Southampton Water

Southampton Water is an extremely popular area for yachtsmen because it offers sheltered cruising in nearly all weather conditions, while the Hamble and Itchen Rivers are perfect for leisurely exploration.

As one of the country's busiest and most successful deep-water ports, Southampton is a natural choice for a wide range of customers and trades, with facilities to handle virtually any type of cargo. Its natural deep-water harbour and unique double tide allow unrestricted access for the world's largest vessels.

ABP Southampton, in its role as the Statutory Harbour Authority for Southampton Water, has a strong commitment to protecting the local environment and plays an active role in ensuring that a balance of activities can be maintained, allowing port operations, recreational sailing, and wildlife to co-exist.

In addition to its varied commercial activities Southampton Water is a haven for yachts and leisure craft, and ABP strives to preserve the safety of all users including recreational boat owners as they sail the waters of the Solent.

Keep your VHF tuned to Ch 12, the Port working frequency, and listen for traffic information from the Harbour Master’s Operations Room, Call Sign 'Southampton VTS' (Vessel Traffic Services). The VTS Centre guards Ch 9, 12, 14, 16, 20 and monitors Ch 71 and 74.

The following extracts from the Yachtsman’s Guide to Southampton Water and its Approaches, and Southampton Notice to Mariners No. 2 and 3 of 2014, are reproduced with the permission of ABP Southampton.

Facts to keep in mind: The number of large commercial ships serving the Port of Southampton and the number of recreational craft afloat in local waters is increasing. Most commercial vessels you meet will have a ABP Southampton Pilot on board regardless of the ship's flag. They will be working on and listening to VHF Ch 12.

Most large ships travel at a speed of between 10-15 knots whilst in the Solent and Southampton Water. The lower limit will vary from ship to ship and is 'as safe navigation permits'. For various reasons, ships travel faster than you might think, even in congested areas. Light, partially loaded or unevenly trimmed ships may require to maintain a higher 'as safe navigation permits' speed in order to remain under full control.

It takes less than 10 minutes for a fast ship to reach you from the visible horizon in clear weather, and in hazy conditions it takes a lot less. At 10 knots, a ship travels 1 nautical mile in six minutes; at 15 knots it takes only four minutes. Large deep draught ships cannot easily avoid small craft in narrow channels; it is up to you to stay clear.

A ship that is slowing down does not steer well; it needs the propeller action on the rudder to respond. When the ship's engines are put 'full astern', its manoeuvrability will be affected. Remember that it takes time and considerable distance for a ship to stop.

There are numerous other small vessels operating within the Port of Southampton. Watch out for ferries, hydrofoils, tugs towing barges, especially at night, when unlit barges may remain invisible.

What can you do? Avoid sailing in the main navigational channels and fairways, especially in poor visibility. Obey Rule 9 of the ColRegs for conduct in narrow channels by keeping to the starboard side of the channel and crossing only when this does not impede the passage of a large vessel that can safely navigate only within the narrow channel.

Do not underestimate the speed of ships. If your boat is slow, allow sufficient time to take effective evasive action in the vicinity of large ships.

Be visible. At night make sure your navigation lights can be seen. If you see the navigation lights of a vessel and you think you haven't been seen, get out of the way. Remember, from the bridge of a loaded container ship or large tanker, the Master or Pilot will lose sight of you a third of a mile ahead, although you can see the ship at all times!

Keep watch at night. Even on a clear night you will have difficulty seeing a big ship approach. Remember that your lights will not be easily spotted from the ship. Watch the ship's lights. If you see both sidelights, you are dead ahead - move out fast! Be aware that ships alter course at West Bramble and Calshot.

Know whistle signals. Five or more short blasts on the whistle is the 'Keep Clear' signal. Check and see if it is for you - and if it is - give way. Three short blasts means 'My engines are gong astern'.

Know flag signals and shapes.  A large ship displaying a cylinder on her yardarm during the day, or three red lights in a vertical line at night, indicates the ship is severely restricted in her manoeuvrability so give her a wide berth.

If you believe you have not been seen or you are unsure of a ship's intentions, call them on Ch 12, then shift to a working frequency (6 or an alternative) for inter-ship safety messages

Safety in small vessels: A speed limit of 6 knots (over the ground) applies to all craft proceeding north of the imaginary line drawn from Hythe Pier through the Weston Shelf buoy to the Weston Shore unless granted an exemption by the Harbour Master.

Although considered to be sheltered waters, Southampton Water and the Solent can be extremely hazardous. The six mile stretch of Southampton Water is exceedingly busy and has, on average, 70,000 commercial vessel and ferry movements per year. Mariners in 'small vessels' are therefore reminded of the following requirements:

If not confined to the fairway, they should not use the fairway so as to obstruct other vessels which can only navigate within the fairway.

When crossing the fairway, they should do so at right angles and not diagonally. When crossing a fairway or turning they should not stop or slow down so as to cause obstruction/damage to any other vessel. As a general principle, they should navigate on the correct side of the fairway.

Southampton VTS makes succinct Traffic Information Broadcasts as follows:

  • 0610 to 2210 daily all year round

The broadcasts will be made every 2 hours from 0610 until 2210 (inclusive) on VHF Ch 14, subject to operational requirements, and will be preceded by a broadcast made on VHF Ch 12.

Information given in these broadcasts will include:
• Current and expected movements of significant vessels in the area.
• Weather and tide readings with current trends at Dock Head, Southampton.
• Navigational Warning in force.
• Any other information relevant to navigational safety.

The Southampton VTS website at www.southamptonvts.co.uk contains much useful information for mariners in small vessels and regular use is recommended.
