Plymouth is a naval port city located on the south coast of Devon, about 190 miles (310 km) west-south-west of London. It lies between the mouths of the rivers Plym to the east and Tamar to the west. Where they join is Plymouth Sound, widely regarded as one of the world’s most impressive natural harbours.

Our relationship with Plymouth began in the late 1970’s when Sonardyne’s founder, John Partridge, chose the area to begin testing at sea some of our earliest products. Over four decades later, Plymouth remains integral to our technology research and product development programmes.

The area’s appeal lies in the diversity of water bodies, water depths, harbours and natural inlets that are on offer within a short transit from one of the city’s many marinas. This maximises the time available to evaluate marine equipment following arrival at a test site.

Our Plymouth base of operations is Pier House, located in Turnchapel. Pier House comprises office and training space, mechanical workshop, electronics laboratory as well as accommodation in the form of Pier Cottage. The building also has its own slipway and pier. Our vessel fleet is conveniently based in Mayflower Marina which offers full tide access providing you with the flexibility you need whatever the time of day or year. The marina is located within five minutes drive of Plymouth City Centre and offers secure parking, restaurants, bars and cafes.

We regularly conduct vessel operations around Plymouth Sound which has three approaches. The marine entrance is from the English Channel to the south, with a deep-water channel to the west of the Plymouth Breakwater. There are two freshwater inlets: one, from the northwest, is from the River Tamar via the Devonport Dockyard, the largest naval dockyard in western Europe. The other, is from the River Plym in the northeast, which empties into Cattewater harbour between Mount Batten and the Royal Citadel.

So whether you are looking for deep water, brackish water or shallow water, Plymouth and the surrounding region offers it all. To discuss your requirements, get in touch today.
