A mobile-first PWA for real-time sailing and current conditions in Oyster Bay / Long Island Sound — designed to check while walking to the dock.
Real-time sailing conditions: wind, barometric pressure, weather, and forecast.
Consecutive hourly surface current forecast images for Long Island Sound from Stevens NYHOPS.
Note: NYHOPS LIS coverage and frame numbers are pending verification.
Interactive Leaflet map with OSM + OpenSeaMap nautical chart and NYHOPS current forecast overlay.
Note: bounding box and buoy markers are placeholders pending LIS verification.
