For boats, floats, hulls and other marine parts and products, rely on our engineers to steer your project

MODRoto floats your boat.

Rotomolding in one piece MODRoto custom designs and manufactures marine fuel tanks, watercraft hulls, marina dock floats and other parts and products using rotationally molded plastics to withstand harsh, salt water, marine environments. Our custom plastics design engineers often earn awards from the Association of Rotational Molders that recognize excellence in rotational design and rotomolding for marine products including a Hobie Cat hull, a fishing boat and a kayak, among other watercraft.

Often rotomolded into a single, uniform piece from 100% waterproof polyethylene, these plastic fuel tanks, hulls and other parts and products resist attack from salt, gasoline, diesel fuel and other corrosives. Marine products may be rotomolded in virtually any shape with long necks, contours and configurations that simply are not possible to achieve with other plastics processes – while maintaining a consistent wall thickness. Plus, MODRoto engineers offer unmatched skill and experience in rotomolding with double-walled, foam-filled products to manage weight and buoyancy.

No welds, no leaks, no problem

These custom plastic fuel tanks, parts and products may be rotationally molded in a single piece with molded-in inserts for tight tube connections. There are no welded seams or corners that weaken, fail and leak into the ocean environment.
