Diving for all levels

Portland Boat Diving

Portland has long been a divers paradise for boat diving to local as well as deeper Channel wrecks, drifts and reefs. The island’s dive boat fleet operates out of two locations: Portland Marina and Castletown, each only minutes away from Underwater Explorers.

Portland dive operators offer daily shuttles to popular dive sites for individuals and buddy pairs as well as day charters where you can book the whole boat for a day or more. Depths of sites visited from Portland address all levels of experience ranging from 10 to 60+ metres. There are a vast amount of wrecks easily accessible from Portland as well as some wonderful underwater nature trails and drift dives. Portland harbour itself allows for sheltered diving in almost all conditions but for serious storms.

Daily in-and-out trips to a multitude of dive sites both in and outside of Portland Harbour are offered by hard boat operators at the Marina and RIB operators in Castletown. On a shuttle day boats may go out up to 4 times, bringing you back to shore in between dives. You can book for all or any of the dives going out – or just do one dive if you like. Fees are paid per person on a per-trip basis directly to boat operators (we have no affiliation) and generally depend on the distance of dive site to Portland. Portland dive shuttles are ideal for individuals, small groups and schools whether you are diving weekends or week days.


Portland Marina

Check out hard boat (Skindeep/Skindeeper & Scimitar) shuttle dates and availability at Portland Dive Charters and/or Scimitar Bookings. Minimum numbers tend to vary by season, day of the week and advanced bookings. However, most hard boats will commit to go out with a minimum of 6 passengers and sometimes even 4 if conditions are favourable mid week, so it’s always worth contacting the skippers directly.

If you are a club and can’t make up the numbers to charter a boat, skippers may take smaller group bookings and advertise the trip to get more divers on board.

For Scimitar contact Nick (Scimitar Diving) and for Skindeep/Skindeeper contact Ian or Oona (Portland Dive Charters).

Castletown Jetty

For weekend or week day daily RIB diving shuttles visit Dive Beyond who runs two powerful RIBS from Castletown, Portland (just down the road and right on the seaside with their own jetty). Dive Beyond is also Portland’s only PADI 5 Star IDC (centre). They can often also cater for buddy pairs, single divers who require buddies and welcome divers who are doing their first UK or boat dives.

When you come back from a dive, or in between shuttles, both the Marina and Castletown offer various facilities ranging from toilets to on-site cafe, showers and rinsing stations. And don’t forget, we’re only a minute distance from both sites and great place to drop in whether you want to browse, shop, rent kit or just get fills. Both the Marina and Castletown also offer fills.
