The Plastimo Standard Trump Fog Horn is a rugged, marine-rated manual foghorn that produces a loud 100+dB blast for reliable sound signalling when visibility closes in around the Irish coast.
It works without gas or batteries—simply blow into the side port to activate the diaphragm—making it a dependable choice for sailing in Ireland where damp, cold conditions can drain aerosols and cells.
The bright yellow body floats if dropped and stows neatly in its tube with a lanyard and two spare membranes, so it’s ready in the grab bag or under the sprayhood.
Compact, economical and eco-friendly, this durable deck equipment suits yachts, RIBs, fishing boats and paddle craft that need a simple, corrosion-proof, always-ready horn.
Sold individually. Supplied with lanyard and two spare membranes in a protective canister.
