I preload Navionics charts and Windy forecasts before we cast off, then switch to airplane mode to save battery and keep GPS alive (https://www.navionics.com, https://www.windy.com). It’s saved me from playing ‘guess the squall’ at 2 a.m., but I still keep a paper chart and a small handheld GPS as backup.

‌⁠‍⁠​‍​‍‌⁠‌​​‍​‍​⁠‍‍​‍​‍‌‍⁠‌‌‍​‌‌⁠​‍‌‍‍‌‌⁠‌​‌‍‍‌‌‍⁠‌‌‍‌‌​‍​‍​‍⁠​​‍​‍‌‍‍⁠​‍​‍​⁠‍‍​‍​‍‌⁠​‍‌‍‌‌‌⁠​​‌‍⁠​‌⁠‍‌​‍​‍​‍⁠​​‍​‍‌‍‍‌‌‍‌​​‍​‍​⁠‍‍​⁠‌‍​⁠‍​​⁠​​​⁠​‍​‍⁠​​‍​‍‌‍‌​​‍​‍​⁠‍‍​‍​‍​⁠​‍​⁠​​​⁠​‍​⁠‌‌​⁠​‌​⁠​​​⁠​‌​⁠​​​‍​‍​‍⁠​​‍​‍‌‍‍​​‍​‍​⁠‍‍​‍​‍‌‍‍⁠‌​​⁠‌‌‌‌‌‍⁠‌‌⁠‌⁠‌‌​‌‌⁠‍​‌​‌⁠‌‌‌​​⁠​⁠‌‍⁠‌‌‌‍‌​⁠​‌​⁠​‌‌‍​‌​⁠​‌​‍​‍‌⁠⁠‌​​

Quick example: I keep a ‘safety route’ GPX preloaded in OpenCPN on a small tablet as a backup and let PredictWind cache GRIBs over marina Wi‑Fi before we leave, so the weather layer stays usable offshore. If you don’t want two apps, Savvy Navvy’s routing+weather is tidy but the subscription isn’t cheap.

And i use OsmAnd+ with OpenSeaMap (https://www.openseamap.org) seamarks as offline backup; cheap, saved me when primary froze.

Coastal runs: I’ve been using Aqua Map with the USACE/NOAA ENC pack and ActiveCaptain notes — download areas, switch to Offline Mode, and the Night palette saves my eyeballs at 2 a.m. One caveat: its internet AIS is patchy offshore, so I cross‑check targets on a small standalone AIS display and only use the app for charting. If you’re curious, here’s the app: https://www.aquamap.app.

On deliveries I run Navionics on a Wi‑Fi‑only iPad paired to a Dual XGPS160 so I can keep the tablet in airplane mode — battery lasts all day and the fix stays steady. Small caveat: don’t park the puck under the sprayhood or multipath will skew your COG, @harborhawk.

Quick tip: before a coastal hop, I open Windy and long‑press each stop to cache the wind/swell layers, then switch my iPad to a red “Color Filters” overlay so apps without true night mode don’t torch my night vision — , those surprise popups. I like iSailor for quick routes, but the tide/current layer is paywalled; as a sanity check I’ll cross‑reference NOAA’s free ENC data when I’ve got signal: https://nauticalcharts.noaa.gov/data/us-enc.html. Anyone else using the accessibility red filter instead of in‑app night themes?

‌⁠‍⁠​‍​‍‌⁠‌​​‍​‍​⁠‍‍​‍​‍‌‍⁠‌‌‍​‌‌⁠​‍‌‍‍‌‌⁠‌​‌‍‍‌‌‍⁠‌‌‍‌‌​‍​‍​‍⁠​​‍​‍‌‍‍⁠​‍​‍​⁠‍‍​‍​‍‌⁠​‍‌‍‌‌‌⁠​​‌‍⁠​‌⁠‍‌​‍​‍​‍⁠​​‍​‍‌‍‍‌‌‍‌​​‍​‍​⁠‍‍​⁠‌‍​⁠‍​​⁠​​​⁠​‍​‍⁠​​‍​‍‌‍‌​​‍​‍​⁠‍‍​‍​‍​⁠​‍​⁠​​​⁠​‍​⁠‌‌​⁠​‌​⁠​​​⁠​‌​⁠‍​​‍​‍​‍⁠​​‍​‍‌‍‍​​‍​‍​⁠‍‍​‍​‍‌‌⁠⁠‌‌​⁠​⁠‌‍‌⁠​​‌​‌​​⁠‍​‌‌‌⁠‌​‍‍‌​‌‌‌⁠‌‌‌‌​​‌‍‍‌​⁠‌​‌‌‌‍‌​‍⁠‌‍​‌​‍​‍‌⁠⁠‌​​

I pipe AIS from a Vesper transponder into iSailor over Wi‑Fi so I still get target overlays when the tablet’s offline, and I flip on ‘Guided Access’ to avoid fat‑finger zooms in a seaway. Small caveat: iSailor’s current arrows sometimes lag after a chart update, so I cross‑check NOAA currents before a tight pass.
