More Information:

The new Marker One Platform Series M27 is a boat that defies traditional categorization. Is it a pontoon? It runs on three elongated aluminum hulls that resemble the tubes of a pontoon boat. But its deck is all fiberglass, putting it more in line with a deck boat yet with the wide-open seating of a pontoon. So where does it fit? Marker One, a division of Cobalt Boats, didn’t even try to make it fit. Instead it created its own category of boats — the Platform Series.

You can tell a boat is innovative when it has three patents pending. The first has to do with how Marker One joins the fiberglass decking to the aluminum hulls. The deck is a solid 2 inches thick, which makes for terrific structural integrity while dampening noise from underneath. The second patent pending deals with the aluminum hulls. All three have lifting pads as well as lifting strakes that curve upward toward the nose cone. The strakes help the boat generate lift and lean inboard while turning, reminiscent of how a V-hull would turn. The third patent pending is for the wedge-shaped stringer system. Its thickest point is at the transom and it tapers to the bow, which helps the boat sit level and creates a very stable platform for the passengers on board.

Passenger comfort abounds throughout the well-organized and high-quality furniture. The bow lounge features wraparound benches with forward-facing reclining seat backs abutting the consoles. Flip-down armrests complete the lounging comfort. The aft lounge features seats with adjustable seat backs so the crew can sit and lounge as they please. The 23 cup holders on board ensure that no one will go thirsty.


The helm features a double-wide captain’s chair and a great view of the water, key for a boat capable of brushing 44 mph. Those lifting pads and strakes help it reach plane in three seconds while jumping to 30 mph in 10 seconds.

The M27 is the flagship of the Marker One lineup, but there’s also an M25, which carries many of the same features and amenities but runs a foot-and-a-half shorter.
