South of the moors the water changes character entirely. Deep-water marinas, proper salt, long seasons afloat and boats that genuinely go to sea — a different survey from a Bristol Channel mud berth, with a different set of things worth worrying about.

Where surveys are carried out

Plymouth — Queen Anne's Battery, Sutton Harbour, Mayflower, Plymouth Yacht Haven and the Tamar
Dartmouth and the River Dart — Darthaven, Noss on Dart and Kingswear
Brixham, Torquay and Torbay
Exmouth, Exeter and the Exe estuary
Falmouth — Port Pendennis, Falmouth Marina, Mylor and the Fal
Padstow, Fowey, Salcombe and the smaller harbours
Poole Harbour and Dorset — Poole Quay Boat Haven, Salterns and Cobb's Quay

What is different about surveying boats here

Salt water, full time

These boats live in properly saline water, often afloat year-round, and it shows in ways a Bristol Channel boat does not.

Galvanic activity is aggressive. Anodes waste faster, dezincification of bronze skin fittings and seacocks is more common, and shore-power-related corrosion in busy marinas is a real problem — particularly on aluminium hulls, where a single bad shore connection or a neighbouring boat's wiring fault can remove significant metal in weeks. Bonding, galvanic isolators and isolation transformers all get proper attention on an alloy boat here.

Osmosis has had every opportunity. A GRP hull kept afloat in warm salt water for thirty seasons, with only short winter periods ashore, is the classic candidate. The important point — and it catches out a lot of buyers — is that a boat lifted the day before a survey reads high everywhere, so a single moisture figure means very little. What matters is the pattern of readings across the hull, how long she has been ashore, and whether the laminate sounds solid. There is a full explanation in osmosis in GRP boats, including what treatment actually costs and when it is not worth doing.

Boats that actually go offshore

Devon and Cornwall boats cross the Channel, race, and go to Biscay and Brittany. That raises the stakes on the parts of a survey that a river boat can be relaxed about:

Standing rigging. Age and history matter more than appearance. Undocumented rigging over about ten years old will attract a replacement recommendation regardless of how it looks — budget £3,000–£5,000 on a 38-footer. Chainplates and their bedding get particular attention; masthead and upper rigging need the rig out or a climb, arranged separately.
Steering and rudder bearings, and rudder stock condition — offshore, a rudder failure is a different kind of problem.
Skin fittings, seacocks and hose runs, and whether there are seacocks on every below-waterline penetration.
Watertight integrity — companionway arrangements, cockpit drainage, locker seals, hatch and window condition.
Ground tackle, windlass installation and its backing.
Gas and electrical installations, which insurers scrutinise more closely on offshore-used craft.

Larger craft, and the 60 ft limit

There are more big boats down here. Infinity Marine surveys vessels up to 60 ft. Above that, or for specialist craft — multi-engine high-performance boats, or historic classics needing a dedicated specialist — you will be told straight away and pointed towards someone appropriate. That is a better outcome for you than a stretched survey.

Broker-heavy markets

Plymouth, Dartmouth and Falmouth have busy brokerage. Two practical points. First, ask the broker in writing, well ahead, to have the boat properly prepared — lockers emptied, sole boards up, bilges pumped, engine bay clear, hull washed off immediately after lifting. There is a form of words you can send them in how to prepare your boat for a survey. Second, use a surveyor with no connection to the broker selling you the boat. A recommendation from the person taking the commission is not independent advice, however well-meant.

Travel, and how to reduce it

This is the honest bit. Coming from Bristol or Minehead, Devon and Cornwall involve real travel, and it is quoted by distance rather than hidden in the rate. Two ways to reduce it: ask whether anything else is being surveyed nearby that week, since the saving from combining trips is passed on; and be flexible on dates, because a trip already planned to Plymouth costs you very little extra to join.

If travel makes the total uneconomic for a small vessel, you will be told so rather than quoted regardless. For a £6,000 dayboat in Falmouth, a local surveyor is the sensible answer and saying so costs nothing.

Thirty years across all four materials

Jon Fairman has spent thirty years building, repairing and engineering boats in GRP, wood, steel and aluminium. On a coast with everything from a modern alloy fast cruiser to a 1930s wooden gaffer, that breadth matters — the four materials fail in completely different ways, and a surveyor who only really knows fibreglass will walk past problems on the other three. There is more on that in how each hull material fails.

Boat in the far South West?

Travel is quoted honestly by distance — and where two or more vessels can be seen on one trip, that saving is passed on. If you know of another survey happening the same week nearby, say so.
