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, Joran — 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 13 lakes — one tap away. 13 SWISS LAKES Zürichsee · Lac Léman · Bodensee · Vierwaldstättersee · Thunersee · Brienzersee · Lago Maggiore · Lago di Lugano · Neuenburgersee · Zugersee · Walensee · Bielersee · Murtensee OFFLINE MAPS Download your lake once.
