YakAttack

TowNStow Bunkster

bunk-style platform cart TNS-1002

The best-documented cart in this database, and the only one we found that publishes capacity honestly — as three numbers for three different terrains instead of one flattering headline. Bunk pads cradle the hull properly. The trade-off is explicit: the standard wheels are for hard surfaces, and YakAttack says so rather than pretending otherwise.

Capacity by terrain

This maker publishes capacity honestly — as separate figures for separate conditions rather than one flattering headline. We calculate with the lowest.

Documented failure modes

What owners actually report going wrong, with an evidence grade on each. This section exists because most reviews omit it.

Straps are not included

low severity 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 severity 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.

How it pairs with kayaks we hold

Evaluated on hard-packed ground with no extra gear — a deliberately generous baseline. Add your real gear load in the finder and some of these will change.
