The online system for booking freight may be straightforward for most companies but when carrying hazardous the system is not smooth. Having to book all journies separately instead of a return journey, which then involves two credit card payments as we are not allowed to open an account with StenaLine as we do not travel frequently enough, obtaining booking references, then having to file hazardous documents, to be then hit with a further hazardous charge, resulting in another two credit card payments. A whole morning to book a return ferry crossing from Cairnryan to Belfast. Not good enough!
