Mobile Boat Detailing
Hull, deck and cabin cleaned with marine-safe products and techniques — built for an environment that attacks gel coat, upholstery and metalwork all at once.
Gel coat is not car paint.
Gel coat is thicker, more porous and oxidises differently to automotive clear coat. It chalks under UV rather than swirling, and it stains from waterline scum and rust runs in ways paint does not. The products and the technique both change accordingly.
The waterline tells the truth.
Whatever the water has been doing to the hull shows in a band at the waterline — scum, staining and growth, depending on where the boat sits and for how long. It is the hardest part of the hull to bring back and the most obvious one when it has not been touched.
A cabin that never fully dries.
Marine interiors deal with damp constantly. Upholstery holds moisture, vinyl and canvas mildew, and the lockers and bilge areas are where a smell starts long before anyone notices it in the cabin. Cleaning the visible surfaces alone does not solve it.
Timing matters more than it does on a car.
A boat cleaned before it goes under a cover for the season is a very different job from one cleaned after. Salt left on metalwork over winter keeps working, damp trapped under a cover grows what it is going to grow, and a hull put away with a scum line comes out in spring with a stain rather than a mark. If the appointment is going in ahead of storage, say so when you book — the order of work changes.
Four moments worth booking boat detailing for.
The work is the same either way — these are the times it makes the most difference.
It is going under a cover for the winter
A hull put away with a scum line comes out with a stain. Salt keeps working in the dark, and damp under a cover grows whatever it is going to grow.
Book before haul-out →There is a brown line along the waterline
Waterline staining is mineral and biological, keyed into the gelcoat while the boat sat in the water. It responds to the right product and dwell time, not to scrubbing harder.

Launch day is coming and it has sat all winter
Six months covered leaves chalky oxidation on the topsides, mildew on canvas and vinyl, and a cabin that smells shut up. Far easier on the hard than in the slip.
Book the spring prep →It is going on the market or up for survey
A buyer forms their opinion from the topsides and the cabin smell before they ask about engine hours. Chalky gelcoat reads as neglect even where the mechanicals are perfect.

Marine surfaces do not behave like automotive paint.
Gelcoat is porous and it chalks as it oxidises rather than dulling the way a clear coat does, so it takes a different compound and a different pace. Add canvas, vinyl, non-skid and stainless — four more materials with four different tolerances — and the reason a boat is not simply a large car with a pointed end becomes clear. Using automotive product on gelcoat is how people end up with a hull that looks worse afterwards.

In the slip, on the hard, or on the trailer
Which of the three it is decides what can actually be reached — the bottom and much of the topsides are only properly accessible out of the water. Telling us which at booking is what stops half the job being impossible on arrival.
The parts that decide the result.
At the marina or on the trailer.
Boats get detailed where they are — in the slip, on the hard, or on a trailer in a driveway. Which of those it is changes what can be reached, so it is worth settling when the appointment is booked rather than on arrival.
Before you book.
Can you detail a boat in the water?
The deck, cabin, metalwork and topsides yes. Anything below the waterline needs the boat out of the water, so what is reachable depends on how it is sitting.
Do you use marine-safe products?
Yes. Both because gel coat and marine upholstery need different chemistry to automotive paint, and because of what runs off into the water around a marina.
Will the waterline scum come off?
Usually a great deal of it. How completely depends on how long the boat has been sitting and what the water is like where it sits.
Can you deal with mildew smell in the cabin?
Cleaning addresses mildew on surfaces and in upholstery. If the source is standing water, a leak or something in the bilge, cleaning treats the symptom — we will tell you what we find.
Do you detail boats on trailers?
Yes, and it is often the easiest option, because the whole hull is reachable in a driveway or yard.
How much does it cost?
It depends on the size and condition of the boat and your location. The exact total is shown and agreed in the booking flow before anything is confirmed.
Should I book before or after the season?
Before storage is the more valuable appointment. Salt left on metalwork and a scum line left on the hull keep working all winter, and both are much harder to reverse in spring than they were in autumn. A pre-season clean is mostly cosmetic by comparison.
Can you wax or seal the gel coat?
Yes, and on a boat it earns its place — gel coat chalks under UV, and a protective layer is what slows that down. It is discussed against the state of the gel coat, because on heavily oxidised surfaces compounding has to come first or the protection just seals in the chalk.
What every mobile boat detailing includes.
- Hull washFull hand wash of the hull sides and transom with marine-safe products.
- Waterline treatmentScum line and staining treated directly rather than washed over.
- Deck and non-skidDeck surfaces cleaned including non-skid, where dirt sits below the surface.
- MetalworkRails, cleats and fittings cleaned and rust runs addressed.
- Cabin interiorUpholstery, hard surfaces and lockers cleaned throughout.
- Vinyl and canvasSeating, covers and canvas cleaned and treated where appropriate.
- Glass and hatchesWindows, hatches and companionway glass cleaned inside and out.
- Final inspectionWalked with you before we leave.
What mobile boat detailing actually looks like.
Hull, deck and cabin cleaned with marine-safe products and techniques — built for an environment that attacks gel coat, upholstery and metalwork all at once.
Rinse after every salt outing
Fresh water over the hull, deck and especially the metalwork after saltwater use. This one habit prevents more corrosion damage than anything a detailer can do afterwards.
What actually happens on the day.
The appointment follows the same order every time, because the order is what makes the result last.
In the slip, on the hard or on a trailer — each gives different access to the hull. This is agreed before the appointment rather than discovered on the day.
The interior is done before the exterior, so nothing brought out of the cabin lands on a cleaned deck.
Deck and fittings, then down to the hull sides and the waterline last, where the heaviest work is.

What mobile boat detailing fixes — and what it doesn't.
- Comes offSalt film, general grime, light waterline scum, surface staining, and interior soiling in upholstery and vinyl.
- Usually improvesChalky, UV-oxidised gel coat improves substantially with cleaning, but heavy oxidation needs compounding and is a restoration job.
- Needs specialist workBlistering, deep gel coat damage, structural osmosis and antifouling work are outside a detail and we will say so rather than take them on.

How to keep it.
None of this is a warranty — it is just what actually makes the result last, from having watched what undoes it.
- Rinse after every salt outingFresh water over the hull, deck and especially the metalwork after saltwater use. This one habit prevents more corrosion damage than anything a detailer can do afterwards.
- Ventilate under the coverA sealed cover over a damp cabin is how mildew starts. Airflow matters more than the cover being tight.
- Watch the metalworkRust runs from fittings stain gel coat, and the stain is far harder to remove than the rust that caused it. Catching a weeping fitting early saves the surface below it.
- Keep the waterline in checkScum builds continuously wherever the boat sits. Addressing it between details — rather than only at the annual clean — keeps it a mark rather than a stain.
