The Dutch Safety Board has issued an interim warning to the fishery sector for beam trawlers with a length of less than 24 metres. Investigations completed to date into the very serious occurrences involving the trawlers UK-165 in the autumn of 2019 and the UK-171 in the autumn of 2020 reveal that beam trawlers with a length of less than 24 metres can become extremely unstable in an asymmetric loading condition.
An asymmetric loading condition occurs for example if fishing gear is suspended from the outrigger boom on one side of the ship, and not on the other. In that situation, the ship no longer floats upright in the water, but adopts a permanent list. This can have such serious consequences for the stability of the ship that it can lead to capsizing and sinking.
