Know what kind of day it is for your boat.

Plan your time on the water.

Wind, hour by hour

Thomas Point, MD · scored against Vista, an example boat

Holds to about 1p

18 kt12 kt57a79a1011a141p183p235p177p

Plan to be back in port by 1p.

Wind holds to about 1p, then it goes to caution. That is the wind alone. The briefing scores seas, rain, storms and your own water against your numbers too.

Now read your own water.

Those are a preset's limits, not yours yet. Set your own and every morning arrives scored against them.

A two-hour sunset cruise, lunch across the bay, or a major passage. We read the day against your boat and tell you what matters and why.

10 days, no card, about a minute to set up.

What does somebody ashore need?

  • When you are expected back.
  • A check-in before the hour passes.
  • A float plan, and who to call.

What it actually says

The call, and the reason under it.

Today · Vista, an example boat · 12 kt and 2 ft limits

CAUTIONon the day you have planned

Thunderstorms drive today’s call, from about two o’clock.

Wind and seas stay inside Vista’s limits all day. They are not what closes this out.

What would change this

A morning departure. The storm risk sits after midday, and the water before it is comfortably inside your numbers.

An example day, on an example boat. Yours reads your own water, against the limits you set.

And the kind of thing it tells you about a run: “the window stops at the light rather than at the weather.”

What actually lands in your inbox

One document. The same comprehensive briefing every day.

A minute at the dock tells you the call. Everything under it is there for the days you want the detail.

A good day for VISTA

Your boat, by name

The call is made against VISTA’s numbers, not against a generic small craft. A 19-foot center console on the same water gets a different answer.

North wind holds under 14 kt through the morning and the bay stays comfortable for her. It builds past your 15 kt line around 2p and the chop follows about an hour later, so an early start and an early finish is what this one asks for.

Custom, not canned

It opens on whichever factor came closest to your line, so the first sentence is never boilerplate. Today that is the wind. Tomorrow it might be the seas, or the fog.

On the water now · Thomas Point, 4.1 nm

The same readings in the same order, wet or dry: when one is missing it says which and why. An example boat on an example morning. The rest of the briefing is the hours ahead, the week ranked, the water, the sky, and how the call was reached.

Going somewhere, not just out

A briefing on every leg, at the hour you are on it.

A run is not one piece of water. It is a different one every hour.

  • The roughest stretch, and when you would be on it.
  • The latest you can leave and still be in before dark.
  • Where you can get in, if it turns.
  • The stretches where wind over tide makes it steeper than the height suggests.
  • What would change the answer.

Then a float plan for whoever is expecting you.

An example passage

Annapolis to Rock Hall, Saturday, aboard Vista

22.1 nm · away at 8:00a · alongside about 10:20a

  1. AnnapolisBay Bridge8:00a to 8:40a

    9 kt from the north, seas under a foot.

    Wind on the bow, and light enough that it does not matter.

    The stream turns at 8:52a, from ebb to flood.

    6.8 nm · heading 348° · 10.1 kt over ground

  2. Bay BridgeSwan Point8:40a to 9:55a

    Building to 15 kt, seas 2 ft with the odd 3.

    Wind forward of the beam for this whole stretch.

    A knot and a half of foul current under an opposing breeze.

    Wind against tide from about 9:20a. Expect it steeper and closer together than the height suggests.

    11.4 nm · heading 012° · 8.9 kt over ground

  3. Swan PointRock Hall9:55a to 10:20a

    Back inside 10 kt once you are behind the point.

    Wind astern, and the fetch runs out.

    3.9 nm · heading 067° · 9.4 kt over ground

Move the departure an hour and every one of those lines moves with it, because each leg is read at the hour your boat is actually on it.

Tell it what you are doing. That is the whole setup.

Around here

A departure and a return window. No destination, because there is not one.

Out and back

Where you are headed, how long you want there, and when you want to be in.

Going somewhere

The run end to end, read leg by leg at the hour you are on each one.

Or write it the way you would say it out loud, and check what we read back before anything is built.

What you get

Set it up once.
It runs every day after that, at the time you choose.

Your GoNoGo WX marine conditions briefing. Nothing to open, nothing to remember, nothing to check.

01

Everybody ashore and aboard.

Going out for the afternoon, share when you are expected back. Going somewhere, hand over the whole float plan: the boat, who is aboard, the route, the check-ins, the arrival, what safety gear is on board, and what to do if you are overdue. Send the morning's briefing to as many as 3 of your crew.

02

A captain to ask.

Put your plan in front of it and ask what you like, in plain words. It answers from the same live readings, about your water and nothing else.

03

The readings, reconciled.

Official forecasts and live stations do not always agree. It reads them together, tells you how sure the day is, and says so by name when one goes quiet.

Change the plan without starting over.

  • What if we leave two hours later?
  • Can we be home before dark?
  • Which leg is roughest?
  • Where can we get in?
  • Is tomorrow better?

It answers from the readings already on your plan, and it will tell you when the briefing does not say.

Every briefing draws on multiple sources and hundreds of data points: NOAA forecasts, National Weather Service marine warnings, and the government buoys nearest your water, combined into one comprehensive briefing for your boat.

What every part of a briefing means

Why this exists

Built by experienced boaters who were tired of piecing together current and predicted boating conditions from a dozen places, and still not knowing what the day meant for their own boat.

Wind from one source, seas from another, storms in a third, and none of them scored against the vessel you actually keep or the limits you actually run. Whether it is a short day cruise or a passage, the question is the same: is today inside your limits, and when does that change. So the numbers here are always read against a boat, and the call is always left with the captain.

It gives you the answer. You keep the wheel.

Leave the dock already knowing.

Pick your boat, set your home port, and the briefing is on screen before you are asked for anything else. It tells you where the day sits against your own numbers and the hour that changes. You know your boat, so the call stays yours.

$65 a year at the founding rate, $89 after. One briefing every morning of the season, and passage planning whenever you are going somewhere.

10 days of the whole product first. No card.
