Plymouth Breakwater

Breakwater · Salt water · in The Cornish and Devon coasts

A 1.5-kilometre detached stone breakwater lying across the mouth of Plymouth Sound, with deep water on the seaward side, a rubble apron, and the sheltered Sound behind. Not connected to land: it is reached by boat only.

Safety: boat safety — can cause serious injury or death. 4 more points apply here.

What each one does, and what reduces it ↓

FishingHQ describes what this place is. It does not say whether you may fish it: access rights, permits, licences, byelaws, closures and protected areas all apply, all differ and all change. Who to ask is below.

What you can catch here

Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

What these strengths mean

Repeatedly reported: Several independent public accounts. Enough to say it happens more than once; not enough to call it a fishery.
Recorded here: At least one credible public account of this species being caught here. That is all it means.
Places, catches and sources are counted separately: A fish documented once at each of six marks is still documented once at each of six marks. Breadth is reported as a place count and never raises the strength, and sources are deduplicated across places so one publisher covering a whole coast counts as one.

How people fish it

Practised here: Sea fishing, Kayak fishing.

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

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.
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.
Spinning
Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.

The ground and the water

The ground: A 1.5-kilometre detached stone breakwater lying across the mouth of Plymouth Sound, with deep water on the seaward side, a rubble apron, and the sheltered Sound behind. Not connected to land: it is reached by boat only.
Exposure: Built to take the full south-westerly swell into the Sound and does so. The landward side is the most sheltered deep water on this coast, which is the entire reason the structure exists.
Depth: Deep on the seaward face and in the entrances; moderate and sheltered inside.
Tide and flow: Streams run along both faces and through the eastern and western entrances either side of it.

Through the year

Pollack and wrasse over the structure year-round with a warm-season peak, mackerel and bream in summer, conger at night, bass from spring to autumn.

Safety

Boat safety — Can cause serious injury or death

The structure is detached and reached only by boat, has no shelter, no exit and no easy landing, and lies across the swell entering the Sound. A change in conditions strands people on it or prevents recovery.

What reduces it: Treat any visit as a boat operation with a weather window rather than as a fishing trip, do not land in a swell, and have a plan for conditions deteriorating while you are on it.

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.

Cliffs and rock platforms — Can cause serious injury or death

Atlantic groundswell arrives from storms thousands of miles away, on days that are locally calm and sunny, and it comes in sets in which one wave runs far higher than the rest. Anglers are swept from rock platforms that had been dry for twenty minutes, into deep water with no shelf to climb out onto and frequently with a long, hard climb back to the access path.

What reduces it: Check the swell forecast rather than the wind forecast; watch any mark for a long period before committing, and assume the sets you have seen are not the largest; never fish rock alone; wear a buoyancy aid; and plan the exit for the sea state you might have rather than the one you arrived in.

Worse when:

Any Atlantic swell forecast on the north coast, regardless of local wind
Rising tide, which brings the sets progressively higher up the platform
Descents that are hard to reverse, wet rock and weed, and darkness
Stretches with no mobile coverage, where raising the alarm is not possible

Moving water and currents — Can cause serious injury or death

The north coast's surf beaches carry strong rip currents, which run seaward through gaps in the sandbars and can take a wading angler off their feet and out beyond the surf line faster than they can walk back.

What reduces it: Do not wade deep in surf; learn to identify the calmer, darker, less-breaking channels that mark a rip and stay out of them; and if caught, do not swim against it — swim across the current parallel to the beach until out of it.

Boat traffic and being seen — Can cause injury needing treatment

The entrances either side carry commercial and naval traffic on fixed routes through constricted water.

What reduces it: Know where the channels are, keep clear, and never assume a large vessel can alter course for you.

Rules and access

FishingHQ does not know the current access position here. Shore angling in England is not rod-licensed, but access rights, landowner permission, local authority and harbour byelaws, national and inshore fisheries measures, and site designations all apply and all change. Check the current position with the relevant inshore fisheries and conservation authority, the harbour or local authority, and the landowner before going.

Particular to this water: This is an owned and operated structure. Whether angling is allowed on it, when, from where and on what terms is the operator's decision, is frequently seasonal, and changes without notice.

Who holds the answer:

The Inshore Fisheries and Conservation Authority for the district, which makes and enforces inshore byelaws.
The Marine Management Organisation, for national recreational sea fishing measures in English waters.
The local authority and, where one exists, the harbour authority, for access, byelaws and shellfish classification.
The national fisheries authority for England, for licensing of freshwater and migratory fishing and for fisheries enforcement
The relevant inshore fisheries and conservation authority for the district, which sets and enforces local sea fisheries byelaws
The body managing any marine protected area on the stretch concerned
The local authority environmental health service, for shellfish classification and public health closures
The harbour authority for working harbours and quays
The relevant estuary or river management body, where an estuary carries its own arrangements
The Queen's Harbour Master and the port authority, for navigation and access within the Sound.
