Look at the shape of your boat's hull. Always measure your boat to be sure you are ordering the correct cover. Do not rely entirely on manufacturer's specifications!

When determining center line length, add for options such as bow pulpits, trolling motors, and swim platforms. Measure in a flat straight line from the tip of the bow to the farthest point aft that you intend to cover (especially if you want to cover swim platforms). This measurement should be taken through the center of the boat. Do not measure upward and cover windshields, seats, etc.

When measuring maximum beam widths, also use a straight flat measurement from side to side. Be careful - on some boats the windshield area is the widest, on other boats, the transom may be the widest part of the boat.
