Telltale Sailing

Telltale is sailing intelligence for cruising and racing boats: a coastal wind forecast that knows the land, weather routing built for your boat, and a logbook that writes itself. WIND THAT KNOWS THE COASTLINE Global models smooth over islands, headlands and valleys. Telltale Coastal Wind (TCW) adds the effect of the coastline and terrain to the regional forecast, so you see the acceleration round the cape and the shadow behind the island before you sail into them. • Compare forecast sources side by side, at the same place and time • Wind, gusts, pressure, rain and swell along the route and at the anchorage • Every briefing shows its source, its age and how sure it is • Telltale Inland Weather for 91 lakes across Europe, the US and Canada: lake breezes, valley winds and cold-air pooling • Best (auto) picks the strongest model for each place, from Météo-France AROME to Canada's HRDPS ANCHORAGE SHELTER AND COMFORT — NEW Know how the night will feel before you drop the hook. Telltale runs a high-resolution physics model of the bay: the swell is carried in on a 30-metre grid over surveyed seabed and terrain — bending round headlands, spreading into the lee, shadowed by the land and reflected off steep shores — while Telltale Coastal Wind and the tidal stream decide which way your boat will lie. • Hour by hour: how she swings, how big the waves at the anchor are, and the angle they meet her bow • Judged against your boat's own roll period and windage, and against what you call comfortable • Animated on your own chart, from the Anchorage page WEATHER ROUTING FOR YOUR BOAT • Isochrone routing with your boat's ORC or estimated polars, over land and depth • Departure sweep: route the same passage from several start times and see that the fastest is not always the most comfortable • At the helm: favoured tack, target angle and distance to the layline when the mark is upwind • Import and export routes as GPX A LOGBOOK THAT WRITES ITSELF The passage records itself: track, distance, duration, and regular log entries without anyone having to remember. THE WHOLE BOAT IN ONE PLACE • Maintenance tasks, projects and equipment • Insurance, registration and manuals kept aboard • Energy budget: consumption, solar yield and battery outlook for passage and anchorage • Share the boat with your crew CONNECTS TO YOUR INSTRUMENTS Telltale works on the phone's own GPS. Connect a NMEA 2000 WiFi gateway and it reads position, speed, heading, wind and depth straight from the boat. Add a Telltale Bosun, a small computer that stays aboard (optional, sold separately), for continuous logging and anchor watch while your phone is ashore. WHAT TELLTALE IS NOT Telltale is for planning and decisions, not live navigation. It is not a chart plotter or a collision-avoidance system, and it does not replace your plotter, paper charts or seamanship. Fresh forecasts and routing need an internet connection. Some features require a Telltale subscription. For iPhone and iPad. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
