It just something that boaters say to each other as a bit of humour , but there is a bit of truth for some as they discover , one way or another , that they are not boat people , sell the boat to pay for the therapy they're going to need to rebuild family bonds after that experience

.
I guess for those that the expense of a boat puts them close to the bread line even a yearly service is a big deal , let alone something being wrong . A lot of Kiwi boaters use their boats for recreation , as a life experience thing for the Kids as they grow and we put enough value on that that some families will commit a significant amount of available income to invest in that .
If one is capable of maintaining the boat / trailer and accessories oneself then your well in , but if you are faced with paying an expert to do all that it can seem like that bloody great hole in the water at times .
