What is the issue?
If fog descends and you are in or near a busy shipping lane, the first priority is to move out of it as soon as possible and to steer for shallow water where there are no large vessels. But this also brings about the chief danger of land.Why address this?
Sometimes you may not have radar and good charts for this area so you may have to improvise to keep the vessel in safer waters.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?
In fog, you must use the boat's air-horn to indicate your presence to other boats. But few know that you can position the vessel safely offshore using the mandatory airhorn.

If the vessel is under 12 metres and underway, it must give one prolonged foghorn horn blast every two minutes - see getting to grips with sound signals
. You can also use the blast from the airhorn to position yourself using the echo from the sound signal. Listen carefully and time the echo. If the echo takes 5 seconds to travel back to you, you are about half a mile from land, 10 seconds equals about a mile. Cliffs or forested shorelines work best. A flat sandy beach will not reflect the sound as well.
