"   Justin Martin N. Ferrisburgh, VT. Age: 31 Years on Job: 12     Justin Martin never planned to build boats for a living. After high school, he took a summer job working with his older brother constructing composite canoes. Twelve years later, Martin is a head builder at Adirondack Guideboat, which specializes in a rugged boat that&amp;#039;s light enough to be portaged but large enough to carry three men, two dogs and a hunting bounty. In addition to the company&amp;#039;s legendary custom-built wooden guideboats, Martin and his brothers churn out more than 200 Kevlar boats each year. Working with his family is what Martin loves most. &amp;quot;We can build an entire boat without saying a word,&amp;quot; he says. &amp;quot;We&amp;#039;ve always worked together. I can&amp;#039;t imagine it any other way.&amp;quot;  Building a Kevlar Guideboat 1. Make a Mold Each Kevlar composite boat starts with a 300-pound fiberlass mold cast from one of the company&amp;#039;s wooden models. Molds take one month to build, and make up to 400 boats. &amp;quot;It involves endless sanding and polishing,&amp;quot; Martin says. &amp;quot;Any flaw in the mold is in every boat that emerges from it. It has to be perfect.&amp;quot; 2. Apply Skin Coat Martin lays a dry sheet of fiberlass over the mold. Next, he pours in a pigmented polyester resin and rolls it along the entire form, using a paint roller and a small brush taped to a 2-foot stick to get the resin into the bow and stern. After the resin hardens overnight, Martin sands it with 60-grit paper. 3. Layer Kevlar Over the skin coat goes a solid sheet of Kevlar and a layer of overlapping 50-inch fiberlass squares. That&amp;#039;s followed by a second layer of Kevlar. Martin uses a corrugator to roll out the air between layers, then adds a final sheet of fiberlass. 4. Finish Build After adding the seat cleats and another layer of fiberlass over flotation tanks at each end, Martin applies a gel coat to keep the outside color uniform. &amp;quot;We have about 20 minutes to roll and paint the inside of the boat before it starts to cure on us,&amp;quot; he says. Finally, the mold is removed, and a deck and gunwales are added to give the boat structure. "^^<http://www.w3.org/2001/XMLSchema#string>
