Paddleboard Safety in Busy Harbour Waters

Why harbour water behaves differently

A harbour can look like the calmest place on the coast, and that is exactly what makes it deceptive. Sheltered by walls and piers, the water sits flat and inviting while a ferry, a fishing boat or a workboat moves through it at speed. Harbour traffic is often on a schedule, and the person at the helm may be looking at a berth, a mooring line or a screen rather than at a paddleboard sitting low in the water. From the deck of a bigger vessel, you can disappear entirely behind a bow wave or a bow rail.

Wash is the other surprise. A boat's wake does not stop when the boat passes. It travels, bounces off harbour walls and pontoons, and meets the wash from other vessels coming the other way. You can be standing on glassy water one minute and dealing with confused, chest-high chop two minutes later, with no wind at all to explain it.

Wear a buoyancy aid that will actually hold you

A buoyancy aid is not optional kit in a working harbour. Choose one rated to at least 50 newtons for sheltered water, and consider a lifejacket instead if you paddle in winter clothing, in rough conditions or alone. The difference matters: a buoyancy aid helps you float and swim, while a lifejacket is designed to turn an unconscious face upwards.

• Fit it snugly. If you can pull it over your head by the shoulders, it is too loose to do its job.
• Use the crotch strap. It stops the buoyancy riding up around your ears when you enter the water.
• Wear it zipped and buckled every time. Not on the deck, not in a dry bag, not "just for the flat bit".

Add a whistle clipped to the outside of the buoyancy aid, wear bright colours, and keep a phone in a waterproof pouch on your body rather than strapped to the board. If you become separated from your board, you will want that phone with you.

Pick the right leash for the water in front of you

A leash is a safety tool and, in the wrong place, a hazard. In open water and on exposed coastline, a straight or coiled leash attached at the ankle keeps you with a board that acts as a large, visible float. In a busy harbour full of mooring lines, pontoon edges, submerged chains and crab pot ropes, an ankle leash can snag and hold you under or drag you against a structure.

• Where entanglement is a real risk, use a quick-release waist leash or belt, and know which hand releases it before you launch.
• Never attach a leash to a fixed object — a pontoon cleat, a buoy, a ladder or a moored boat.
• Practise releasing it in shallow water so the movement is automatic.
• An inflatable board that has lost pressure will not float you. Check the pressure before you leave the slipway.

Keep clear of ferry lanes and commercial channels

Ferry lanes and marked channels are working roads. Cross them only when you have a clear view both ways, and cross at right angles and briskly rather than drifting along inside them. If you are paddling in a group, cross together and compactly — a line of boards strung across a channel is far harder for a skipper to avoid than a tight cluster.

Learn the basics of buoyage. Entering a harbour in the UK, red can buoys mark the port-hand side and green cones the starboard-hand side. Keep to the correct side of the channel and stay near the edge, out of the deep water where the big vessels need their room. Never paddle between a boat and the pontoon it is approaching, and give moored vessels a wide berth — their propellers may be turning, and their mooring lines run further out than you think.

If a vessel sounds a signal, treat it as being aimed at you. Several short blasts usually mean doubt or danger, and the skipper may not be able to stop or turn quickly. Move decisively sideways out of the channel and towards the shallower edge. Freezing in place, or turning to paddle along the channel, is the worst response.

Read the tide, the wash and the marks

Harbour mouths funnel tide, and the ebb in a narrow entrance can run far faster than you can paddle against it. A spring tide running out against a fresh wind builds short, steep chop that is miserable on a board. Check a tide table and a wind forecast before you go, and pick your window rather than your enthusiasm.

Plan where you can get out. Slipways, steps and beaches inside a harbour may be usable at one state of tide and a wall of weed-covered stone at another. Look for the exit before you need it, and keep an eye on the tide while you are out so you are not caught by a rising tide against a harbour wall.

Before you launch: a five-minute routine

• Check harbour notices and local byelaws — some areas restrict paddle craft near berths, fairways or slipways.
• Tell someone your route and your return time, and carry a means of calling for help.
• Dress for the water, not the air. UK sea temperatures stay low all year, so wear a wetsuit or dry suit and expect cold shock if you fall in.
• Check your board pressure, leash type, buoyancy aid straps and whistle.
• Scan the water for moving vessels before you stand up, and again before every crossing.

Harbours are wonderful places to paddle — full of history, wildlife and shifting light on the water. Give the working traffic its space, dress for a swim, and you will enjoy them far more, in every season.
