Lay up or longer stops
If the engine lies idle for more than two months it must be prepared. To run it in the harbour now and
then is no advantage if it isn’t possible to put a load on the engine so it will be thoroughly heated.
The 230 V shore connection should be left disconnected for longer stays. At least the flexible
cable to the water heater should be unplugged. (Located in the engine room)
There is almost always a small potential difference between the earth lead and the true earth in the water
inside. This can cause damage in the long run.
Some insurance companies claim that all skin fitting valves should be closed.
DO NOT CLOSE THE COCKPIT DRAINS. In the event of rain it will
only be a question of time before the water level in the cockpit is so high
that the water will enter into the boat.
The water tank:
The water will maintain quite fresh for a long time if the tank is completely full. It should then be
pumped out and refilled with fresh water when you return to the boat. Based on many years of
experience we can say that special chemicals are not needed when the water is of good quality. Always
taste and smell the offered water before filling. Be sceptical of water with a mossy smell. It may cause
growth inside the tank.
Sometime the question of cleaning of the tank arises. There is no reason to rush, don’t open the
inspection hatches if you don't have a problem. But if you do open them, don’t be alarmed if the inside
looks far from clean. The same applies probably to the water pipes in your home as well.
