Fit check

Old Town Sportsman BigWater PDL 132
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 to watch

  • Positioning matters on this boat: PDL drive console mid-hull.

    • Stern rudder.

What works

  • Load margin is comfortable at 69% 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 62.6 kg, not the 53.1 kg hull figure.

Boat only

62.6 kg / 91 kg

As it comes off the roof bars, nothing aboard.

69% — Comfortable. Under 70% of rated capacity. Headroom for gear creep, rough ground and shock loading.

Light day kit

70.6 kg / 91 kg

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

78% — Moderate. 70–85% of rated capacity. Fine on firm ground. Watch for frame flex over kerbs and roots.

Loaded fishing rig

82.6 kg / 91 kg

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

91% — Near maximum. 85–100% of rated capacity. No margin for shock loads. Avoid drops, kerbs and stairs.

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

How to position a cart correctly

Across the ground you cross

Verdicts recalculated for each surface at the light-day-kit load. Terrain scores are our declared judgement scale from wheel geometry and construction — not instrumented pull-force testing.

Hard-packed dirt track — Recommended
Grass / turf — Recommended
Gravel or shingle — Recommended
Wet / firm sand — Recommended
Deep dry soft sand — Recommended
Mud / tidal flat — Recommended
Steps or a steep bank — Recommended

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.
