About a million years ago, I was picking a boat up in Liquordale for a delivery to Newport. (For a number of reasons, staying vaguely sane being one, it was the last delivery I ever did.) It was a sailboat with twin engines and the engine control levers conveyed their commands to the engines via electrical wires. Naturally, on the eve of departure, one of them quit. If it had been a mechanical fix, I could have taken care of it but since my electrical knowledge ends at Ohms Law we had to call in the expert and delay another day. Of course, I was convinced the damn thing would fail again as soon as we cast off.
Give me nuts and bolts and rods and pulleys and stuff I can understand.
What if the guy on the next boat has the same wireless gizmo and wants to leave down the same time you do? Yikes!
