Custom Marine Water Tanks

Made with FDA-approved, virgin polyethylene plastic resin, our marine water tanks are perfect for storing potable water in boats and marine vessels such as sailboats, yachts, or deep sea fishing boats. Designed with a one-piece marine tank, your water-holding tank is both durable and practical. Because our plastic marine tanks are seamless, they don’t crack or weaken over time.  Tanks have female NPT openings in the same position on one end, making them ideal for any marine plumbing.  Cost effective and eco-friendly, boat water tanks come with spin weld fittings to make sure your tank has the perfect fit. One Clarion is committed providing you with the highest quality marine tanks on the market!

Our Marine Water Tank Process

We are dedicated to providing a collaborative and efficient process for your custom marine water tank project. Our tanks don’t come with pre-drilled holes, so we have a blank canvas to place holes and fittings exactly where you need them. Your custom boat water tank can pivot to fit your available space.

  1. Start by simply filling in a tank drawing with your tank dimensions and specifications. Show on your drawing where you need the ports on your tank.  Be as precise as you can with measurements showing location.
  2. Once our team reviews your drawing, they will contact you with feedback and suggestions. 
  3. Our team works with you until you're satisfied with the design, and then processes your order.
  4. We encourage you to provide the most specific information available to fit sizes and locations for your tank. If you're not sure about all the details, our team is ready to guide you through the process, making any changes you need.

*Mounting straps are not included with this tank, and it is not for use with gasoline fuel storage. If you need a different type of tank, our team can help you find the right custom tank to fit your specific needs.

See our Marine Water Tanks (pdf) for more details.


Roto Molding for Marine Water Tanks

Your marine water tank starts with the process of roto molding, where heated virgin polyethylene resin is melted inside a hollow, closed mold. The mold, placed in the cast, is heated to 260°C – 370°C. As the mold rotates, it is evenly coated with the polyethylene resin, resulting in smooth walls with consistent thickness. This durable marine water tank makes a strong, seamless, longer-lasting water tank.

Marine Water Tank Accessories

One Clarion is proud to be an industry leader by making sure we meet your needs. We offer customizable tank dimensions to fit your specifications, and install spin weld fittings upon request. If your project requires a unique size or shape, we can even create a custom tool to accommodate your needs.

Our polyethylene fittings for our holding tanks and fresh water tanks are made through spin welding. This simple process produces a strong, durable permanent joint link and a great finish. We can make fittings for your tanks, ensuring a correct fit and are watertight. white fitting
