Lots of interior space allows the addition of some interior appointments for cruising comfort, and a large hull makes for a better ride in larger waters. This is the sev that cruised from Anacortes, WA to Juneau, AK, over 1400 miles.
With a hull size of 8 feet by 18 1/2 or 20 feet, Explorer is a scaleup of the Vanguard design, and uses a Subaru or other 4 cylinder engine. Two aluminum frames automatically extend when the engine is started so this sev flies as if it were ten feet wide. (Note! The drawing shows the sev at flight configuration, 10 feet wide to the edges of the aluminum frames. It does automatically fold for highway trailering under 8 ft width.) With a top over water speed of 39mph and fuel use of around 2.5 gallons per hour, this sev can cruise relaxed at 30mph plus speeds on just 65% power. This sev can haul over 1600lb payloads over big and small waters.
