GO / CAUTION / NO-GO Assessments
Conditions are measured against the limits you set, and every call includes the reasons behind it.
GOCAUTIONNO-GO
- GO.
- Conditions are within the limits and preferences you selected.
- CAUTION.
- One or more conditions deserve closer attention before departure or while your plan is underway.
- NO-GO.
- One or more conditions exceed a limit or trigger a setting you selected.
What Comes With Every Call
- The factor driving the call
- How that factor compares with your limit
- What otherwise looks favorable
- What could change the assessment
- The timing of important changes
- Conditions expected at arrival, not only at departure
See all included features ↓Show fewer ↑
Additional Context
- Model agreement when it is relevant to your limit
- Data freshness and availability
- Trends since the previous assessment
- The duration of a favorable or unfavorable window
- Factors that are shown for awareness but do not determine the call
The call is personalized and explained. The decision always remains with the captain.
The call, and the briefing it comes in
Today · Vista, an example boat · 12 kt and 2 ft limits
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.
Thursday, August 20 · Annapolis, MD
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.

Afternoon

Evening
GO
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
7 kt from the north, seas 0.7 ft, water 76°F, reported 12 minutes ago.
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.
Cruise Planning
Trip Planning
A local afternoon outing and a longer passage begin with the same questions: where are you going, when will you be there, and what is expected along the way?
What You Can Plan
- A local outing without a separate destination
- An out-and-back day trip
- A point-to-point cruise
- A multi-leg passage
- The return trip on its own timing window
- Trips using saved destinations and locations
See all included features ↓Show fewer ↑
Planning Capabilities
- Departure-time comparisons
- Arrival-condition assessments
- Cruise-speed-based ETAs
- Arrival windows
- Plain-language trip entry
- A seven-day outlook on any saved location
Describe the trip in the way you would say it, then review the route, timing, and conditions before departure.
Leg-by-Leg Cruise Conditions
A cruise is not one unchanging stretch of water. Each leg is evaluated for the hour you are expected to be on it.
On Every Leg
- Conditions expected along that stretch
- Wind relative to the boat's course
- Sea direction relative to the course
- Current expected at the time of passage
- Wind against current where the combination matters
- The roughest stretch and when you are expected to reach it
See all included features ↓Show fewer ↑
Timing and Alternatives
- ETAs based on your boat's cruise speed
- Arrival windows that reflect trip length
- Best departure windows
- The latest practical departure before your selected return time
- Alternate timing compared side by side
- Recalculated conditions when departure changes
See what is expected beyond the departure point and throughout the cruise.

An example passage
Annapolis to Rock Hall, Saturday, aboard Vista
22.1 nm · away at 8:00a · alongside about 10:20a
- Annapolis → Bay 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
- Bay Bridge → Swan 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
- Swan Point → Rock 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.

What-If Planning
When you change the departure time or another planning detail, the Virtual First Mate can recalculate the relevant legs, timing, gates, and arrival conditions and show what changed.
The Virtual First Mate works from the same conditions and planning information used by GoNoGo WX. It supports the captain without taking the captain’s place.

Understanding the Day
Conditions Read Together
No boating condition exists in isolation.
GoNoGo WX evaluates wind, waves, visibility, storms, tides, currents, advisories, local hazards, timing, and route conditions together, then measures the complete picture against the limits you set.
The result is one personalized briefing with a clear call and the reasons behind it.
What Is Evaluated
- Wind, gusts, and direction
- Wave height, period, and direction
- Wind and sea angle relative to course
- Visibility
- Thunderstorms and lightning
- Precipitation
See all included features ↓Show fewer ↑
Additional Conditions and Context
- Water and air temperature
- Barometric pressure and trend
- Marine advisories and warnings
- Tides and tidal currents
- Storm timing
- Local hazards
- Route and arrival conditions
- Day-to-day trends
- Data freshness and availability
- Agreement among available condition models
Some conditions are included for awareness without determining the GO / CAUTION / NO-GO call. When information is unavailable or no longer current, GoNoGo WX shows the gap rather than filling it with an unsupported assumption.

Visual tools turn detailed conditions into clear, quickly understood views of the day and the cruise ahead.
