Updates

What I shipped, newest first.

October 23, 2026

I redesigned the site, and I added the tide charts.

This is the October log. The homepage, harbor pages, tide charts, and water temperature are live. The call itself did not change. Boat, Caution, or Nope still comes from your limits and the same buoys.

New look

The homepage, the regions list, and each harbor page have a new layout, with the flag up top.
On a phone, the menu is All harbors, Marine forecasts, Guides, My boating, and Sign in.
Every public page ends in the same footer.
If you have not saved a home harbor, the homepage starts from the coast you are on, and falls back to Cape Cod. A harbor you saved as home still leads.
The iPhone page shows the real App Store screens.

Harbor pages

The flag word fits the cloth. Caution no longer runs into the pole or off the edge. The homepage flag does the same for Caution.
An advisory, such as a Small Craft Advisory, hangs on the flag. Open it for the alert.
Best window lines up under the flag. If the day never gets comfortable, it says "No good window today."
The day chart uses a solid line for what was already observed and a dashed line for the forecast, with a mark for now.
The tide table is one row per day: highs and lows together, today marked, sunrise and sunset. No moon column.
Tide and water pages link back to that harbor's Boat or Nope call.
Favorite and home sit next to the harbor name.
While the report is still coming in, the flag says "Checking the water…"
The homepage flag now gives a call for harbors outside the Northeast, instead of staying on a question mark.
A dictated boat name shows with normal capitalization. "a 31 ft chris craft launch gt" reads "31 ft Chris Craft Launch GT."

Tides and water temperature

Tide charts for 2,628 NOAA stations, in 29 states.
Water temperature for 609 NOAA stations, in 35 states.
Each station has its own page. The chart, or the latest reading, comes first. Nearby stations are lower on the page.
On the state lists, the line under a name is the station number, or the town when that town is different from the name. The name is not repeated.
A harbor page links to the tide station and the water station it uses. A state page links to that state's charts and water temperature when they exist.
Tide charts and water temperature are both in the footer.

Faster pages

Pages load faster. You can read the homepage before the extra scripts show up.

Fixes

The desktop header no longer adds a button that only repeats the page you are already on.
The homepage and Regions count the same harbors: 8,559.

Earlier

August 13, 2026A clearer view of the whole boat day.

Location pages now make it easier to scan current conditions, compare the week ahead, and follow wind, waves, wind direction, and tides from midnight through 11:59 PM. We also made forecasts and nearby observations easier to tell apart.

August 13, 2026A clearer full-day forecast is coming to iPhone.

Version 1.3 brings the redesigned Location Detail view, smoother full-day charts, hourly wind direction, easier time scrubbing, a clearer week-ahead view, and a persistent knots-or-mph setting. We’ll update this note when it reaches the App Store.

August 5, 2026Boat or Nope is live.

Last week we launched Boat or Nope on the web and iPhone: one place to bring wind, waves, tides, weather, observations, and advisories together around the limits that fit your boat. That was the starting line, not the finish.
