LacNav - Swiss Lake Navigation

Navigate Swiss lakes like a local.

LacNav knows every shore zone, every speed restriction, and every named wind — so you can focus on the water, not the rules. Built exclusively for Swiss waters. Not adapted from an ocean app.

SHORE ZONES & SPEED ALERTS

Real-time audible alerts before you enter a restricted zone or exceed the speed limit. Stay legal without watching the screen.

LAKE CONDITIONS AT A GLANCE

Live wind, gusts, water temperature, wave height, UV index and lightning alerts — everything a skipper needs before leaving the dock.

WIND, RAIN & CURRENT OVERLAYS

See the Bise building on the Zürichsee before you cast off. Named winds — Bise, Foehn, Séchard, Tramontane — identified and displayed directly on your chart.

DYNAMIC SPORT SPOTS

Stop guessing. LacNav reads live conditions and tells you exactly where and when the water is perfect for wakesurf and sailing.

FUEL, MARINA, RESTAURANT. ALL ON THE MAP.

Every fuel station, marina, boat ramp, ferry terminal, restaurant and public facility on all 8 lakes — one tap away.
