Massachusetts' Nantucket Island has seen customer attitudes to pumpouts improve over the years. In the early years there was little demand, and I had to strongly urge it to be done. Now demand is high and they now expect it. If one boat is being pumped, the surrounding boats request a pumpout right then. On Lake Erie in Ohio, Battery Park has their CVA funded pumpouts located on their fuel dock.
Boaters are so happy with our staffed service that they tip very well.
Using that as an incentive to summer staff, I offer the pumpout station job mainly to the returning dock hand with the best work record from the previous year.
