More Than Conditions. A Briefing You Can Use.

  • Overall assessment. GO, CAUTION or NO-GO for your boat, measured against the limits you set.
  • Key factors. The conditions that decided it, so you can see what deserves your attention.
  • Best boating window. The hours of the day that sit inside your limits, when there are any.
  • Better alternatives. A later start, an earlier return or another day, when one reads better.

Instead of leaving you to assemble forecasts, observations, tides, currents, timing, and your own limits, GoNoGo WX Boating brings the parts together around the boating you plan to do.

Your Boat Changes What the Conditions Mean.

The same conditions can fit one boat and exceed another boat’s selected limits. GoNoGo WX Boating measures the day against the boat, operating limits, home water, night preferences, and plan entered by the subscriber.

Build an outing and GoNoGo WX Boating evaluates each leg for the time your boat is expected to reach it. See where conditions change, where timing matters, and which part of the route shapes the assessment.

Example passage

Annapolis Harbor to St. Michaels, MD

An example Sunday • Aboard Vista

Departure: 9:00 am · 26.4 nm · 1 h 47 min underway · Arrival: About 10:47 am (allow 10:32 to 11:39 am)

An example day with example conditions, not a forecast.

  1. Leg 1GO

    Annapolis Harbor → Eastern Bay

    9:00 to 10:09 am

    NW 10 kt, seas 1.0 ft

    1 ft following sea, Comfortable cruise speed

    This is the most exposed section, still inside the boat's GO lines.

  2. Leg 2GO

    Eastern Bay → Miles River

    10:09 to 10:26 am

    NW 10 kt, seas 1.0 ft

    1 ft following sea, Comfortable cruise speed

    Conditions ease as you come into protected water: seas under a foot at the far end, 1.0 ft where it starts.

  3. Leg 3GO

    Miles River → St. Michaels, MD

    10:26 to 10:47 am

    NW 10 kt, seas under 1 ft

    Light quartering sea, Little pitching, Minimal spray

    This should be the smoothest section of the trip.

See What Changes When You Leave Later.

Compare departure times, return windows, routes, and days without rebuilding the plan from scratch. When the original plan does not fit, see whether an earlier start, earlier return, different route, or different day does.

Ask About the Plan You Already Built.

Ask plain-English questions about timing, conditions, alternatives, and the parts of the outing worth another look. The Virtual First Mate responds from the briefing and plan already in GoNoGo WX Boating.

See What the Assessment Is Based On.

GoNoGo WX Boating shows the conditions, selected limits, and key factors behind the assessment. When a reading is missing, it stays missing. When forecast sources disagree, the briefing says so.

Built on Far More Than a Forecast.

GoNoGo WX Boating brings together official forecasts and observations, real boating passages, tides and currents, route timing, chart and navigation information, and the limits entered for the boat.

The current engine includes boating passages covering more than 5 million nautical miles, hundreds of government buoys, thousands of tidal-current stations, and official marine and navigation sources.

The miles are recreational boats’ tracks from public AIS records, used when your route matches one.

Sources that require credit

Created by boaters who wanted more than another forecast: a clear explanation of what conditions mean for the boat and outing being planned.

Before You Decide.

What is included?
Everything. Daily email briefings, GO / CAUTION / NO-GO assessments, leg-by-leg cruise planning, the Virtual First Mate, float plans, trip planning, route analysis, local hazard awareness and email alerts on the places you save.

Your trial is the full product, so you can see how it fits the way you boat before you decide. Trial or subscribed, you can ask the Virtual First Mate up to 10 questions a day, and the count resets overnight.

When your trial ends, your boat, limits and saved places are kept, ready the moment you subscribe. Briefings, planning and alerts pause until then, and check-in reminders for a float plan you already sent keep going.
Is a card required?
No. The trial is 7 days, with every feature included and no credit card required. Your first briefing sends the moment you finish setting up your boat. After that it is $149 a year, or $99 for the first year if you subscribe through 11:59 pm Eastern, October 30, 2026. You only enter a card if you decide to subscribe. One free trial per person and boat; we may end a repeat trial and ask you to subscribe.
How do I cancel?
Cancel anytime from your account. Canceling stops future renewals and your access runs to the end of the period you paid for. Your first charge is not refundable, so use the free days to decide. If a later renewal charge takes you by surprise, email support@gonogowx.com within 14 days and we will refund it.
