“My experience with Seatask and the rainman watermakers has been excellent. Chrstopher Burton was extremely helpful and responsive in every step of the purchase/deliver/setup. He helped me figure out what I needed and shipped it quickly. The unit itself is great. Easy to setup, easy to use and exactly what we needed (a reliable, portable watermaker to extend our cruising range and reduce reliance on shoreside solutions in the Caribbean). Will likely buy another one next year for our fleet. I highly recommend this company and product..”

Having a 4kw generator made the electric high output unit the best choice for us. The portable aspect was the clincher, not having to install parts and pieces was the second most important issue. Taking the water maker off the boat for the several months when we don’t cruise, and storing it in a closet at home, is huge. It was extremely easy to lift the unit out of the lazarette, set it on the deck and drop the hoses overboard.

We spent 3 months in the Exumas Bahamas this past winer and unlike last year when we had to continually go to the dock to take on water we were able to produce our own water using the Rainman RO system. It worked beyond our expectations and produced water at about 30 gallons per hour. We hold 500 gallons and never ran out of water even with multiple guests on board. This product has saved us thousands by not having to install a permanent system on our boat and it is portable so other boats that travel with us are also able to produce water due to how portable it is. We are very happy with our choice to get the Rainman RO system.

Chris and his team did a great job helping us with getting our unit through French Customs in La Rochelle. We used our Rainman watermaker on a daily basis as we spent forty days total (thirty at sea) crossing the Atlantic from La Rochelle to Tortola BVI. We had six on board and so each day we’d top up our tank averaging 150 litres a day which took the rainman about 11/4 hours to make from beginning to end. The system is simplicity itself and after the first couple of times became just a routine of life on board. Our skipper who has fought and lost with many types of watermaker was most impressed.
