Risk of freezing
The risk of damage from freezing is less in the water than on land. In the water the boat will survive
short spells with minus 5° C without problems. This is however not valid if you have a thermostat
mixer for the shower armature. It will freeze and burst at only a few degrees below 0°.
If your boat is stored on land everything is different. If there is the slightest risk of frost, all measures
must be taken to prevent damage from freezing. The secondary cooling water system of the engines
(also the generator) should be checked regarding anti freezer.
The skinfittings
See the following pages.
Every skinfitting under the waterline has a ball valve on the inside. These require no greasing or
maintenance. All valves should be operated now and then. In freezing conditions they should be left
open.
Hose clamps should NOT be tightened more than necessary, and under no
circumstances with your full strength.
