Comments from the Marblehead Reporter:

"The Marblehead-Swampscott YMCA Children's Island Day Camp has a new workboat, "Island III," designed by naval architect Dieter Empacher. The new workboat has a nine-foot beam, carries a cargo of 3300 pounds and has a Honda four-stroke outboard motor. 'The Island Workboat has a unique design concept that makes it a true workhorse,' Empacher says. The boat is built of aluminum to achieve the strongest construction possible. The workboat design is a flat bottom pontoon with a tri-hull underbody. Since each pontoon is airtight, the boat is virtually unsinkable."

DESIGNER'S COMMENTS

The "Island Workboat" has a unique design concept that makes it a true work horse.

The boat is built of aluminum to achieve the strongest construction possible. Aluminum has greater strength pound for pound than steel or fiberglass. The workboat design is a flat bottom pontoon with a tri-hull underbody, and because each pontoon is air tight, the boat is virtually unsinkable. The boat has a double bottom that leaves the smooth loading floor unobstructed for working and storage. The bow door is hinged to open for easy loading and unloading. To provide a stable landing platform while beaching, the side pontoons have more draft than the center pontoon and prevent the boat from rocking.

Designed to have the loading deck above the waterline at all times, the tri-hull provides for the greatest possible form stability. The three pontoons also create less resistance while pushing the boat through the water than a mono-hull of the same dimensions and, therefore, less horsepower is needed to maneuver the "Island Workboat".
