Large vessels
7.—(1) Before any large vessel proposing to transit the bridge enters Great Yarmouth Port—
(a)the harbour master must consider whether any safe alternative manoeuvre for the vessel would be practicable in the event that the bridge does not open to allow the vessel to transit it; and
(b)GYPA will consider whether it is able to arrange a suitable emergency berth for the vessel as part of the pilotage plan for its passage through Great Yarmouth Port.
(2) If, prior to any large vessel proposing to transit the bridge enters Great Yarmouth Port, the harbour master considers under sub-paragraph (1)(a) that no safe alternative manoeuvre would be practicable and GYPA is unable to arrange under sub-paragraph (1)(b) a suitable emergency berth, the undertaker will open the bridge before the vessel enters Great Yarmouth Port.
