unlike every other poor bugger that owns a boat with a motor bigger than 6HP
this is another case where bureaucracy has one set of rules for those that can be ripped into at will and another set for those making money. It seems that if you have a vessel permanently(and probably a lifetime of use) you are incapable of using it without supervision and if you are "just visiting(and spending money)" never having had anything on the water bigger than that plastic tug boat in the bath when you were six you are fully capable!!!

as a side note in SA if it has a motor you need a liscence and rego... even if I put an electric motor on my inflatable kayak!!!
