In my experience long distance cruisers are great lovers of the marine environment, whether it be clean seas, marine wildlife or their favourite wild places. If that is indeed true, we’d be the last people to want to cause harm to pristine places, either deliberately or unwittingly. And yet, as I recently learned, the latter may indeed be the case, even though we have no idea at all that we may be doing it. And it’s all down to the critters that hitch a ride with us on our hulls—Invasive Non-Native Species, INNS for short.
