Details: Fishing kayak owners and paddlers with heavy loads now have an award-winning product to transport their kayak. This workhorse cart will transport up to 330 pounds with ease and comes with balloon-style beach wheels that will never go flat. All-terrain wheels (sold separately) can be swapped onto the same frame and increase the carrying capacity to 450 pounds. It is also easy to load and unload the kayak - no kickstands or scupper posts required - and two included security straps prevent the kayak from slipping. Cart is collapsible for storage and can fit into larger kayak hatches. The heavy duty cart is constructed of marine-grade, High-strength, Heat-Treated aluminum alloy for superior strength.
