The EU is not going to agree to anything that restricts its current fishing rights, no matter what Theresa May will have you believe
Whilst paragraph 73 of the draft political agreement states that "the United Kingdom will be an independent coastal state", read paragraphs 75 & 76:
75. Within the context of the overall economic partnership the Parties should establish a new fisheries agreement on, inter alia, access to waters and quota shares.
76. The Parties will use their best endeavours to conclude and ratify their new fisheries agreement by 1 July 2020 in order for it to be in place in time to be used for determining fishing opportunities for the first year after the transition period.
