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.

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.

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

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.

03

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.

04

What does "lifetime" actually mean?

One payment. Lifetime access to watercraft, including all future updates and features. No recurring charges or annual renewals. Your access remains active for the lifetime of the product.

05

Why is the cohort capped at 100?

100 is small enough that we can know who you are, hear your feedback, and let you shape the build. Bigger than that and the founder relationship becomes a mailing list. The cap isn't a tactic. It's the number we can actually engage with.

06

When does watercraft launch?

Public launch is late June 2026. Founder's Lifetime members get early access before that, with a direct line to the team. You'll hear from us the moment the build is ready.

07

When will I receive the metal card?

Engraving begins once your founder ID (numbered 001 to 100) is assigned. Expect a more specific arrival date shortly after purchase.

08

Will it work offline at the bank?

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

09

What platforms does watercraft run on?

iOS and Android at launch, with web access shortly after. The app is designed mobile-first because that's where session work actually happens.

One in a hundred.
