About

Built offshore.
Not in a boardroom.

LYFE Offshore was created by professional sailor and engineer Kalle Coster after years of offshore sailing, racing and living aboard with his family.

Designed from real-world experience — focused on reliable alerts, clarity and trust when it matters most.

Kalle Coster Founder, Sailor & Engineer

"Designed to keep watch so you can sleep, sail or focus on other things."
