I just cannot see how someone who knows about boats could possibly pick up the info on solving Crossfire problems to be too effective out of the gate. It would take time and on any particular problem the customer would be footing the bill as the clock ticked.
Presumably he would have his wits and need access to this forum to gain insight into a problem. Getting back on a plane without solving a problem would not lead to a good record of customer satisfaction.

Even a leak in the trunk is not too obvious, as the car is not going to sink. That is a joke.
