Mariner, 12 to 16 people, 14 ft x 28 ft hull
The Mariner has all the features of the Vanguard and is sized to take advantage of the power available from mid-sized automobile engines. It's 14 ft x 25 ft hull can handle bigger waters, and adverse conditions, and folds to under 8 1/2 ft trailerable width when the sev is shut down. A sev as large as the Mariner can be used in commercial operations such as a supply vehicle for a backwoods camp or as a tourist attraction. A windscreen, heater, enclosed hard cabin with standup headroom are reasonable, due to the huge payload (3000 lbs) of Mariner.
