Summary

This statutory Merchant Shipping Notice sets out the categorisations of waters in the United Kingdom.

Key Points

  • the notice replaces and augments MSN 1758(M).
  • the changes and additions are shown in bold and italics respectively.
  • the categorisations determine the waters not regarded as "sea" for the purposes of Merchant Shipping legislation (excepting marine pollution).

1. The Annex to this Merchant Shipping Notice sets out the categorisations that apply to waters in the United Kingdom. These categorisations are given statutory force by way of Regulation 2 of the Merchant Shipping (Categorisation of Waters) Regulations 1992.

2. Amendments to Merchant Shipping Notice MSN 1758 and its Annex are shown in bold and additions are shown in italics.

3. The four categories of waters are as follows:

  1. Category A: Narrow Rivers and canals where the depth of water is generally less than 1.5 metres.
  2. Category B: Wider rivers and canals where the depth of water is generally 1.5 metres or more and where the significant wave height could not be expected to exceed 0.6 metres at any time.
  3. Category C: Tidal rivers and estuaries and large, deep lakes and lochs where the significant wave height could not be expected to exceed 1.2 metres at any time.
  4. Category D: Tidal rivers and estuaries where the significant wave height could not be expected to exceed 2.0 metres at any time.

4. These categorisations apply specifically to the operation of Class IV, V and VI Passenger Ships and also determine which waters are not regarded as "sea" for the purposes of regulations made, or treated as made, under Section 85 of the Merchant Shipping Act 1995.

5. Under the Merchant Shipping (Prevention of Oil Pollution) Regulations 1996 it should be noted that "sea" includes any estuaries or arms of the sea.

6. These categorisations should not be confused with classifications for Passenger Ships as designated in the Merchant Shipping

(Passenger Ships on Domestic Voyages) Regulations 2000 which implement the EC Directive on Safety Rules and Standards for

Domestic Passenger Ships.

7. The categorisations shown in the Annex apply at all times of the year unless otherwise indicated. "Summer" means the months of April to October, inclusive, and "winter" means the months of November to March, inclusive.

8. This Notice will come into force on 1 April 2003.
