|How many miles does it take?|
- There are no jackrabbit starts.
- There are no sliding stops.
- There are no high-speed corners, no limited slip differential to cause extra wear.
How many years did it take to create this wear? I suspect that this cart (and many others like it, also still in service) were new when Shilshole was a new marina, in 1962.
So let's assume that a cart makes 2 round trips down the dock every day. G Dock is a little over 1000 feet long, but we'll make the calculation simpler by assuming that it is 1320 feet, a quarter mile. Then those two round trips total one mile. A mile per day, times 365 days per year, times 50 years equals 18,250 miles.
