    StandoutExceptional marine biodiversity

    Diving the Marie Marguerite is a proper Cornish adventure, one we often talk about over a pint afterwards. Dropping to 46 metres, this isn't a dive for the faint-hearted, but the reward is a beautiful, intact sailing vessel that truly tells a story. We love tracing the deck, imagining her final moments, and seeing how the ocean has embraced her. The stern is our favourite spot, often shrouded in a shoal of pout, their eyes reflecting torchlight. You can peer into the holds, sometimes finding conger eels lurking in the shadows, or a solitary lobster waving its feelers from a crevice. The auxiliary engine is still there, a solid testament to her past life, and the visibility, while typically Cornish (meaning, prepare for green), often gives you just enough scope to appreciate her sheer scale. It’s a dive that suits experienced wreck enthusiasts who appreciate history and don't mind a bit of a current; often best timed for slack water on a neap tide for the most comfortable exploration.
