Imagine, taking a 460mile trip over the big waters of Puget Sound, camping and visiting along the way, in a craft of only 16hp!Vanguard made just such a trip! Vanguard is a get out and go somewhere sev, and a screaming, gas guzzling frantic two stroke engine is simply not needed to get real performance! Suddenly waters that one would never think of as boating waters open up and the reward is new adventure!
With a hull size of 7 feet by 12 1/2 or 14 feet, Vanguard is the baseline sev for the new Sevtec series of sevs, and uses the Briggs and Stratton 16 to 25hp Vanguard V twin engines.
With a top speed of 35mph and fuel use of less than 3/4 gallons per hour, this sev can haul over 550lb payloads over big and small waters and has exceptional athletic abilities over rough terrain.
Plans and instruction manual are available. Critical parts for Vanguard such as propellers, fans, skirt material, drive hardware and foam for the composite hull construction are available from Sevtec.
Total cost of construction, including engine and critical parts kits for Vanguard is $2200 to $2900, and some 120 to 400 man hours.
Bryan Phillips, of Anacortes WA, and Dave Crawford, of Lake Forest Park, near Seattle, cruise their Vanguards near La Conner WA.
