There's no substitute for a strong foundation
A. Constructed by Endurance - 3/4", 7-ply pressure treated plywood through=bolted and screwed to the hat channels to create the strongest seams in the industry
B. Hat-Channel Construction - It all begins with .250 (heavy) and .125 (standard) gauge aluminum hat channels that are 6" wide deck risers. This creates the widest base in the industry and gives our pontoons greater stability without adding unnecessary weight. Combine that with a .190 guage aluminum transom that's through-bolted with up to 20 bolts and footed deck risers that prevent tube fatigue, and you see why Sylvan backs its industry-leading construction with a Limited Lifetime Warranty on every product.
C. Fence & Railing - Features foam backing to prevent rattling and fully welded and anodized railing to add strength. Anodized welds are never painted. It's all backed by a 6-year warranty.
D. Thru-Bolted Transom - Made of up to .190 guage aluminum and supported with up to 20 stainless bolts to handle today's higher horsepower engines.
E. 4-pt Deck to Hull Fusion - Sylvan deck brackets have 4 points of fusion for an extended area of contact with the tube. In addition to providing increased strength and support, this reduces frame twist and racking in rough water and guards against tube fatigue.
