The relevant bit of wording in that document is this:-
Group 8, Items 1 and 2 are based on Principal VAT Directive (Directive 2006/112) Article 148:
148 Member States shall exempt the following transactions:
a.the supply of goods for the fuelling and provisioning of vessels used for navigation on the high seas and carrying passengers for reward or used for the purpose of commercial, industrial or fishing activities, or for rescue or assistance at sea, or for inshore fishing, with the exception, in the case of vessels used for inshore fishing, of ships’ provisions;
b.the supply of goods for the fuelling and provisioning of fighting ships, falling within the combined nomenclature (CN) code 8906 10 00, leaving their territory and bound for ports or anchorages outside the Member State concerned;
c.the supply, modification, repair, maintenance, chartering and hiring of the vessels referred to in point (a), and the supply, hiring, repair and maintenance of equipment, including fishing equipment, incorporated or used therein;
