sides of the boat. The mooring
lines should be fitted with dampers/springs to suppress
jerks.
2.2 On-shore storage
If the boat is stored on a stony beach, we recommend
the use of a roller slipway or hose slipway, as shown
in figure 1.
Figure 1
If the shore is soft sandy or muddy soil, you can simply
pull your boat directly onto the land. Remember to lock
the engine in the ‘up’ position before bringing the boat
ashore.
WARNING! Do not try to stop the boat by hand. Do
not put your hands or feet between the boat and the
quay, the shore or another boat. First practice berthing
in good weather conditions. Use prudent but purpose-
ful engine throttle.
NOTE! The water run-o channels around the boat’s
hatches do not function as designed if the boat is
stored at a steep angle, either lengthways or sideways,
for example, when pulled to the shore. If the angle is
too steep, water can collect in the boat’s storage spac-
es or electrical equipment.
2.3 Installation of steering console and rails
Installation instructions for the steering console and
rails are included in each package. By observing these
instructions, you will achieve the best results. The
steering wheel and system must be CE-certified. This
can only be guaranteed if original Terhi parts are used.
Always consult your dealer if you are inexperienced in
installing items.
2.4 Fire extinguisher
Boats with a maximum allowable engine power of
26 kW (35 hp) or more must be equipped with a fire
extinguisher. For Terhi boats, this applies to the Terhi
475 models. Fire extinguishers fitted on boats must
be serviced annually. Read the user and maintenance
instructions that are supplied with the device. The fire
extinguisher has been placed either inside the port
side steering console, or under the seat/bench in the
bow.
2.5 Driving
The trim angle of a boat has a significant eect on
driving characteristics and fuel consumption. The trim
angle can be adjusted by load re-distribution and ad-
justing engine trim angle.
A correct trim angle in conjunction with a suitable
speed makes driving enjoyable and safe, even in a
swell.
WARNING! High speed and sudden steering move-
ments, especially in high seas, may result in loss of
control of the boat and excessive heeling angles. Al-
ways consider your own driving skill, your speed and
direction, if you have to set o into conditions exceed-
ing the design specifications of your boat.
WARNING! Observe the recommendations on the
manufacturer’s plate concerning the maximum permit-
ted number of passengers and maximum load.
