Cobalt Boat

Marker One ML4

300 HP engine

*Trailer included!*


This boat is an edition to the Platform Series at Cobalt Boats. Even though it runs atop three aluminum hulls the ML4 has a fiberglass deck. Which means its seat bases and all components have molded fiberglass parts. It could be categorized as a hybrid boat with the space and utility of a pontoon boat layout. It's the perfect boat with you in mind!

The L-shaped cockpit seating features adjustable backrests on both the chaise-style lounge and the portside passenger seat. The bow cockpit features wraparound seating with plush vinyl cushions. A center walk through leads to the nonslip bow platform. There's plentiful storage under the fiberglass seat bases both fore and aft.
