What is the issue?
When the wind fills and un-fills from the sails in light air it can cause reverberating snapping of shackles. This is particularly the case if the vessels head sail blocks are attached by shackles as was the case with our circumnavigating vessel.Why address this?
The repetitive cracking of the blocks as the wind loads up and drops can be wearisome, particularly so for crew trying to rest.Sail with the Instincts of a Local Pro
Navigation apps only get you from A to B, leaving you guessing about the "where," the "why," and the "how." eOceanic isn't another "nav app." It's the Intelligence Uplift that enhances the tools you already use, powering up both your capabilities and understanding.
Once activated on your device, it doesn't just display data, it brings it to life with real-time situational awareness, giving you a "digital sixth sense" for the coastline.
Go beyond navigation to truly know the coast and everything it offers.
- Sail Stress-Free: Make boat handling easier with a helpful assistant and avoid "hidden" hazards with an extra set of eyes on watch for dangers along the coast.
- Discover More: Most sailors only experience a small fraction of a coastline's rewards. We unlock the "hidden gems" and local resources that create unforgettable experiences for you, your family, and your friends.
- Engage Ashore: We don't stop at the waterline; we bring you in to fully experience the best of the world waiting for you ashore.
The power of knowing. Autonomy, agency, agility and the joy of roaming free.
How to address this?
Dampen the snapping of metal shackle-upon-metal-shackle by placing a sleeve of reinforced PVC hose piping around the 'U' bend of each shackle.

This can easily be accomplished by:
- • Undoing the connecting shackle.
- • Cutting off a section of PVC pipe and heating it by placing it in hot water so that it can be squeezed over the wide eyes at the end of the shackle.
- • Then press the hose cutting around the shackle and reassemble.

Eliminating the metal to metal will have an immediate and dramatic quieting effect.
