about boat tanks

Marine tanks are onboard storage tanks for boats, sailboats, yachts, trawlers, and vessels. There are two types of boat tanks: fresh water tanks for storing potable water and holding tanks for collecting and storing of grey water or black water. National Tank Outlet’s marine tanks are manufactured from high-quality polyethylene resin that is BPA free, FDA-approved for potable water, and ANSI NSF 61 compliant.

Plastic marine tanks are made by manufacturers Ronco and Dura-Cast. The tanks are rotationally-molded with polyethylene resin to offer superior durability, service life, and resistance against cracking, rusting, and corrosion.

Marine tanks are most-commonly rectangular in shape. Custom-molded options are available for specific boat makes and models. Poly marine tanks are available in numerous capacities, dimensions, and wall thicknesses to guarantee the tank works for the specific application. These tanks can be used as new or replacement marine tanks. Tanks are available with pre-installed fittings and lids or as a blank tank with custom DIY fitting packages.
