The Wreck of Pennon, off the Scottish West Coast, is a proper dive, a deep chill that invigorates you from the moment you hit the water. It’s an honest, humbling experience, and one we absolutely love. You descend onto a cargo ship that met its end during World War I, and there's a tangible sense of history down there. The wreck itself is reasonably intact, offering plenty to explore. We particularly enjoy the bow section, often home to decent-sized conger eels peering out from gaps in the plating, a real treat to spot. Visibility can be a mixed bag, as it often is in these waters, but when it clears, the details of the ship emerge beautifully from the gloom. You’ll see schools of saithe swirling around the superstructure and the occasional inquisitive common seal making a fly-by if you’re lucky. We always recommend a good dive light; it makes a huge difference in picking out the smaller nudibranchs and anemones that have colonised the metalwork. It’s a dive for those comfortable with colder water and a bit of current, a genuine adventure for the experienced diver rather than a gentle cruise.
