Yards and feet. There are no boats that are a mile long!
8500 ft / 5280 ft/mi = 1.61 mi
6200 is a pure number - it is not a length of any sort. It is, therefore, totally inappropriate to try to compare it to a length.
100 mi = 528,000 ft
1.62 mi = 8,553.6 ft
1.2 mi = 6,336 ft
9 mi = 47,520 ft
It is 11.6 km (7.2 mi) in length and is on average 45 metres (148 ft) wide.
