Fit check

Old Town Sportsman 120
with the
YakAttack TowNStow Bunkster

Recommended Inferred— evidence level: No direct fit report exists. Our published rules engine compared measured cart geometry and capacity against measured kayak geometry and loaded weight. Geometry is not the same as a real-world fit.

This pairing works. The load margin is sensible and nothing about the hull or the cart geometry fights you.

What works

  • Load margin is comfortable at 28% of the rated capacity.
  • The contoured bunk pads that cradle the hull suits your hull shape.
  • 30.5 cm (12 in) airless wheels handles hardpack well.

Load margin as you actually load it

Against a planning capacity of 91 kg (200 lb) . Starting point is the rigged weight of 25.4 kg, not the 25.4 kg hull figure.

Boat only

25.4 kg / 91 kg

As it comes off the roof bars, nothing aboard.

28% — Comfortable. Under 70% of rated capacity. Headroom for gear creep, rough ground and shock loading.

Light day kit

33.4 kg / 91 kg

Paddle, PFD, dry bag, water, small anchor. (+8 kg)

37% — Comfortable. Under 70% of rated capacity. Headroom for gear creep, rough ground and shock loading.

Loaded fishing rig

45.4 kg / 91 kg

Crate, battery, fish finder, rods, tackle, catch. (+20 kg)

50% — Comfortable. Under 70% of rated capacity. Headroom for gear creep, rough ground and shock loading.

Gear figures are our standard scenario weights, not measurements of your kit. Swap in your own on the weight calculator.

Documented failure modes for this cart

Reported by owners, not by us. These are not specific to your kayak, but they are what goes wrong.

  • Straps are not included

    low Mfr confirmed— evidence level: The figure or fit statement is published by the manufacturer of the kayak or the cart, in their own documentation, spec sheet or support channel.

    It needs 25 mm (1 in) cam straps and does not ship with them. Budget for two.

  • Standard wheels are useless on soft sand

    medium Mfr confirmed— evidence level: The figure or fit statement is published by the manufacturer of the kayak or the cart, in their own documentation, spec sheet or support channel.

    Not a defect — a stated design limit. The 6.4 cm (2.5 in) tread has nowhere near the footprint needed for dry sand.
