Cotentin Wreck
A dynamited navy tug in 5–10 m off Illa Mateua
Area photo: Enric · CC BY-SA 4.0
A French Navy tug that ran aground off Illa Mateua on 8 September 1963 while under tow, was dynamited afterwards, and now lies in 5 to 10 m in the northern part of the cove. Catalan sources name the vessel Cotentin; the dive centres and the catalogue list the site as El Constantine or Constantin.
Also known as El Constantine, Constantin.
Where it is and how deep
42.1149° N, 3.1638° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The remains lie in the northern part of Cala Illa Mateua, in 5 to 10 m of water; the catalogue frames it as an easy dive with an average around 12 m. That depth is the whole character of the site — nothing about it asks for a long descent or a tight gas plan, and it leaves time to work over the wreck slowly and still finish on the shallow rock around it.
What is down there is what the dynamite left. The tug was broken up where it grounded, so the dive is a search over structure rather than a tour of a hull, and the operator describes the result as an easy and attractive itinerary. It is the shallow wreck of this coast, and the one an entry-level certification covers without any special arrangement.
The wreck
- Vessel
- Cotentin
- Type
- French Navy tug
- Sunk
- 1963
- Cause
- Ran aground after the tow line parted in a north wind; dynamited afterwards
- Lies
- Broken remains in 5–10 m in the northern part of Cala Illa Mateua
The tug was being towed to a port in France to be broken up when the force of the north wind parted the line to the ship towing it. It drifted until it found the coast of L'Escala, where it ran aground on 8 September 1963. It was dynamited later, and its remains are what divers see today. The Catalan record names the vessel Cotentin, while Orca Diving and the catalogue list the site under the local name El Constantine.
