Humm Line Bird Scarer and Deterrent
This item is worth 20 Marine Miles points!
Stretch tightly between two supports and even a gentle breeze will cause Humm Line to vibrate, giving off a sound that birds cannot tolerate and stopping them from fouling decks and cockpits.
Secure the tape to the forestay about 1 metre above the deck and stretch tightly to the shrouds and backstay.
