1. Measure your boat's centerline length (straight measurement from bow to stern) NOTE: Do not measure up and over the windshield.
2. Measure your boat's beam (the flat width of the boat at the widest point near mid-ship.
3. Find the boat description from the selection guide (boat length, centerline length and beam width) that best resembles your boat. Using the size chart for your boat style, check measurements which equal or exceed your centerline and beam dimensions. This is the correct cover for your boat.
