YakAttack
TowNStow Bunkster
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.

| Trail / uneven ground | 136 kg (300 lb) | 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. |
| Over a 13 cm (5 in) drop | 91 kg (200 lb) | 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. |

If you launch off sand, buy this configuration from the start — do not buy the hard-surface version and hope.

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.
