HMS SEVRA - Cornwall & Devon

The HMS Sevra, down at a comfortable 10 metres, is one of our favourite shallow wrecks in the Falmouth area. We'd call it a perfect second dive or a really solid choice for those newer to wreck diving. She was a factory ship, built in 1929 and then pressed into service as a minesweeper in 1940, only to be sunk by a mine herself that November. Today, she's broken but still recognisable, spread across a sandy seabed. You can see the ribs of her hull, plates peeled back like old tin cans, and a fair bit of machinery still poking out. We love seeing the light play through the gaps, especially on a sunny day. It’s home to plenty of tompot blennies peering from every crevice, dogfish often resting in the sand nearby, and we’ve even spotted conger eels tucked under the larger sections. Given her depth, you get plenty of bottom time to really nose around. Look for the distinct bow and stern sections, which are still somewhat intact. We’d suggest going at slack water, as currents can pick up, especially around spring tides.
