Metal Shark brought a 45'x15' Defiant-class patrol boat to this year’s International WorkBoat Show. The boats feature 30" drafts. The Jeanerette, La.-based boatbuilder is constructing up to 30 of the boats for Vietnam under the Foreign Military Sales program. Metal Shark can construct its Defiant class vessels with different equipment packages including fire pumps and monitors, davits, electronics and hydrographic survey equipment.
