The Shakewell valve, to say Shakewell seacock, is a thru-hull valve. Seacocks are the most critical components in a boat.

Their reliability can mean the difference between life and death.

When the 81’ MARTELA lost her keel and capsized off Punta del Este, she remained afloat for 5 weeks thanks to the air entrapment maintained by Shakewell Seacocks.

The importance of seacocks is not diminished by less dramatic circumstances: engines, toilets and cockpit drains can all be rendered useless by malfunctioning valves. The weekend sailor is as dependant upon them as the round-the-world racing skipper.

Shakewell is one of the first marine grade composite thru-hull flush fittings. These modern marine non metallic valves has superceded old heavy bronze fittings.
