The weed machine in action – uprooting weeds growing underwater in Penarth Marina. It’s highly manoeuverable and can turn in its own axis.

An unusual craft has been deployed by Penarth Quays Marina to help staff tackle the – literally –  growing problem of underwater weed.

The comparatively warm, still, shallow fresh waters of Penarth Marina have proved to be ideal conditions for the proliferation of large frond-like plants which proliferate beneath the pontoons and moored craft in both of the marina’s basins.

The weed is also encouraged to grow by the oxygen being constantly piped-in from the sea-bed beneath by the Cardiff Bay sub-surface aeration system – intended to improve the water quality.

Manual “weeding” of the marina has proved to be a huge job with several skips being filled  with weed by marina staff – with help from several berth-holders.

This week Quay Marinas are trialing a mechanical system to see if the arduous job can be speeded up. An American-made Truxor weed-cutter to tackle the worst of the weed.

Some of the weeds growing  up from the mud bed of the marina – can be more than 12 feet long.

Truxor is a kind of marine lawnmower which won’t be defeated by the worst of the weeds

The rotating paddle wheels and the weed-cutter attachments seem to be effective at dislodging the worse of the weed which craft can then collect.
