Notes:

1 Least water depths
The deep-water routes from North Hinder to the traffic separation scheme "Off Brown Ridge"
and from the traffic separation scheme "Off Brown Ridge" to the traffic separation scheme
"West Friesland" and the traffic lanes of the traffic separation schemes "Off Brown Ridge"
and "West Friesland" were c10sely surveyed in the period 1981 to 1986. The least water depth
found in these areas was more than 23 m at LLWS except for one wreck in geographical position
52°46'.17 N, 3°13'.83 E. The least water depth over that wreck found by wire-sweeping was 20.0 m
at LLWS.

(See also the note pertaining to the traffic separation scheme "Deutsche Bucht lightvessel,
western approach".)

2 Least water depths
The deep-water routes from the traffic separation scheme "Off Botney Ground" to the
precautionary area "Friesland junction" and "From North Hinder to Indefatigable Bank via DR1
lightbuoy", the traffic lanes of the traffic separation scheme "Off Botney Ground", the
precautionary area "Friesland junction", and the traffic separation scheme "East Friesland"
were c10sely surveyed in the period 1981 to 1986. The least water depth found in these areas
was more than 29 m at LLWS except for a few patches just north of the parallel 52° N, which
have a depth of 26.5 m at LLWS.

the Approaches to Chesapeake Bay" between the separation lines which connect the following
geographical positions of the traffic separation scheme:

(6) 36°55'.11 N,  75°55'.23 W	(9) 36°49'.52 N,  75°46'.94 W

Notes:

1 It is recommended that the following ships use the deep-water route when bound for Chesapeake
Bay from sea or to sea from Chesapeake Bay: Deep-draught ships (draughts defined as greater
than 13.5 m/45 ft in fresh water) and naval aircraft carriers;

2 It is recommended that a sliip using the deep-water route:

.1 announces its intention 011 VHF-FM channel16 as it approaches Chesapeake Bay Southern Approach Lighted Whistle Buoy CB on the south end or Chesapeake Bay Junction Lighted Buoy CBJ, on the north end of the route;

.2 avoids, as far as practicabie, overtaking other ships ·operating in the deep-water route;

.3 keeps as near to the outer limit of the route which lies on the starboard side as is safe
and practicabie.

3 All other ships approaching the Chesapeake Bay traffic separation scheme should use the
appropriate inbound or outbound traffic lane of the traffic separation scheme "In the Approaches
to Chesapeake Bay".

Application
The route is recommended for use by the following classes of ships of 10,000 tons gross tonnage
and upwards:

(a) tankers carrying oils mentioned in appendix I, annex I to the International Convention for the
Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto
(MARPOL 73/78); and

(b) ships carrying in bulk liquid substances c1assed in categories A and B mentioned in appendices
I and II, annex II, to MARPOL 73/78.


Use of the route

(a) The classes of ships referred to above are recommended to use the route or part of it:

(i) when sailing from North Hinder to North Sea ports of Germany and of the Netherlands
northwards of latitude 53° N and vice versa;

(ii) when sailing between North Sea ports of the Netherlands and/or Germany, except in the
case of adjacent port areas;

(b) The traffjc separation scheme "Deutsche Bucht lightvessel, western approach" should be used
in continuation of the route.

(c) Ships should use the appropriate traffjc lanes of the traffic separation schemes forming part
of the route; ships should follow the recommended direction of traffic flow in the precautionary
areas (indicated by dashed open-outlined arrows in the charts) and ships should, as far as
practicabie, keep to the starboard side of the deep-water routes forming part of the route.

Joining and leaving the route

The classes of ships referred to above when joining or leaving the route:

(a) should do so at the nearest point of the route to the port of destination or departure which
permits a safe passage to or from that port;

(b) should be aware that oil and gas production facilities and mobile offshore drilling units may
