Calculate your water supply, consumption per person and cruise planning

To calculate the supply for your cruise planning, reckon on twelve litres per person per day;

five is possible if you are careful with it,

and with a shower on board it becomes twenty.

Water consumption determines how long a leg between two harbours can be. Twelve litres per person per day covers drinking, cooking and washing without anyone having to go short, and with a shower on board that figure soon doubles. A watermaker changes the arithmetic, but it needs power.

From the insurance point of view, water tanks are above all a source of claims. A burst hose or a leaking joint puts the interior joinery, upholstery and electrics under water, and that is expensive. Whether such damage is covered depends on the cause: a hose that bursts suddenly counts as a sudden event, whereas a pipe that has gone porous over the years is wear and tear.

Under full hull cover, the cause is what counts: what is covered is damage that goes back to an insured event, such as an accident, a storm or a fire. Wear and tear is excluded, and a line that has gone porous over the years is wear and tear. So check hoses and clamps before every season.
