When you Sell it. So the joke goes but I sold one about 20 years ago and prices have doubled many times. We had the top of the line for 45k. Inflation of boats has been amazing maybe I should have invested in boats.
Actually not sorry once you add maintenance, storage, gas, fees, equipment etc boats are just a money suck and they rarely get used.
Much betttet to Pay way too much for a bike that you can use 150 times a year
