Unusual water-craft uses FR composites
Looking like a cross between a Jet Ski and the Space Shuttle, the Hydroforce by Anchor Industries Inc. is touted by the company as a ``strikingly different alternative to conventional boating.''
Anchor, a custom supplier of fiberglass-reinforced structural composites based in Traverse City, Mich., introduced the boat in the spring. Orders for the $12,000 two-seater craft have arrived from the Mideast, Latin America and Japan, said spokesman Rodney Caswell.
Anchor promises a top speed of 40 mph for the Hydroforce, which has a fiberglass hull and comes with a removable canopy. A joystick control allows either passenger to drive. Anchor said the boat can turn 180 degrees within the width of its wake.
