2017 Marker One ML4 The ML4 innovative hull design features large tube diameters, lifting strakes, and chines to produce a noticeably different ride as comfortable in coastal chop as on a mirrored lake, with a quickness to respond and controlled stability in turns. Hulls of premium high gauge aluminum are bolted through a structural stringer system to an upper fiberglass deck for superior rot-free construction. The Marker One patent-pending power wedge flotation means the deck maintains a level feel even with the weight of a maximum horsepower engine astern.
