Pembrokeshire Boat Charters operates from Milford Haven on the south side of the Pembrokeshire coastline, providing specialist marine experiences across inshore waters and the Celtic Deep. The operator's published offerings include full‑day offshore wildlife expeditions, private boat charters to Skomer, Skokholm and Grassholm, diving weekends, snorkelling trips, and a range of fishing experiences targeting species found off the Welsh coast.
Trip types span wildlife watching and photography, sport fishing for porbeagle, blue sharks and bluefin tuna, reef and inshore angling, plus guided dives and snorkelling around seabird colonies and kelp habitats. Each advertised itinerary describes targeted wildlife and typical seasonal opportunities — for example, bluefin tuna trips from August to November and shark sightings in the Celtic Deep. Private charters are described as customizable for families, celebrations and educational groups.
Vessels depart from Milford Haven with skippers experienced in local navigation and sea conditions. Safety briefings, adherence to local wildlife protections, and trip planning that responds to weather and seasonal migration are described as core operational practices. Pembrokeshire Boat Charters is listed on The Adventure Collective as a local specialist offering a range of marine trips, with options that cater to anglers, divers, snorkellers and wildlife enthusiasts seeking day trips and short weekends from Milford Haven.
