  • Features

    Commercial grade boat fabric for main construction; Four layers overlapped chamber seam structure (Feature Code: FOS); Keel Center Inner Reinforcement (KCR); Transom Stabilizer & Reinforcement Design (TSR); Hull Stabilizer Bar Structure (HSBS); Additional Seamax special feature includes: Dual Heavy-duty life lines; Heavy-duty boat bumper around the boat and bottom; Heavy-duty D-ring and Towing ring patches.


    4 layers overlap seam finishing is the strongest seam construction standard in the inflatable boat industry. The 2 main chamber fabrics are real-bonded together with ½” overlapping. Extra seam tapes on both sides of chamber to reinforce the main seam. Overall thickness of the 4-layers chamber seam is 5mm in total. Our chamber seam technology gives the boat a longer life time comparing with many others.


    Seamax always focuses on high manufacturing standards. A rigid transom is very important for inflatable boats. Beside using solid birch plywood to build transom, we develop a new standard called Transom Stabilizer Reinforcement (TSR) to help the pontoon to disperse motor vibration and weight. The reinforcement technology extends the overall life time of the inflatable boat.


    Hull Stabilizer Bar (HSB) is designed by Seamax and first applied in an 18ft government boat project. Now Seamax HSB 2.0 is available on every Seamax Ocean T model boat. Located near the front deep V-Hull, the specially made HSB greatly helps to stabilize the boat structure. The tension along the HSB creates an invisible force triangle to stabilize the front Hull and keep the floor in place. Such a triangle inner support for the hull is a great boat add-on feature. A boat with HSB also has a better high speed boating performance.
