Easy Choice

Next time you look at a boat in a dealer showroom ask, “What is it made of?” Because how a boat is constructed—the way it floats, rides and faces up to scrapes, sun, water and towing—determines how much maintenance you’ll put intoit and how much value you’ll get out of it.

At Triumph, we’ve never accepted the status quo. When it comes to your hull, we use the toughest material possible—something that’s not porous, fragile or cobbled together with glue or rivets. Something your cousin could T-bone into a dock, and you’d feel sorry for the dock. Something clean and seamless that you can take a baseball bat to and still not seea dent or crack. Try that on any fiberglass or aluminum boat.

Hard Science

ropeline® is both a material and a process.

The material is a custom-compounded plastic consisting of a low-density polyethylene base combined with antioxidants,UV protection and coloration agents.

The process is closed, rotational molding using computer-controlled ovens specifically designed for Triumph boats.

The result is a seamless, dual-wall hull that’s so strong, it’s virtually impervious to cracks, dents and breakup—even inthe toughest boating and docking situations.

It's called ropeline® and only we have it.

Low Maintenance

Roplene hulls are five times more impact-resistant than fiberglass and never need waxing, polishing or gel-coat touch-ups. That means your Triumph will likely be the lowest-maintenance thing in your life.


Roplene allows us to offer a Five to Life™ Warranty—a five-year warranty on all factory-installed components (engine excluded) and a lifetime structural warranty. And we offer a 10-year structural warranty that’s transferable to a second owner.


Roplene hulls are a double-wall of nautical armor that no glued-together hull can match. That means your Triumph is impervious to saltwater, sunlight and humidity, resists fading, blistering and spider cracks, and keeps its new-boat appearance through decades of use and abuse.


Roplene hulls tame waves for exceptionally smooth cruising and absorb both engine noise and wave impact. That means your Triumph gives you a consistently smooth, quiet ride—no matter how big the water.


Roplene hulls deliver maximum fuel efficiency, are nearly 100% recyclable, and generate zero emissions during manufacturing. That means your Triumph is good for both the environment and your wallet.


Not only does Roplene float, but we take the extra step of filling our boats with foam. That means your Triumph far exceeds U.S. Coast Guard requirements for flotation and safety.


The Roplene process produces unmatched hull consistency. That means the weight distribution of your Triumph will be more precise than any other boat. Other boats can vary up to 20% from side to side.

Hull Design

Our engineers start by creating some of the world’s most innovative hull designs and maximizing Roplene’s incredible resilience, strength and shock-absorption. The result is a design that’s both stylish and functional.

Roto Mold

Each design that makes the grade is passed onto our tooling department, where it’s transformed into a state-of-the-art, all-metal mold. Storage boxes, gunwales, transom, hull, deck cap—everything is molded into a single, seamless piece.


The mold is partially filled with a charge of powdered Roplene, then moved into our 500°F oven, where it’s rotated while the entire oven rocks. As the heat penetrates the mold,the powdered material starts to melt and stick to the interior surfaces. This process continues until layers build up and fuse into a single, seamless piece. Each second of the process is monitored by advanced sensors and fine-tuned by a sophisticated computer program.


Once the computer confirms that the cooking process is complete and all material is properly distributed, the mold moves to the cooling process. During cooling, the mold is precisely rotated while the computer program continues to monitor the process, controlling the cooling rate and ensuring a precise, high-strength boat from bow to stern.


After separating the mold’s two halves and removing the nearly completed boat, we inject high-density foam into the transom, hull, deck sidewalls and interior cavities—far surpassing U.S. Coast Guard requirements for both foam quality and volume.


Finally, production teams double-check installation against master patterns and templates. Our CNC router forms decks, hatches and other parts to hair’s-breadth tolerances, and we pressure-test fuel tanks twice to ensure airtight integrity. Our electrical systems feature corrosion-resistant, solder-coated copper wire, along with sealed terminals and connectors for trouble-free service. And we document and inspect every step in the process again to ensure a lifetime of carefree enjoyment.
