Frequently Asked Questions

A briefing for your boat, read against the limits you set: every morning, and for any trip you plan, leg by leg. GoNoGo WX Boating comes with a Virtual First Mate to answer your questions and a float plan for whoever stays ashore.

GoNoGo WX Boating gathers every condition it can find for your water and synthesizes them against your boat and the limits you set into one briefing: GO, CAUTION or NO-GO, the key factors and the best hours to be out. Every morning, and for every trip you plan.

You set the limits that would change your day: sustained wind, sea height, visibility, and the chance of rain you will run in, plus, under Advanced, wave period, water temperature, and how far ahead a storm counts. Gusts count against your wind lines too. Every briefing and plan is read against those numbers.

Each limit has a GO line and a NO-GO line you set. GO is inside your GO lines, CAUTION is past a GO line or under an advisory, and NO-GO is past a NO-GO line, under a marine warning, with thunderstorms close, or when conditions past your GO lines add up, such as a Small Craft Advisory with wind or seas past your GO line. How It Works →

A minute at the dock tells you where your day stands: GO, CAUTION or NO-GO, the key factors behind it and the best hours to be out. Everything under it is there for the days you want the detail: wind and seas, storms, tides, currents, advisories, a seven-day outlook, and the options worth considering. See an Example Briefing →

Yes. GoNoGo WX Boating splits the trip into legs and reads each leg at the hour you would be on it, against your limits, from a two-hour run to a long passage. Move the departure and every leg is read again, so you see which window is calmer and what waiting buys you.

Your Virtual First Mate answers plain-English questions from your briefing and your plan: Would leaving later help? Which leg looks roughest? Can we make it back before dark?

Who is aboard, the route, the departure and destination, the check-ins, the expected arrival, the safety gear and the hour to treat you as overdue: what the Coast Guard form asks a shore contact to hold. It goes to your shore contact in one tap.

US waters: the Atlantic, Gulf and Pacific coasts and the bays, sounds and rivers behind them, the Great Lakes, inland lakes, Hawaii, Alaska, Puerto Rico and the USVI. Your limits apply the same way everywhere. What we can read varies by water, and the briefing says so. Every coast and the Great Lakes get buoys and the Weather Service's marine forecast. Salt water gets tide predictions, and most of it tidal currents. Inland lakes get the wind and weather forecast. Local hazard notes, like crab pots, shoals and bars, are most detailed on the Chesapeake and Delaware Bay.

Readings come from official US government sources and independent weather models, and place names from open map data. Every briefing combines official forecasts, buoy and station readings, tides, currents and advisories, measured against the limits you set. The sources whose licenses require credit are on Data Sources. Data Sources →
