None of the codes below cover Vessels carrying
over 12 passengers. They must be operating in favourable weather
and daylight.
All vessels may operate in their Category and
those below. So for example, a boat that is coded as Cat 4
may also operate in all areas allowed by Cat 6, and Cat 5.
| A summary of the Operating
Areas |
| Cat A |
Narrow rivers and canals where
the depth of water is generally less than 1.5 metres.
|
| Cat B |
Wider rivers and canals where
the depth of water is geerally more than 1.5 metres and
where the significant wave height could not be expected
to exceed 0.6 metres at any time.
|
| Cat 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.
|
| Cat D |
Tidal rivers and estuaries
where the significant wave height could not be expected
to exceed 2 metres at any time. E.g. Solent Category 3.
|
| NDP Code |
A local licensing authority
may permit operation 'no more than 3 miles from land nor
more than 15 miles from the Nominate Departure Point (NDP).
E.g. Solent Category 4
|
| |
|
| Cat 6 |
Within 3 miles of a Nominated
Departure Point (NDP) and never more than three miles
from land when the distance of three miles shall be measured
from the seaward boundary of Cat A,B,C or D waters. Always
in favourable weather conditions and Daylight.
|
| Cat 5 |
Within 20 Miles of a Nominated
Departure Point (NDP) measured from the seaward boundary
of Cat A,B,C or D waters. Always in favourable weather
conditions and Daylight.
i.e. A Cat 5 vessel must return to their NDP.
|
| Cat 4 |
Up to 20 Miles from a Safe
Haven in favourable weather conditions and Daylight.
i.e. A Cat 4 vessel may passage from any 'safe haven'
to any other 'safe haven' within a 20 mile range.
|
| Cat 3 |
Up to 20 Miles from a Safe
Haven.
|
| Cat 2 |
Up to 60 Miles from a Safe
Haven.
|
| Cat 1 |
Up to 150 Miles from a Safe
Haven.
|
| Cat 0
|
Unrestricted Service. |
Further notes:
Whats with the numbers and letters
?
All alphabetical Codes relate to areas within a 'safe haven'
or 'nominated departure point'. (A safe haven is simply a
point of refuge, such as a harbour). They represent actual
geographical areas such as canals, lakes, harbours, etc. They
are essentially there to describe categories of water.
The numerical Codes represent the restrictions upon individual
boats themselves, defining the geographical areas and weather
conditions it may operate in, the equipment it must carry
and the qualifactions the crew must hold. These can be seen
in the chart as decreasing restrictions (from Cat 6 to Cat
0) in the vessels operating areas, allowing them to venture
ever further out to sea.
How do I find out what my Classification is ?
We have created a Classification of Waters database which
includes all of the waters of the UK and their MCA classifaction.
You can easily select your local waters and see its coding
information.
