Passerello Intelligent access control for yachts
Yacht access control, reimagined

Your old remote —
Not gone. Just forgotten.

Your existing RF remotes keep working — every OEM control, every fob, exactly as before. Passerello™ adds what was always missing: smarter, more convenient control from the iPhone you always have with you.

Not Gone Just Forgotten — Passerello™ works alongside your existing OEM controls

The app

What you'll actually see on your phone

Simple, clear and clean — exactly what you need, where you need it.

Passerello™ app — passerelle control screen Passerelle mode
Passerello™ app — bathing platform control screen Platform mode
Designed for the stern

One screen. Four buttons. Total control.

The motion screen is intentionally minimal — large touch targets, clear direction labels, and immediate feedback. No menus to navigate mid-manoeuvre.

Mode toggle — switch between Passerelle and Bathing Platform with a single tap. The controller routes commands to the correct OEM automatically.
OEM status indicators — LIGHT and POWER show live feedback from the OEM system on PRO units, so you know the hardware state before touching a button.
Authenticated as — the logged-in user is always visible, so a captain can verify who is in control at any moment.

Core features

Security by design, not by configuration

Every design decision starts from the assumption that access must be revocable. That philosophy runs through the entire system.

Instant revocation
Remove any user's access in seconds — from anywhere. No factory reset, no hardware changes, no waiting.
Time-bounded access
Set a Unix expiry for each user. Charter crew, guests, and technicians lose access automatically when their window ends.
Per-user permissions
Crew members can be limited to passerelle only. Guests can be granted platform access. Granular, per-vessel control.
Drop-in installation
Fits in parallel with your existing OEM wiring. No modifications to the passerelle or platform hardware required.
Offline-secure by design
No Wi-Fi or network stack on the device. All credential validation happens locally. BLE proximity enforced.
Anchor chain counter
Integrated reed-switch chain counter on PRO units. Metres out displayed in the app with automatic NVM persistence.
BLE
Proximity enforced — ~10m range. No network stack on device.
iOS
Native iPhone app. Android in development.
6 / 8
Channel relay boards. BASIC (passerelle) and PRO (full) variants.
OTA
Over-the-air firmware updates via BLE. CRC32 verified.

How it works

Up and running in minutes!

Installation requires no tools beyond a screwdriver. Our registered installers across the UK, France, Italy, and Spain can handle the fit if preferred.

01
Controller installed
Smart controller wired in parallel — your existing OEM system, remotes and fobs all continue to work exactly as before.
02
Owner onboarding
Owner sets their admin key on-device — it never leaves the controller, never stored on our systems.
03
Users provisioned
Add crew and guests via the app or web portal. Each user gets a unique, time-bounded credential.
04
Full control
Move the passerelle, manage the platform, monitor chain length. All from the iPhone, within BLE range.
