Key Dive Site Facts
Dive Site Overview
Churchill Barrier 3 is a historical site where wartime blockships were scuttled to defend Scapa Flow during both World War I and World War II. These intentionally sunken vessels now form artificial reefs and accessible dive attractions.
Divers can explore the SS Reginald, often visible from the barrier itself, which lies broken in two. SS Empire Seaman, a single screw steel steamer, offers numerous swim-throughs and points of interest, remaining relatively intact.
Nearby, SS Martis is in similar condition, supporting a range of sea life, while SS Gartshore, a WWI blockship, is more broken up, though its propeller, rudder, and prop shaft are still distinguishable. Another wreck, Lapland, is totally collapsed and sits directly beneath the concrete causeway.
Reaching a maximum depth of 12 m (40 ft) at high tide, it's a shallow site suitable for a broad range of certified divers.
Best Time to Dive
Maximizing your dive experience at Churchill Barrier 3 typically aligns with the warmer, calmer months. May, July, and August generally offer 'Good' dive scores, influenced by more stable conditions. During these periods, average air temperatures range from 10.2°C (50.4°F) in May to 13.9°C (57.0°F) in August, creating a more comfortable surface environment. Rainfall is also comparatively lower, with July averaging 2.67 mm and May 1.77 mm, reducing potential run-off and improving clarity. While the barriers provide shelter, lower wave heights, particularly from May through August (ranging from 0.76 m to 0.98 m), contribute to easier entry and better underwater visibility, making planning during these months advisable.

Dive Experience & Conditions
Accessing Churchill Barrier 3 for shore diving is straightforward from either the north or south shore. For SS Reginald, entry is typically easy from the south shore; divers simply walk into the water and head north. Divers targeting SS Empire Seaman, SS Martis, and SS Gartshore can enter from the north shore using a similar walk-in method. Almost immediately upon entry on the north side, the propeller, rudder, and prop shaft of SS Gartshore become visible. Seabed drops off suddenly after entry, reaching a maximum depth of 15 m (50 ft) in certain areas. Churchill Barriers themselves provide considerable shelter from wind and swell, contributing to manageable conditions even when weather is less favorable elsewhere. This makes the site a pragmatic choice for many weather scenarios.
Dive Difficulty & Safety Guidelines
Understanding the specific requirements and potential hazards at Churchill Barrier 3 is crucial for a safe dive. Diving here is suggested for novice divers when accompanied by an instructor, highlighting the importance of guided experiences for those new to wreck diving or cold water environments. A key hazard to be aware of are weever fish, which can sting if accidentally stood upon without appropriate foot protection like boots or fins. Divers should not attempt to enter or climb onto the wrecks or the Churchill Barriers themselves. Near the north end of Barrier 3, specifically on the east side, a steep drop exists at the carpark, with an abrupt drop-off of the seabed shortly after entering the water; divers should be mindful during entry and exit.
