3.6.1 Measures before docking for winter
If below-zero temperatures are expected, drain cooling water from the engine following the
engine manual instructions.
Dock your YAMARIN 4730 in good time before the water freezes. The boat is not designed for
use in ice.
Before docking, it is recommended to do the following:
-
Preliminary wash of the hull.
-
Removal of excessive gear from the boat. However, leave safety equipment , for
example the fire extinguisher in the boat.
3.6.2 Washing and cleaning
Keep the boat clean and tidy. It will add to your comfort and safety, as well as the resale value
of the boat.
Normally it is sufficient just to wash and wax the deck and sides. A special boat cleaning
detergent is best for washing. Do not use strong solvents as they may damage the gloss of
the reinforced plastic surfaces. Mildly abrasive polishes can be used to remove chafings and
embedded dirt.
We do not recommend waxes that contain silicon because they decrease the adhesion of
resin and paint and therefore make the repair of possible damages more difficult.
After hoisting the boat from water, wash the bottom immediately. Algae and slime will come off
easier if they are not let to dry.
3.6.3 Winter storage and service
Perform winter service to the engine and other accessories following separate manuals. If
your boat is stored outside or in a humid place during the winter, remove textiles and other
equipment that may corrode or become mouldy in moist conditions. Wash ropes in fresh
water. Worn ropes should be replaced. Leave seacock open and also release the drain plug
from the transom plate.
The electrical instruments are also best protected against both oxidation and thieves by
removing them and taking them indoors for the winter. Remove batteries and store them in a
dry and warm place. Charge them at least twice during the winter. Spray the wiring connectors
with suitable corrosion and moisture preventing agent.
Check the condition of the hull and rub down any dentings to make sure that all possible
moisture inside the laminate dries up. Have the damages repaired (or repair them yourself) in
spring before launching the boat.
Cover the boat in such a way that snow cannot gather in the boat or the cockpit. Always make
sure, however, that there is enough ventilation. Snow will not accumulate on the canvas if the
ridge angle is steep enough (at least 90 degrees). A suitable canvas size is then 6 x 4 m.
