The problem with the scheme is it is like an MOT, condition at a moment in time.
We must have all seen the pre-inspection preparation, I certainly have. Tailgate open seats down to accommodate the second outboard tank, the spare gas bottle that does not fit in the locker, the portable gas heater, the generator with its built in petrol tank and the tender's outboard stowed under the cockpit sole with it's tank not forgetting the gas bbq.
And yes why is a boat safe for it's first 28 days on the water? Don't get that one especially if it has been bounced about on a trailer for a couple of hundred miles.
I am not saying it is a bad thing but it needs renaming along the lines of mechanical, gas and electrical install test. Otherwise it indicates a boat is safe and seaworthy which is just not the case.
