The living pulse of your coastline. Marlin turns every marina into a live window on the sea. A network of solar-powered sensor stations measures the real conditions in the harbor and delivers them live, so you always know what the water is doing right now. Six live values, around the clock: water temperature, wave height, wind, water level, air pressure and air temperature. BUILT FOR THE PEOPLE ON THE COAST Sailors: check wind and waves at your marina before you head out. Harbor masters and operators: keep the whole port in view, right from the office. Research and curious minds: explore reliable, continuous coastal data. WHY MARLIN Hyperlocal, not regional. We measure at the exact marina, where general forecasts fall short. Measured, not modeled. Real sensor readings, not distant predictions. Live and continuous. Always current, and always building a long-term record. FEATURES Live sensor map: see real-time conditions across every marina at a glance. Detailed dashboards: dive into the full picture for each station. History and trends: explore past measurements and spot patterns over time. Smart notifications: get push or email alerts the moment a reading crosses your threshold. Open data: transparent access that supports research and innovation across the maritime sector. Born from ocean research in Kiel, Marlin makes the coast readable for everyone who depends on the water. Your coast, live. Download Marlin and see what your marina is doing right now.
