2016 Cobalt Marker One ML4
The Cobalt Marker One ML4 is a rare and distinctive boat that blends the luxury and performance of a Cobalt with the spacious comfort of a tritoon platform. At nearly 25 feet in length with seating for up to 12, it’s designed for unforgettable days on the water—whether cruising, entertaining, or watersports.
This one-owner boat has been professionally serviced since day one here at our dealership, giving you peace of mind that it’s been meticulously cared for. It’s powered by a reliable Yamaha F250XCA DEC outboard, delivering smooth, quiet, and efficient performance. A matching trailer is included, making transport and storage easy.
What sets the Marker One apart is its custom, custom tritoon design with reinforced nose cones, one of a kind variable pitch lifting strakes, and a power wedge deck. No plywood in this boat! The deck is a well built fiberglass and gelcoat platform. This gives you the stability of a pontoon with the handling and performance edge that Cobalt is known for. Inside, the wide beam delivers a roomy, open cockpit with premium seating and upscale finishes that elevate the experience well beyond a typical pontoon.
