We still have no real summer here but Amsterdam people don't bother and go out with a boat anyway. At a saturday night it is on the canals almost as crowded as in the streets.
This boat with only boys on board, students probably, we heard from a far distance coming with very loud music, the "boink, boink, boink" sound. Passing a boat with young girls was very exciting for them.
Others were more quiet with just a family on board.
As long it can float and has an engine you can go.
