Hanse 400 and Rainman

“One of the most frustrating things when cruising, is the need to go into marinas regularly to fill up with fresh water. The more people you have on board …well – 330 litres of water just doesn’t seem to last that long without rationing does it!

For the last few years I had looked at various options to install a watermaker on Mica, our Hanse 400e .The high cost, relatively low output and complexity of installation had always put me off.

However, a manufacturer has finally come up with a product that overcomes all these barriers.

The first time I saw the Rainman Desalinator was at the Sydney Boat Show last year – straight away l knew l had found my solution!

At that stage, the product consisted of a self- contained pressure supply unit fitted with a small petrol driven Honda
motor. A choice of reverse osmosis tubes give different fresh water outputs.

Not long after, Rainman launched an electric pressure supply unit that runs on 240 volts and can be powered by a 2KW inverter or a Honda 2 KW generator.

I already had a Honda generator on my Hanse “Mica” so this was the option I selected.

The reverse osmosis (RO) tube is what contains the membrane that separates the salt from the pure water.

The ‘economy’ RO tube is just over 1m long with quickfit connections for the high-pressure input supply line, the pure water output hose and the pressure control valve to which the waste water output line is connected.

I took some quick measurements and found that the pressure control unit would fit in my deep cockpit locker, along with the Honda Generator.” . . .
