This traditional call is not just a whistle, but a musical instrument that can change pitch. Historically, the boatswain's pipe was used to pass commands to the crew when a human voice could not be heard over the roar of the sea. The versatility of this whistle allows for communication in noisy conditions on land as well.

Made in England by ACME Whistles, the iconic manufacturer who created the world's fist police whistle back in 1883. This nickel-plated Boatswain Pipe comes with full instructions and charts for producing the many official calls used by navies across the seven seas.
