The Heavy Duty Kart uses an adjustable-width bunker bar frame that stops the boat twisting or sliding. It has two height settings, high for odd hulls and low for stability, and two security straps. It folds and the wheels come off for storage. Paddling Magazine named it a 2026 category winner.

KayakDIY take: A bunk-style cart is a good fit for heavy fishing kayaks, and this one avoids scupper stress. For more options, see my fishing kayak accessories guide.
