Tired of those ugly black skid marks and scuffs on the side of your beautiful boat? They're usually caused by dirty dock wheels rubbing against your hull when the boat moves with the waves. These simple Dock Wheel Covers are the easy fix. They're like little sleeves (in a navy color, 9 inches in size) that you slide right over the existing rubber or plastic wheels on your boat dock or slip. They create a clean, protective barrier between the grimy wheel and your boat's gel coat. They're super easy to put on and help keep your boat looking pristine, saving you time and effort on cleaning and buffing out those stains. A super simple, affordable accessory that makes a big difference in maintaining your boat's appearance.
