Boats
Having moved to an island two years ago, I have occasionally entertained the idea of buying a boat.
But AFAICT, they're expensive to buy and expensive to own. They are also fairly slow moving, so I might need longer vacations to get to where I want to go. Which also will set me back a fair bob. OTOH I can probably jury rig the autopilotsoftware from a Tesla to pilot the water vessel while I'm sleeping.
Any advice? Apart from skimming my e-mail for plausible "get rich quick!" schemes?
