Specifications include, but are not limited to: The Division of Environmental Assessment, Marine Unit, is looking to procure a new fiberglass boat for their Marine Environmental Monitoring Program and Marine Vegetation Mapping Program field work in Maine’s estuaries and marine waters. The boat (specifications below) will be required to operate in very shallow water and water >100 ft deep, occasionally be grounded on clam flats, and be operated in larger, rougher bodies of water along exposed coastline. To afford maximum stability when working over the bow, the vessel must have full bow sections providing added buoyancy forward, little reduction in freeboard, and a broad working platform forward. The bow of the boat must be rounded (not pointed) and have no obstructions such as cleats or chocks that might catch nets or sampling equipment. The hull must be highly flared forward for a dry ride and added buoyancy when encountering steep seas. The hull’s bottom is to be of moderate deadrise, 10 degrees (+/- 2 degrees) at the transom tapering to 35 degrees (+/- 2 degrees) in the bow sections. Hull sides aft must be near vertical to facilitate working sampling gear over the side. The transom must have some curvature to allow following seas to flow around the transom, allow astern backing without excessive flooding over the transom, and to provide the inherent strength of a curved structure versus flat. Transom height at its lowest point must be 25". The hull must have flotation that meets or exceeds the level and upright standards established by the Coast Guard. The boat selected for these needs is a 2023 Maritime Defiant 210 or equivalent.
