What Hull Materials Are Used In Sea Eagle Boats?

Sea Eagle uses two different rugged hull materials in their inflatable boats, kayaks, canoes, and boards. A moderate-pressure, 33 or 38 mil PolyKrylar (K80 PVC) fabric is used in their smaller, lighter boats and a high-pressure, 36 mil 1000 or 2000 denier polyester-reinforced fabric in high-performance boats.

Both materials are incredibly rugged but not equally durable. I’ll cover both of these materials and the manufacturing process used in making Sea Eagle boat hulls.

Sea Eagle Moderate-Pressure Fabric Hull Material

The Sea Eagle inflatable Sport Kayak hulls are made of a tough and durable Polyvinyl chloride (PVC).
The Sea Eagle SE 330 and SE 370 inflatable Sport Kayaks

Sea Eagle uses moderate-pressure fabric for the hulls of their Sport Kayaks and Motormount Boats.

The Sport Kayaks and Motormount Boats are designed for calm to mild whitewater use and the Motormount accepts a small motor. Their intended use requires a rugged hull material and their designs are achieved without the need for high inflation pressures.

Sea Eagle K-80 Polykrylar (K80 PVC), a tough and durable Polyvinyl chloride (PVC) material that is perfectly designed to meet the needs of these boats.

The smaller Sea Eagle 330 Inflatable Kayak has a hull made with the thinner 33 mil Polykrylar (K80 PVC) material while the larger Sea Eagle 370 and the Motormount Boat hulls are made with 38 mil K-80 Polykrylar.

Perfect for High-Frequency Electric Welding

The sheets of K-80 Polykrylar used in the production of Sea Eagle boats are uniform throughout for clean, perfect high-frequency electric welding. It welds smoothly and evenly to ensure the highest quality weld where the two pieces permanently bond as one.

Remarkable Tear-Resistant Fabric

The extraordinary tear-resistant properties of K-80 Polykrylar provide equal tear resistance in every direction. This material is extremely durable. Punctures are rare but should you receive a small hole, the material will not “zipper” and run like materials used in other inflatable boats.

Extra-Thick Hull Material

When comparing boats of equal size, Sea Eagle’s hull material is thicker than any other inflatable boat. In most cases, Sea Eagle’s K-80 Polykrylar hull is thicker than many more expensive PVC-supported polyester fabric materials.

Additives for a Longer Service Life

K-80 Polykrylar is formulated with special additives that protect against ultraviolet (UV) rays, salt water, gasoline, oil, and other chemicals to guarantee a longer service life.

Sea Eagle even backs up the long life of their boats with a 3-year limited warranty against manufacturer’s defects on which you can buy an additional 3-year extended hull warranty. They are extremely confident in the long life of their hull materials.

Sea Eagle High-Pressure Fabric Hull Material

The full Sea Eagle lineup of inflatable boats, kayaks, canoes, and boards that have 1000 denier, reinforced, high-pressure fabric hull material (Explorer Kayaks, RazorLite Kayaks, FastTrack Kayaks, Travel Canoes, Frameless Fishing Boats, Fishing Skiffs, Sport Runabout Boats, FoldCat Pontoon Boats, FastCat Catamarans, PaddleSki Catamarans, and Boards and SUPs).

Sea Eagle uses extremely rugged, high-pressure fabric for the hulls of the following high-performance inflatable boats and boards:

The hull fabric of these boats and boards has three layers of protection. It’s made of a tremendously strong 1000 denier woven base cloth that is reinforced with a special polymer coating on both sides for extra durability and a waterproof, airtight seal. A few of Sea Eagle’s boats go over and beyond with reinforced sections of 2000 denier or two layers of 1000 denier material for double layer protection.

Benefits of Sea Eagle’s 1000 Denier, Reinforced, High-Pressure Hull Material

Nearly Indestructible Supported Fabric

Sea Eagle’s hull material starts with a base tightly woven 1000 denier base cloth that is coated on both sides with a special polymer then fed through high-pressure rollers to force the coating into the fabric creating an extremely tough waterproof and airtight material.

Omni-Directional Fabric Strength

The fabric material of Sea Eagle’s high-performance boats and boards is tear and puncture-resistant. The fabric is engineered to withstand severe impacts with sharp objects without puncture or tear.

Hot Air Welded and Quadruple Overlap Seams

Sea Eagle uses hot air welding to permanently bond the seams on many of their boats and boards. These seams are further reinforced with seam tape on both sides of the weld.

In areas of the hull where welding isn’t possible, Sea Eagle uses a quadruple overlap seam. This seam is made with an additional layer of reinforcement material above and below the seam for a total of 4 layers. With a material thickness of 36 mil, the 4 layers are nearly 144 mil thick.

Additives for a Longer Service Life

Sea Eagle’s 1000 denier, reinforced, high-pressure fabric is formulated with special additives that protect against salt water, ultraviolet (UV) rays, gasoline, oil, and other chemicals to guarantee a longer service life.

Sea Eagle even backs up the long life of their boats with a 3-year limited warranty against manufacturer’s defects on which you can buy an additional 3-year extended hull warranty. They are extremely confident in the long life of their hull materials.

Survives Hull Durability Tests

Sea Eagle’s 1000 denier, reinforced, high-pressure hull material can survive a beating from the claw end of a hammer. Cinder blocks just bounce off it when dropped. Being run over by a Jeep won’t harm the inflated hull either. No leaks formed in the hull’s fabric during these durability tests and the seams remained intact.

Wrapping-Up

Sea Eagle has been making durable, safe, and well-engineered boats since 1968. They even inflate and factory-test each inflatable boat, kayak, canoe, and board for a full 24 hours before it’s shipped to its owner.
