1

Access Channel

See "Channels" sub-section below.

2

Accretion

Gradual build-up of marine sediment. This reduces the navigable depth and width, and the depth of moorings, and maintenance dredging may be required to restore it.

3

Beneficial Re-Use

The use of dredged materials in places where the dredge is of benefit to the new location. A "Beneficial Use" charge is made and licences are required.

4

Berth

i) Where a boat may be moored or its place in port, dock or marina.

ii) A bunk or bed, a sleeping place on a boat.

5

Boatyard

A place with shore facilities where boats are built, maintained, repaired or stored.

6

Buoy

7

Candidate Special Area of Conservation. (cSAC)

An area under consideration as a "Special Area of Conservation" designated under the EC Habitats Directive (92/43/EEC) for its conservation value.

Areas of land, freshwater, estuaries or sea designated by the UK government to comply with the requirements of the EC Habitats and Species Directive. To conserve natural habitats and wild flora and fauna, which are considered rare or endangered and are recognised as being under particular threat. Nationally implemented under the Habitats Regulations, 1994.

8

Capacity - Boats - of River

Upper numerical limit of craft, moored or dry sailed, which can be accommodated with regard to congestion, safety and the environment.

9

Capital Dredge

Material arising from the excavation of the seabed, for navigational purposes in an area or down to a level (relative to Ordnance Datum) not previously dredged during the preceding 10 years.

After 10 years material is deemed to have been compacted and not suitable for disposal at sea and a beneficial use needs to be found. Almost all Hamble marinas, quays and piers have been previously dredged.

15

Dredging

Removal of sediment etc. by mechanical means, from the bottom of a body of water - normally to increase depth to facilitate navigation.

16

Dry Sailing/Sailed

A boat which is kept ashore and launched only when required for use but without an allocated mooring in the River. It may be of any size but normally applied to boats, typically 20' to 30' long.

17

EC Birds Directive

18

Erosion

Loss of material from river bottom or banks by a current, wind generated waves or wash.

22

Habitats Directive

The Habitats Directive (Council Directive 92/43/EEC of 21 May 1992) requires EU Member States to create a network of protected wildlife areas, known as Natura 2000, across the European Union. This network consists of Special Areas of Conservation (SACs) and Special Protection Areas (SPAs), established to protect wild birds under the Birds Directive (Council Directive 79/409/EEC of 2 April 1979). These sites are part of a range of measures aimed at conserving important or threatened habitats and species.

30

Main Channel

See "Channels" sub-section below.

31

Maintenance Dredge

Material arising from an area where the level of the seabed to be achieved by the dredging proposed is not lower (relative to Ordnance Datum), than it has been at any time during the preceding 10 years,

or

Material arising from an area for which there is evidence that dredging has previously been undertaken to that level (or lower) during that period.

32

Manoeuvring area

Area designated to allow manoeuvring, waiting or turning of vessels of significant size in relation to the width of the channel.

51

Port Marine Safety Code

The Port Marine Safety Code, published by the Department of Transport, introduces a national standard for every aspect of port marine safety. It derives from the Health & Safety At Work Act and it aims to improve safety for those who use or work in ports. It establishes a measure by which harbour authorities can be accountable for the legal powers and duties which they have to run their harbours safely.

Though the Code is non - statutory it is not optional either - harbour authorities are expected to work to achieve the agreed standard by implementing its requirements.

58

Sediment transport

The transport of sediments (eg. river deposits, sand, mud gravel etc.) by the natural flow of water.

59

Self-scouring

An area that remains at fairly constant depth as little or no accretion occurs. This is due to the strength of the flow, generally tidal flow on the River Hamble, in that particular area.

60

Siltation

Accretion of silt or fine material.

61

Sites of Special Scientific Interest (SSSIs)

Site notified by English Nature under the Wildlife and Countryside Act 1981 for its importance to by reason of the flora, fauna, geographical or physiographical features.

62

Solent European Marine Sites (SEMS)

The Solent contains 7 international nature conservation sites: there is one maritime Special Area of Conservation (SAC); three classified (i.e. designated) Special Protection Areas (SPAs) and three Ramsar sites. These designations have varying levels of overlap. The areas within these designations that lie below Highest Astronomical Tide (HAT) have become known collectively as the Solent European Marine Sites (SEMS).

63

Special Area of Conservation (Maritime)

or SAC

A site designation specified in the Habitats Directive. Each site is designated for one or more of the habitats and species listed in the Directive. The Directive requires a management plan to be prepared and implemented for each SAC to ensure the favourable conservation status of the habitats or species for which it was designated.

64

Special Protection Area (SPA)

67

Tender

A small rowing or outboard motor boat used to gain access to a moored boat.

68

The Crown Estate

The Crown Estate's primary role in the Solent is that of a major landowner. The Commissioners have a duty to maintain and enhance the capital value of the estate and income obtained from it. This is done by leasing land or granting easements, or issuing licences.

Guiding legislation:

-The Crown Estate Act 1961;

- Territorial Sea Act 1987 (Land ownership);

- Continental Shelf Act 1965 (rights to natural resources).

69

Through Traffic

Vessels passing a location but not stopping or mooring there.

70

Walk Ashore Moorings

Moorings where the crew can walk ashore without needing a tender. Term often means a marina berth.

71

Wash

Wave motion caused by the passage of a vessel through water.

1

Channel -

All Types:

eg. Access, Fairway, Main Channel or Secondary Channel

A channel used for navigation, marked as such and set aside for navigation. It must conform to certain safety criteria.

Ownership of the seabed is vested in the Crown. There is a presumed public right to navigate on all tidal waters that takes precedence over the rights of the owner and may only be altered by Act of Parliament.

The right to navigate is simply a right of way and is a right to pass and repass and to anchor, similar to rights on a public road on land.

(Right to anchor rescinded on the Hamble).

2

Access Channel

A channel to allow vessel access to moorings or landings.

Note:-

Access channels should be short or limited in length to allow decisions to be easily made by skippers regarding rights of way, passing and manoeuvring before entering the channel and allowing vessels to manoeuvre or back out from the channel should it be necessary to give way to another vessel.

3

Main Channel

Primary and preferred thoroughfare for passage of vessels and particularly for 'Through Traffic'.

a. The River has a main navigational channel throughout its navigable length.

b. Capable both in depth and width to allow the safe movement of vessels. (Width not less than 50 metres but reducing after Hamble Yacht Services and even more reduction after the A27 Road Bridge and in the Upper Hamble)

c. Shall carry the correct navigational marks as agreed with Trinity House.

4

Secondary Channel

A smaller non-preferred channel which normally runs parallel to the main channel and allows smaller or slower boats to keep away from the main channel and its traffic.

Secondary Channels shall:-

a. Have sufficient depth to allow the passage of vessels with average draft.

b. Have a defined entrance and exit point that is safe.

c. Deliver traffic to a safe area of navigation and not lead a vessel into difficulty. Normally would have direct access to the main channel at the point of entry and departure. Consideration given to navigating in limited visibility or darkness.

d. Vessels of average size must have sufficient room to pass and manoeuvre.
