See who is out
Share your position and heading, or your track for the last 1, 4, 12, 24, 72 or 120 hours, with friends, a boat or a group. Boats draw as pucks with a heading vector as long as their speed. A captain can shut a share off for the trip.
41°51′N 070°18′W · One bay · Commercial crews only · Closed beta
Know where the fish are before you burn the fuel.
Cape Cod Bay and nowhere else, for the boats that fish it for a living. Striped bass and bluefin are what most of the fleet is chasing, and the same ten seconds logs the other 61 species you land besides.
Coverage
Cape Cod Bay, the canal to Race Point. One chart, one fleet.
Species
Bass and bluefin on their own buttons. 61 more in the picker.
Who is on it
Commercial crews, by invitation. Your boat, your groups, your friends.

We’ll email you to confirm, then review.
Tripled Up only works if the boats around you are on it. Invite up to four — we’ll email them and put them in the same queue.
Everyone confirms their own email before anything happens. Leave a row blank to skip it.
One trip, start to finish
An open commercial day in June, dock to dock.
Nothing here needs you to stop what you are doing for more than a few seconds.

Start the trip once
The phone records the boat’s track in your pocket, screen off, and stops on its own when you tie up. It only records on the water, so a trip you forgot to end never records the drive home.

File it in ten seconds
Sighting, bite, catch or conditions. Pick the fish, pick who sees it, post. Air and sea temperature, depth, wind, current and wave height are read from where you are and attached for you. On iPhone you can skip the phone altogether: “Hey Siri, log a bluefin with Tripled Up.”

Look at the chart, not the sky
Your track, your crew’s tracks and every report you are allowed to see, drawn on the real NOAA vector chart — depth areas, contours, soundings, buoys, lights, wrecks and obstructions. It is cached on the phone, so it draws with no bars and no signal. The heat map shows where the reporting is actually happening.
16:50Back on the hard
Fill in what you were too busy to log
Tap any point on your own track — this trip or one from last season — and file the report there, at the time you were actually there. The log book holds every trip and every fish, with a CSV you can download for your own records.
On the boat
What it looks like at six in the morning.
Real screens, real Cape Cod Bay, real fish. The crew names and positions are a test fleet, so nobody’s numbers are on show.
Everything you are cleared to see, newest first. Species, method and style on every card, and the exact position when you are allowed it.
Four taps from pocket to posted. Air and sea temperature, depth, wind and position attach themselves.
NOAA soundings and contours, your own track, the reports on it, and the boats that shared theirs.
Points for verified catches. By day or week, by species, for a person or a whole boat.
The rest of it
Built for one bay and the boats that work it.
No feed to grow, no strangers to impress. Everything here assumes you are working.

Alerts
A nudge worth reading
A push when reporting picks up near you, when someone notices your post, and the evening before every open commercial striped bass day, straight off the Massachusetts season calendar.
Messages
Straight to the boat
Direct, boat-wide or group messages, with a photo or a pinned position attached. Delivery state on every one, so you know it landed.
Crews
Boats and groups
Rosters with captains and co-captains. Post as yourself or on behalf of the boat, and keep crew intel on a channel that stays with the crew.
Top 100
A leaderboard that holds up
Catches earn points. Photos on catch reports are checked for the species you declared, for originality, and against photos already submitted. Every call to remove a report or take back points is made by a person.
Offline
Works out of range
File a report with no bars and it queues, then syncs when you come back in. The app launches offline and the chart still draws.
Who sees what
Your numbers are the whole business. You pick, every single report.
What a friend sees
The track, the report, and the number off the plotter.
What everyone sees
A circle roughly a nautical mile across. No track, no number.
Only me
Goes in your log book and nowhere else.
Friends
People you accepted. They see the exact spot.
A group
One boat or one group. Same, inside those walls.
Everyone
Offset up to about a nautical mile before anyone sees it. Nobody gets your exact number.
Finding friends from your contacts hashes every number on your phone before anything is sent, so we never receive a contact’s number. Tracks follow the same rules as reports, and only record on the water. You can delete your account and everything in it yourself, from the app or from the web, without asking anyone.
Read the privacy policy →Everything you land
Bass and bluefin lead it. Sixty-one more are already in the picker.
Sightings, bites, catches and conditions, for anything landed commercially in Massachusetts. Species whose commercial harvest is prohibited are deliberately left out, because a log book should not invite you to record a violation.
Top-level choiceStriped bass
Its own button, because it is what most of this bay is doing. Open commercial days come off the season calendar, and you get a reminder the evening before one.
Top-level choiceBluefin tuna
The other one-tap fish. Harpoon, green stick, chunking, kite and spreader bars are all in the gear list, so the report says how you actually took it.

Flatfish7
Winter flounder, fluke, yellowtail, grey sole, dab, windowpane, Atlantic halibut.

Other4
American eel, shad, sea raven, northern puffer.
And how you took it
Live bait or jigging. Drifting, trolling, anchored, surf casting or hunting. Then the long tail a commercial boat actually uses: harpoon, green stick, wire line, tube and worm, spreader bars, umbrella rigs, chunking, deep dropping, slow-pitch and downriggers.
Nothing there is also a report
Ran out to the usual spot and found empty water? Say so. Birds, birds over bait, or nothing at all is a sighting in its own right, and it is the report that saves the next boat the run.
The bay is only as good as the boats on it.
Closed beta while we get the right crews on, and Cape Cod Bay comes first. If you work Buzzards Bay or the Gulf of Maine, put your name in anyway and we will tell you when it opens up.
