    The Tommeline is a Scapa Flow wreck with a story. She’s a fishing vessel that grounded and sank back in '88, supposedly due to a sleepy watchkeeper. You'll find her sitting upright at 26 metres, largely intact, which always makes for a more immersive dive. What we love about the Tommeline is the immediate sense of scale you get when she looms out of the green. Her wheelhouse is still there, allowing for some straightforward penetration if you’re comfortable. We’ve spent plenty of time exploring the hold, too, often packed with schooling pollack. Keep an eye out for the resident wrasse darting between the deck fittings. Visibility can be hit or miss in Scapa, so we always suggest checking the local conditions before heading out. Our favourite time to dive her is on a slack tide, when you can really take your time and appreciate the details, from the sturdy winches to the propeller at the stern. She’s a great choice for divers keen on wrecks but perhaps not ready for the sheer size of the battleships.
