The only difference between the system Peter describes for the GB32 and the system on our boat is the pump used. The Whale Gulper is an excellent choice for this service. Our boat was fitted with a pump called-- I think-- a peristatic pump, which is like a blood transfusion pump in having rollers that run round the inside of a circular chamber and compress a rubber tube that has the material being pumped inside it. I suspect the thing will pump wet sand, but when it craps out we'll replace it with a Whale.
