Ahead

See fishing gear and floating hazards before your bow does.

An extra lookout that never blinks. Ahead watches the water in front of the boat and tells you what's there, how far, and how soon.

The problem

The lines you can't see.

Pot buoys, net floats and the lines between them are hard to spot from the helm, and they crowd the coasts cruisers love most: Galicia, Portugal, Brittany, Maine.

The flagged dan buoy is rarely the problem. Sailors tell us it's the dark can, the small white float, the weedy one with no flag, the one the tide has pulled half under. And off Spain and Portugal, the advice to stay close inshore away from orcas leads boats straight into the pot fields.

Catch one and the best case is a swim with a knife. The worst is a wrapped propeller, a damaged saildrive or rudder, and a passage that ends at the nearest port, or with a call for help. On a long coastal leg with a small crew, nobody can stare at the water for six hours straight.

How it works for you

A second pair of eyes at the bow.

01 / 03

Start a watch. Then get on with sailing.

One tap and Ahead keeps watch on the water ahead, hour after hour, while you trim, cook, navigate or rest. You can see at a glance what it sees and how far away it is.

02 / 03

Know what, where and how soon.

When something's there, you hear about it in time: what it is, which side, how far, and how many seconds you have. The alarm sounds at the helm, on your watch and on every device aboard, so the crew below hears it too.

An alert: fishing gear ahead, 120 metres off the port bow, 38 seconds away
03 / 03

A log of every watch.

Every sighting is logged with the time and place, along with the moments when glare or haze limited the view. Review a passage in seconds, and know which stretches of coast to watch closely next time.

What sailors told us

A watch you'll want to keep on.

We studied some eighty first-hand accounts of fouled props, near misses and watch apps that got switched off. Three lessons shaped Ahead.

A/004

Alarms worth hearing

Crews switch off alarms that cry wolf. Ahead speaks up for what's in your way, stays quiet about what isn't, and we treat every false alarm as a fault to fix.

A/005

Honest about its limits

Glare, haze, spray and dusk all limit what any lookout can see. Ahead tells you plainly when they do, so you never mistake silence for a clear sea.

A/006

Help if the worst happens

If a line does catch, a calm step-by-step checklist walks the crew through the first minutes, and the time and place go in the log for your insurer and your next passage.

Safety first

An aid to the watch, never a replacement.

The skipper and crew keep a proper lookout by sight and hearing at all times, as the collision regulations require. Ahead adds a second pair of eyes that doesn't tire, and it always tells you when it can't see well.

Roadmap

From sea trials to every boat.

2026

Sea trials

90 days of testing and data collection on the water ahead: Biscay swell, fog among the fishing nets of the Gulf of Cádiz, and the Strait of Gibraltar.

2027

Pilot season

Founding crews sail with Ahead in Atlantic Spain and Portugal.

2028

Launch

Open to cruising boats across Europe and the US East Coast.

Questions

Good questions, straight answers.

Does it replace a lookout?
No. It's an aid to the crew's lookout. The skipper stays responsible for the watch, as the collision regulations require.
What does it spot?
Fishing-gear floats and flagged markers, pot buoys, floating debris such as logs and pallets, and small craft that don't transmit AIS.
Will it bother me with alarms?
It shouldn't. It alerts you to what's in your way and stays quiet about what isn't. During the pilot we track every false alarm and fix it.
What if I catch a line anyway?
Open the checklist in the app: it walks the crew through the first minutes safely and logs where it happened.
Does it work at night?
The first season is designed for daylight and dusk, and the app tells you when conditions limit what it can see. Night watch is on our roadmap.
How hard is it to set up?
Quick, with no yard work. We set up every pilot boat in person.
Where can I use it?
The 2027 pilot runs in Atlantic Spain and Portugal. Wider European and US East Coast availability follows.
What will it cost?
We'll announce pricing before launch. It will cost a fraction of professional systems, and pilot boats get special terms.
What happens to my data?
It's yours. Anything we use to improve the service is opt-in, and we follow EU data-protection law.
