What size will my slip be?

What size slip will I have with the new floating docks?

Slips were widened by 1.5 feet, so nominal 16 ft. slips became 17.5 ft. slips. The existing slips are measured center to center of the mooring piles, which are a nominal 1 ft diameter. Thus, the slips as they exist are clear 1 ft less then the original stated dimension (1/2 of 2 piling widths). Therefore, it took 1.5 feet to compensate for 2 feet of finger pier and 6 inches of mooring piling, which are not normally used on floating docks, since you tie up to the dock.
