When I did my boat. I simply attacked it with a dremmel. But I have seen one who placed it in sand and then spraypainted the sides, so he had an effective waterline to cut after. If I do another one I think that is the way I would do it.That is what I done, not very tidy but it will be hidden by the water. I didn't have enough sand or a useful sized container to try the spray painting idea
