The Roplene® system produces seamless, dual‑wall hulls out of naturally buoyant and incredibly strong marine‑grade polyethylene. Used in the manufacturing of all Triumph boats, this process produces hulls that are so strong they are virtually impervious to cracks, dents and breakup, even in the toughest boating and docking situations. Roplene construction gained the attention of the National Society of Professional Engineers which recognized Triumph with the Best New Product of 1998 award. In 1997, the Roplene system won the North Carolina Governor's New Product Award.
The Roplene construction process benefits the whole planet. Roplene construction uses low‑density polyethylene, which has five times the impact resistance of fiberglass, is significantly less expensive overall, and is almost 100% recyclable. The process produces few, if any, air emissions, compared to open‑face molding (the most common method used to build fiberglass hulls) that is labor intensive and releases regulated emissions. The Roplene process begins with a specially formulated polyethylene compound powder which is poured into a high‑temperature mold. The mold is mounted in a large convection oven and rotated both vertically and horizontally. The oven's heat melts the powder, which forms the boat. The mold continues to rotate during the cooling stage to ensure an even, consistent thickness.
South Pacific Tested
Roplene‑constructed boats were tested for five years in tough South Pacific waters in commercial, rescue and recreational boats before they hit the market in the late 1980s. It's for these reasons that Triumph boats can lay claim to the phrase the World's Toughest Boats®.
