RFA Jersey Queen

Categories:

The Jersey Queen was requisitioned by the admiralty as a stores carrier. It hit a mine 06/10/1940 and sank in 56m of water.

Holland Rock

Categories: Tags: , ,

A small pinnacle on the outer edge of the Whelps. So called due to a group of Dutch divers visiting the site many times over several years, it was one of their favourite dives. Covered in life, competing with some of the best reefs around Cornwall.

It is slowly becoming a favourite of the locals that have dived it.

Lath Rock

Categories: Tags: , ,

Lath Rock is situated close to the centre of Veryan Bay. It is a pinnacle reef system that slopes down from around 7m down to 26m, even deeper as it slopes off more gently.

Covered in a range of marine life, it is a very scenic dive. Worthy of several visits, to explore it properly.

H.M.S. Primrose

Categories: Tags: , ,

The HMS Primrose was a sailing gunship that hit the Manacles in 1809. Over the years it has been subject to various types of salvage, many times. What remains now are just a few cannon balls and some encrusted items. Every now and then something new is found but nothing of any great significance for a long time.

At the church in St Keverne there is a carronade, removed from the HMS Primrose, it is visible from the road in front of the church.

Wessex Archaeology recently surveyed the Primrose, trying to work out if it was worth protecting, along with our help. They decided there wasn’t enough left to designate it as a protected site.

City of Ghent wreck

Categories: Tags: ,

The City of Ghent was a 616 ton, 64m long motor vessel. It hit Black Head but managed to get off, it was taking in water and started to list, then sank near the Lizard point on 15/11/1953.

It now lies upside down and although the superstructure has collapsed, it is reasonably intact. An excellent dive where tide timings are important. Maximum depth is around 35m.

Pen Wyn Reef

Categories: Tags: , , , , ,

Pen Wyn is one of many pinnacles on the Manacles Reef, sitting next to Vase Rock. The top of the rock is around 6m, with the sea bed as far away as 44m. Covered in anemones and corals, it is often described as an underwater garden. One of the U.K’s best reefs. It is so close to Vase rock that one dive could encompass both sites.

Half Way Rocks

Categories: Tags: , , , , ,

Half way rocks is so called because it is part way between Vase Rock and Maen Voes. It is the most dramatic of all the pinnacles on the Manacles with one side being almost vertical, from 12m to 37m. It is quite often confused with PenWyn although it is around 50m away. The top of the rock is around 12m, with the sea bed as far away as 37m. Covered in anemones and corals, it is also often described as an underwater garden. One of the U.K’s best reefs. read more →

Gull Rock Caves

Categories: Tags: , , ,

Lying between Gerrans Bay and Veryan Bay, Gull Rock stands high just 600m from shore. On the south side is a much smaller rock, the Gull Rock Calf. read more →

Outer Bizzies Canyon

Categories: Tags: , ,

The Outer Bizzies Canyon is an 8m wide gully with 13m Pinnacles (LW) on each side. It is a part of the Bizzies reef system. It needs to be dived at slack water to get the most out of the dive. The dive usually starts at around 26m, at the base of the pinnacle, at the bottom of the canyon. There are some tall vertical walls covered in colourful anemones and soft and hard corals, as you make you way up the the top at around 13m (low water).
