Capt's Notebook

The Capt's Notebook tab is the same nautical chart as

SeaTracker, but framed around the marks you have saved.

What changes from SeaTracker

The chart automatically switches to the Captain's Notebook base map

style — a warmer, paper-feel cartography meant for journaling and

planning.

A Pin Carousel appears below the top bar: a row of pill thumbnails,

one per captain's mark you have saved.

Tap a pin to fly the chart to that location.

When you switch away, the chart style reverts to the one set in

Settings → Appearance.

All the chart power is still there — Route and

Voyage sub-modes, every legend layer, the

MOB button, tile caching, and track recording.

Adding marks

There are two ways to start a mark:

Long-press the chart. From any chart mode, long-press the position you

want to save. The captain's mark appears immediately in the Pin Carousel.

Start from a photo. In Capt's Notebook mode, tap the Add Photo button —

the round camera-plus button on the right-hand control rail, just under

Jules. Pick up to four pictures from your library; they become a new mark in

one step. The mark is placed automatically where the first photo was taken

(from the photo's location data) — or, if the photo has no location, at the

centre of the chart. Give it a name, sign it if you like, then tap Add to

Notebook. The chart flies to the new mark and opens it so you can add more.

A mark that has a photo shows on the chart as a round photo pin — a small

circular crop of its cover photo — with its title and date printed just

beneath it, so you can recognise a place at a glance without opening it.

Photos

Open any mark and scroll to Photos to attach pictures from your library.

Each photo is resized and saved on the spot. (You can also start a brand-new

mark straight from photos with Add Photo — see [Adding marks](#adding).)

View — tap any photo to open it full-screen. Pinch or double-tap to

zoom; swipe left/right to move between the mark's photos.

Cover — the first photo becomes the mark's cover, shown as a large header

image at the very top of the mark. Pull the mark sheet down and the cover

stretches. Long-press any photo and choose Set as Cover to change it

(marked with a ★).

Reorder — drag a thumbnail to change the order.

Caption — long-press a photo and choose Caption to add a short note.

Location — if a photo carries GPS data from the camera, a 📍 badge

appears on its thumbnail. In the full-screen view its place name and

coordinates are shown, with a Show on map button that jumps the chart to

where the photo was taken.

Sign your marks

A captain's mark can carry your signature — the digital equivalent of

signing a line in the ship's log. Open a mark, scroll to Captain's Signature,

and tap Sign this mark. The mark is stamped with:

your name (from your captain profile),

your vessel, when one is selected,

the time you signed, and

the position of the mark.

Once signed, the mark shows a seal with those details. You can Re-sign (which

updates the time) or Remove the signature at any time. When you create a mark

from photos with Add Photo, the Sign as Captain switch lets you sign it on

the spot.

Signing needs you to be signed in — the signature uses your captain profile. If

you are signed out, the Sign In button takes you to the

Captain tab.

Using your notebook on passage

The Notebook is the right tab when you are:

Reviewing places you noted on an earlier passage.

Planning the next leg between your own marks.

Sharing a private chart with a co-captain.

If something goes wrong

A new mark does not appear — your mark might be off-screen; check the

Pin Carousel.

The base map looks wrong — switching back from another tab restores your

chosen chart style within a second.

Marks and any photos you attach are saved on the spot and stay put across

app restarts — drop a pin, add a photo, and it will still be there next

time you open the app.
