Duncansby Head and the Pentland Firth

Tidal race · Salt water · in The Moray Firth

The north-eastern corner of mainland Britain: Old Red Sandstone cliffs and stacks above a strait roughly ten kilometres wide separating the mainland from Orkney, with an irregular rock bed and sills that force the flow.

Safety: moving water and currents — can cause serious injury or death. 2 more points apply here.

Fish documented nearby, not here

Nothing below has been documented at Duncansby Head and the Pentland Firth itself. Each one has been documented at a named place on the same ground, and the places are listed with it. Treat this as what the water around here holds rather than as a catch list for this mark.

Also documented at neighbouring places

One or two accounts each, on the ground around here. Enough to know the fish is caught in these waters; not enough to say anything about this place.

From the shore

How people fish it

Practised here: Sea fishing.

Methods the sources name for this ground. Each one is explained in full on its own page.

  • Ledgering

    Fishing a bait on the bottom held by a weight, with no float — the simplest way to fish at distance, in depth, or in wind.

  • Float fishing

    Suspending a bait at a controlled depth beneath a buoyant indicator — the most visual, most controllable and most widely applicable method in angling.

The ground and the water

The ground
The north-eastern corner of mainland Britain: Old Red Sandstone cliffs and stacks above a strait roughly ten kilometres wide separating the mainland from Orkney, with an irregular rock bed and sills that force the flow.
Exposure
Open to the Atlantic from the west and the North Sea from the east, and the two seas meet here. There is no shelter anywhere in the strait.
Depth
Deep in the strait with abrupt sills and banks that are the mechanism behind the races.
Tide and flow
Among the fastest tidal streams in the world, exceeding ten knots on springs in places, with named races — the Merry Men of Mey, the Swelkie, the Bores of Duncansby — that produce standing waves, overfalls and whirlpools large enough to be a hazard to substantial vessels, not merely to small craft.

Through the year

Cod, coalfish and pollack over the rough ground with a cold-season weighting; mackerel through the summer.

Safety

Moving water and currents — Can cause serious injury or death

The Pentland Firth races are not a strong current: they are standing waves and overfalls capable of overwhelming vessels far larger than a fishing boat, and they build and disperse on the tidal cycle rather than on the weather. The water a kilometre offshore can be lethal while the shore looks ordinary.

What reduces it: Treat any small-craft activity in the firth as a specialist pilotage problem requiring current tidal stream data and local knowledge, and understand that the shore-based danger here is being tempted afloat by a calm-looking day.

Worse when:

  • On spring tides, when the races are at their most powerful.
  • With wind opposing the stream, which turns fast water into breaking water.

Cliffs and rock platforms — Can cause serious injury or death

Anglers are swept from rock platforms by individual large sets rather than by the average sea, which means the conditions that kill people frequently look survivable for the twenty minutes before they arrive. Wet rock, weed and a swell running onto a sloping platform remove any chance of recovery.

What reduces it: Watch the water for a full set cycle before committing to a position, know the escape route and how long it takes, wear a flotation aid rather than carry one, never fish a platform alone, and treat a rising swell forecast as a reason not to go rather than a reason to be careful.

Cold water shock — Can cause serious injury or death

UK coastal and inland water is cold enough for most of the year to trigger the involuntary gasp and the loss of swimming ability that decides most immersion deaths, and it does so within the first minute, long before hypothermia is relevant.

What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person rather than in a bag, and plan on the assumption that an unplanned entry into the water is survivable only if somebody knows immediately.

Rules and access

FishingHQ does not know the current access position here. Sea angling in Scotland is not rod-licensed, but access rights under the Scottish Outdoor Access Code carry responsibilities, and harbour, local authority, marine conservation and fisheries measures all apply and all change. Check the current position with the Marine Directorate, the harbour or local authority and the land manager before going.

Who holds the answer:

  • The Scottish Government Marine Directorate, for sea fisheries measures in Scottish waters.
  • The harbour authority or land manager, for access to the structure or the ground.
  • The local authority, for shellfish harvesting classification.
  • Marine Directorate of the Scottish Government, for sea fisheries measures, conservation designations and marine licensing in Scottish waters.
  • The district salmon fishery board for the river concerned, which administers salmon and sea trout fishing on each of the rivers entering this firth.
  • The proprietor, estate or angling association that holds the fishing rights, since freshwater and migratory fishing rights in Scotland are private and permission is required.
  • NatureScot and the relevant site management bodies, where a marine or coastal designation affects access or activity.
  • The harbour authority or trust at each port, for access to and fishing from harbour structures.
  • The local authority and the Food Standards Scotland framework, for shellfish harvesting area classification.
  • The Northern Lighthouse Board and the harbour authorities either side, for navigation in the firth.
