DYMON is the Goldilocks solution for today’s larger runabouts and day boats. Most fenders miss the mark–they’re either too small to protect or too bulky to manage. DYMON’s taller profile shields above and below the rub rail without twisting or rolling, and its inflatable design stows flat when not in use. Side-mounted attachment points and the knot-free DREADKNOT™ system lock your fender in place and let you dial in the perfect height – in seconds. For boats 25–35 feet long, it’s the fender that finally feels just right.

Traditional fenders can be challenging with today’s larger boat designs. As styling has evolved, so have the challenges of protecting your hull—tall grab rails have disappeared, rub rails vary in height, and clean topsides leave fewer good places to tie off. That makes old-school fenders hard to position where you actually need protection. And upsizing them just adds bulk you don’t want to deal with.

DYMON sets a new standard. Its taller profile and side-mounted attachment points provide full coverage above and below the rub rail. Dual-line connections keep it locked in position—no twisting, no rolling. And with the integrated DREADKNOT™ system, you get knot-free height adjustments in seconds. Need a small precise adjustment? – no issue.  

Crafted from layered, PVC-coated nylon and reinforced at every seam, DYMON handles UV, salt, and heavy use season after season without leaving marks. The protected high-pressure valve means it keeps its air. And when you're done, DYMON deflates in seconds and stows flat. 

Easy attachment. Big protection. Small footprint. That’s the new standard.
