inner shell and sides of an ABS boat. The removal
of abrasions and difficult stains can be done us-
ing a fine polish. If the boat has been kept in the
water, wash the hull as soon as it has been lifted
out. Algae and slime are more easily removed if
they are not allowed to dry. You can use a brush
or wooden or plastic scraper to ease the work, but
avoid the use of a scratching metal scraper.
NOTE! Do not clean with acetone, thinner, petrol,
ketone or other strong solvents, as they may dam-
age the plastic surface.

4.2 Winter storage

The best place to store a Terhi boat in winter is in a
shed or under a roof. The best storage position for
a rowing boat is upside-down, resting on trestles
(figure 8).
For planing and console boats stored on trestles
or a trailer, ensure that the boat's weight is evenly
distributed on its supports. Support surfaces must
be wide – for example a board lying flat is well-
suited to the purpose. When storing the boat on
a trailer, the fastening straps must be loosened.
If the engine is still mounted, its weight must be
supported. During the period of storage, heavy
loose items such as the battery and fuel tank
should be removed.
The Terhi 475 is also equipped with a bilge-
water drain plug, located under the plastic cover
beneath the tank. Bilge water can be drained
out here when the boat is dry-docked. Leave the
plug open during storage, so that any condensa-
tion water can drain away. Always keep this plug
closed when the boat is in the water.
If stored outdoors, cover the boat with a non-
transparent tarpaulin. Ensure, however, that the
boat has sufficient ventilation. When storing out-
doors, make sure that an excessive amount of
snow cannot accumulate on top of it. Storing a
Terhi boat on its side is not recommended.

NOTE! The tarpaulin and its fastening ropes will
chafe the surface of the boat if they flap and move
in the wind, so fasten them with care.

4.3 Engine and other equipment

Study the engine manual for instructions on win-
ter storage and servicing and the spring overhaul.
Have them done by a qualified service engineer
or, if you do it yourself, take the utmost care over
the task. Other equipment requiring regular serv-
icing includes:
- steering and engine control equipment
- navigation lights
- covers
- battery
Remove the batteries during winter storage,
store them in a cool dry place and charge them
at least twice during the winter. Spray electri-
cal connections with suitable anti-moisture and
anti-corrosion substances. Carry out servicing on
other equipment according to their manuals and
instructions.

4.4 Anti-fouling

In sea water, you can prevent vegetation and bar-
nacles from getting attached to the hull by ap-
plying anti-fouling paint. All light-coloured, hard
types of paint are suitable for Terhi boats. Careful-
ly observe the instructions provided by the manu-
facturer. You can find water-line measurements for
anti-fouling paint at TerhiTec Oy's website (www.
terhi.fi).

4.5 Care and maintenance

Repair, or have repaired, any possible scratches
or dents, according to section 4.6. Small surface
scratches can be ignored as they do not adversely
affect the integrity of the boat. Washing and wax-
ing, as described in section 4.1 will help to keep
the boat clean and neat throughout the boating
season.
