01Tools

Five tools. One instrument.

Each panel a sharpened tool. Spot mapping down to the rock. Conditions: wind, pressure, water temp, moon phase, light hours. Session logging so tight you can replay a bite three years later.

01 · Spot mappingHand-pinned

The lake bed, mapped.

Drop pins for gravel, weed, silt, clay. Tag each with depth, bait history and bite count. Your swim becomes a chart, not a memory.

Gravel · 6ft Silt · 11ft Plateau · 8ft
02 · Watercraft EarsListening

Your bank-side intelligence.

Talk and walk. Ears hears your notes, timestamps them against the swim, and files them to the session. Read them back as a clean write-up.

Out now · v1.0 Public beta

It's out. Try it on your next session.

Add the water you fish most, start a session when you get there, and see what patterns emerge after logging everything that happens. True watercraft isn't given, it's earned. Start your first year now, or take a single session pass and see.

A session pass counts pound for pound toward your first year. Buy a pass, fish with it, and if you go annual the £4.99 comes off. £29 is the launch price, held until 30 August, £39 after.

You'll log in or create an account first (your Swimbooker login works), then enter code FIRSTYEAR29 at checkout for the £29 price. Access is added to your account automatically.

02Routine

Three phases. One craft.

You've been doing this a long time. The water, the bait, the read. That stays yours. Watercraft just sits alongside the three phases of every session, sharpening what you'd already do.

Step 01

Before the drive.

The session starts before the drive. You're reading the forecast, researching swims, checking your bait. Watercraft holds what's hard to keep in your head: every spot fished here, every fish off it, every condition that's worked.

  • Lake aerials: bars, plateaus, weed, snags
  • Per-spot memory: bait, depth, last take
  • Wind, pressure, fronts for the night ahead
Step 02

On the bank.

Your hands are full. Rods on the rests, eyes on the water, head in the moment. Watercraft is your ears for the rest. Every show, every liner, every take, every passing thought, captured by voice and tied to the swim. Nothing missed.

  • Dictation that runs in the bivvy, offline
  • Photos pinned to the spot and the hour
  • One tap to mark a moment, eyes stay on the water
Step 03

Packed down.

The patterns aren't new. You'd half-noticed them already. Which swim wakes up on a southerly wind. What time the takes come on a falling pressure. Seven sessions in, watercraft just brings them out properly. The hunches you had, now proven.

  • Patterns: pressure, wind, moon, swim
  • Bite-windows, sharpened by your captures
  • Your data, yours, always
03Booking sync

Booked there. Ready here.

Hundreds of thousands of anglers book their fishing through swimbooker. If you're one of them, watercraft is plugged directly into it, so every booking lands here automatically.

  • 01Bookings, auto-synced.Every swimbooker reservation appears in your watercraft calendar the moment you confirm it. No manual entry, no second app to update.
  • 02Sessions, quick-started.Tap a booking in your calendar. The session opens with fishery, lake, swim, dates, and rod count already in place.
  • 03History stays with the water.Last time you fished this peg, every spot, every fish, every note. Ready when you arrive.
  • 04Conditions on arrival.The brief already compiled for your booked date and location. Pressure, wind, moon, water temp.

Chapter 07 Pattern engine · learning as you log

Your sessions,
answering back.

The more you put in, the more it gives back. Every swim you pin, every take you log, every spot you save. Watercraft watches the shape of it. Then it starts showing you the patterns you were already feeling, just sharper, sooner, and backed by your own data.

It doesn't know anything I didn't already teach it. It just remembers all of it, at once.

Seven sessions in, it told me what I half-suspected. That's the bit that got me.

05Questions

Before you commit.

A few things worth saying plainly.

01

What is watercraft?

A precision logging instrument for carp anglers, and a place to learn the practice. Map the swim, record the session, watch the patterns surface across the year. It also teaches you the conditions, observations, and patterns that have helped anglers throughout history capture their target fish.

02

It says public beta. What does that actually mean?

It means the app is out, it works, and you can fish with it on your next session. But it is version 1.0 and it will not be perfect. Some things are still settling. If you hit something odd, tell the team and it usually gets fixed within the week. That is the trade: you get it early and rough, and you get a say in how it ends up.

03

Who is it for?

Carp anglers serious about the water, at any stage of the practice. Some already keep notes, watch the conditions, and record every session. Others are just starting, knowing they want to fish this way but unsure where to begin.

04

Who's building it?

Built by Alfie Tilley and Keanu Griffin (co-founders of swimbooker), in partnership with Scott Lloyd (professional carp angler) and Tom Wilshaw (professional angler & creative), alongside several other anglers and industry stakeholders who've spent years fishing seriously without a tool fit for the way they fish. The team is deliberately small; the relationships with the anglers shaping it are deliberately deep.

05

It's out. What happens now?

watercraft is live on the App Store and Google Play, in public beta. From here it is weekly builds: fixes first, then whatever early users ask for most.

06

Will it work offline at the bank?

Offline access is included. Maps, swims, dictation and session logging all work without signal. Anything you record syncs the moment you're back in coverage.

07

What platforms does watercraft run on?

iOS and Android, both live now. Web access will follow. The app is designed mobile-first because that's where session work actually happens.
