Once a year
Barnacles and tubeworms set hard. Scraping them off takes the coating too, and the boat runs fouled for most of the year.
Keel is on its way
What’s under your boatright now?
Most owners don’t know until the boat comes out of the water. By then, growth may already be costing you fuel, speed and money.
cleanboat cleans your hull with an underwater robot, right in your marina.
- No divers
- No need for you to be there
- No surprises when the boat comes out
- An inspection video and operator report after every visit
A dirty hull costs you every time you use the boat.
Regular cleaning is a fraction of the price you really pay. Big bills come when you keep it dirty:

Figures from research on ships. Small boats differ in size and speed, but the physics of a rough hull is the same.
- 02Hard growth is more expensive to clean and often means hauling the boat out
- 03Growth damage adds to maintenance costs
- 04Hard cleaning means recoating and repainting
This can add up to thousands of euros a year in hidden costs you thought were normal. No one told you there’s another way, with no surprises and nothing for you to worry about.

What Keel takes off.
Drag across the picture. On the left, a hull left for a year. On the right, the same hull kept clean with a visit every 8 to 10 weeks.
Illustrations, not customer photos. Every real visit is filmed, and the film goes into the owner’s account.
Why every 8 to 10 weeks
Clean more often, scrape less.
A diver or a haul-out costs enough that most owners clean once a year. That price sets the interval, and the interval decides whether the coating survives the cleaning.
Every 8 to 10 weeks
Keel lifts off soft film and early weed, which sit on top of the coating. Shells don’t get the time to cement themselves, so the coating lasts.
We come to the boat. The boat stays put.
Our operator flies the drone from the pontoon and stays out of the water. Your boat stays in her berth, and you don’t need to be there.

Keel does the work
Flown from the pontoon, the drone lifts soft growth before it can bond to the coating.

You see your hull
A film of your hull after every visit, with notes from the operator.
No one likes unexpected bills.
cleanboat saves you time, money and worry about hull maintenance. Keep your budget predictable and your running costs low with our annual plan.
We take care of your boat. Your film and the operator’s notes reach you as soon as the job is done. We come back before the build-up gets bad again: five times a year. That’s it.
From €645 a year up to 8 m, €1,190 up to 14 m. Longer boats and multihulls are quoted individually.

- The annual plan is billed annually in advance and covers five scheduled visits between March and November, 8 to 10 weeks apart.
- Boats over 14 m and multihulls are quoted individually. The per-metre rate is indicative.
- Every visit: the hull, waterline, rudder and propeller cleaned from the pontoon, a film of the hull and notes from the operator. Nobody goes in the water and the boat stays in her berth. No keys to leave, and you don’t need to be there.
Every plan comes with a berth in the club.
Once a month we get owners together on the water or on the pontoon. Your plan is your membership, so there is nothing else to join.

For marinas: cleaner hulls on your pontoons.
We film every hull we clean, and its owner gets the film. Your marina buys no equipment and hires nobody, and we’re open to sharing revenue with marinas.
Talk to us about your marinaQuestions owners ask
What is cleanboat?
cleanboat cleans boat hulls with a small underwater drone called Keel, five times a year, on an annual subscription. After every visit you get a film of your hull.
How is the hull cleaned without a diver?
An operator flies Keel from the pontoon. The drone works the hull where the boat floats, so there is no haul-out and nobody enters the water.
How much does it cost?
Prices follow length overall (LOA) and include VAT. The annual plan of five visits is €645 a year up to 8 m, €845 up to 10 m, €990 up to 12 m and €1,190 up to 14 m, billed annually in advance. A single clean is €150, €190, €250 or €300. Boats over 14 m and multihulls are quoted individually.
How often is the boat cleaned?
Five times a year, between March and November, 8 to 10 weeks apart. You choose the first date when you book and the other four are scheduled for you.
Where do you operate?
Today we work at five marinas in Portugal: Cascais and Oeiras in the Lisbon area, and Lagos, Vilamoura and Portimão in the Algarve. Spain and France are coming soon.
Do I need to be at the boat?
No. We work from the pontoon, and the film of the hull is in your account the same day.
Why clean so often?
Every 8 to 10 weeks, growth is still soft and sits on the coating, so it comes off without scraping. Research on ships shows even a thin slime layer can raise fuel use and emissions by 20 to 25% (IMO).
Can I cancel?
Yes. You can cancel the renewal at any time from your account, and consumers can withdraw from a new plan within 14 days of booking.
What is the cleanboat club?
A monthly get-together for owners on a cleanboat plan. Membership is included with every active plan.

Rather talk it through?
Leave your number and we call you. Our AI assistant picks up first, asks two or three quick questions, then puts you through to someone from the crew or books a time that suits you.
- Our AI assistant calls you and says straight away that it is an AI.
- It asks who you are and, for owners, the boat and where she is kept.
- Then someone from the crew takes over, or you agree a time for us to call back.
