    Let's talk about FPT IV, a wreck that always sparks a bit of debate among our team. It’s a barge, sunk back in ‘89 after losing its tow in rough weather near Selsey Bill and then drifting all the way here. For us, it’s not about grand scale or dramatic drop-offs; it’s about the sheer resilience of something discarded finding a new purpose. At a shallow 11 metres, FPT IV is perfect for divers who want to take their time. You can spend a whole no-deco dive just circling, peeking into its nooks and crannies. We particularly love the way the light filters down, illuminating the sturdy ribs of the barge, now completely softened by a blanket of plumose anemones. It’s a beautiful contrast, the rough steel against their delicate frills. Keep an eye out for conger eels too; they’ve made these spaces their own. We often spot several tucked away, their heads peering out like grumpy landlords. The site truly shines on a calm, sunny day when visibility extends, letting you appreciate the wreck’s full outline and the life it supports. It’s not a thrill ride, but a serene exploration of a forgotten piece of history, transformed.
