POS

POS is an advanced dive site in the British Virgin Islands — a site whose abbreviated name carries local diving significance within the BVI dive community, referring to a specific underwater feature or location in the island group that requires advanced skills and planning to dive safely. The advanced rating suggests depth, current, or structural complexity that demands experience beyond open-water certification level. The BVI's Sir Francis Drake Channel and the surrounding island waters are subject to significant tidal current movement, particularly around exposed headlands, points, and channel passages, and many of the BVI's most exciting dives are current-driven experiences where timing and current management are critical elements of the plan. At advanced sites in the BVI, experienced divers are rewarded with encounters with Caribbean reef sharks, large pelagic species, and the dramatic open-ocean character of sites that receive the full influence of the Atlantic through the Drake Channel. Schools of horse-eye jacks and large barracuda are characteristic of current-swept BVI sites. Spotted eagle rays cruise the deeper margins with effortless grace. The reef fish diversity of the BVI is impressive — decades of marine protection and the archipelago's position at the intersection of Caribbean current systems have produced a fish community that represents the full range of Caribbean reef species. Advanced divers visiting the BVI will find that the current-swept sites like POS offer a dramatically different and more adrenaline-charged version of Caribbean reef diving than the calmer, more sheltered beginner sites — one that showcases the power and productivity of the Caribbean's oceanic circulation at its most visceral.
