Boat and watercraft detailing

Gelcoat, vinyl, canvas and cabin — on the trailer, on the hard or in the slip.

Marine

The hardest environment there is

A boat lives under continuous UV with nothing overhead, in water that is either mineral-heavy or salty, and spends long stretches under a cover where air does not move. Nothing else we work on gets all three at once.

Three problems come out of that, and between them they account for most of what we are called about: oxidized gelcoat, staining at and below the waterline, and mildew in the vinyl and the canvas. All three are preventable and all three get expensive if they are left.

None of it is cleaned the way a car is. Gelcoat is a resin surface rather than paint, marine vinyl reacts badly to almost everything sold for household cleaning, and non-skid decking must never be given a finish that makes it slick.

Almost every heavy mildew job starts with a boat that was put away dirty.

What we service

From a jet ski to a cabin cruiser

Length decides the scope; where the boat sits decides what can be reached. Both are asked at booking.

  • Personal watercraft

  • Pontoons

  • Ski & wake boats

  • Center consoles

  • Cabin cruisers

Bowriders, bass and fishing boats, deck boats and sailboats are all covered. Larger vessels are taken on where the site and the season allow, and are quoted after a look rather than booked online.

Where it sits

Access decides what is possible

This is the first question we ask, because it rules whole parts of the job in or out before length matters at all.

On a trailer

The straightforward case. Everything is reachable, and the boat can be moved to somewhere with room to work around it.

Everything possible

On the hard, on stands

Full access to the hull, which is the only position where anything below the waterline can be addressed.

Hull accessible

In a slip

Topsides, deck, interior and canvas only. Everything is worked from a dock, nothing may go into the water, and several products are ruled out for that reason.

Above the waterline

Under cover or shrink wrap

Has to come off before anything starts. Worth planning around, because removing and refitting it is time before any cleaning happens.

Allow extra time

Surfaces

Why nothing here is cleaned like a car

Every surface on a boat has its own rule, and at least three of them are ruined by products most people already own.

Gelcoat
A pigmented resin layer, slightly porous, that UV breaks down at the surface. Light oxidation polishes out; moderate needs compounding; heavy may need wet sanding. Every stage removes material, and there is a finite amount of it.We will tell you when a hull has been compounded too often to take more.
The waterline
The yellow-brown band on a boat that sits in the water is tannins, algae and mineral scale. It needs a dedicated hull cleaner with dwell time — scrubbing an oxidized hull to remove it takes the gelcoat with it.
Marine vinyl
The mildew is usually growing in sunscreen and body oils on the vinyl rather than in the vinyl. Bleach destroys the stitching and strips the UV inhibitors; alcohol-based cleaners pull the plasticizers out and the surface cracks along the folds.
Canvas and enclosures
Acrylic fabric with a water-repellent finish that cleaning removes along with the dirt, so it is re-treated afterward. Deep mildew staining is often permanent even once the growth is killed.
Non-skid decking
Textured on purpose. Brushed rather than wiped, and never sealed with anything slick — a shiny non-skid deck is a hazard rather than a finish.
Stainless and teak
Stainless resists rust but does not defeat it, so rails and fittings are polished and protected. Teak is cleaned with the grain and never pressure washed, which erodes the soft grain into ridges.

Scope

What is in, and what is not

Marine work attracts vague quotes. This is the line we draw, stated before you book rather than discovered at the dock.

What a marine detail covers

  • Hull and topsides washed, decontaminated and sealed
  • Waterline staining treated where the boat can be reached
  • Gelcoat polished or compounded according to how far it has gone
  • Vinyl cleaned, treated and protected with marine products
  • Canvas, bimini and enclosures cleaned and re-treated
  • Deck, non-skid, hardware, cabin and storage compartments

What is separate work

  • Anything below the waterline while the boat is in a slip
  • Bottom paint, antifouling and blister repair
  • Shrink wrap removal and refitting
  • Gelcoat repair, cracks and structural fiberglass work
  • Engine servicing, bilge pumps and anything mechanical
  • Upholstery repair where vinyl has already split

Timing

The two appointments that matter

Most owners book the first and skip the second. The second is the one that decides what next spring looks like.

  • Before launch

    The surface is reset and sealed while the boat is dry and accessible, so the season starts with protection on it instead of acquiring spotting from week one.

  • Before storage

    Salt, tannins and organic film left under a cover have months to work with no sun, no airflow and nobody looking. This is where the mildew jobs come from.

  • Rinse after every use

    Fresh water over everything, trailer included. Dried salt pulls moisture out of the air and keeps a wet film against metal indefinitely.

  • Let the cover breathe

    A cover strapped tight over a damp interior is an incubator. Vents and a moisture absorber prevent more mildew than any product removes.

Questions

Asked about boats

Can you detail my boat while it is in the water?

Yes, for everything above the waterline — topsides, deck, interior, canvas and hardware. Anything below it needs the boat on a trailer or on stands. Working in a slip also rules out several products, because nothing may go into the water.

Can faded, chalky gelcoat be brought back?

Usually. Light oxidation polishes out; moderate needs compounding first; heavy may need wet sanding before polishing. What decides it is how much gelcoat is left — on a hull that has been compounded repeatedly over decades there may not be enough to take another pass, and the honest recommendation becomes paint or wrap.

How do you clean mildew off vinyl seats?

With a marine vinyl cleaner and agitation, followed by a protectant. Not bleach: it breaks down the stitching long before it damages the vinyl, and it strips the UV inhibitors, which is what makes seats go hard and crack a season later. The same goes for alcohol-based and abrasive cleaners.

Do you do bottom paint or antifouling?

No. That is yard work rather than detailing, and it needs a haul-out and a different setup entirely. We clean and protect the surfaces above it.

How is a boat priced?

By length, by where it sits, and by condition. A twenty-two-foot pontoon on a trailer and a thirty-eight-foot cruiser in a slip share almost nothing, so a category price would be meaningless. Send the length, the position and a few photographs of the hull and upholstery and we will quote properly.

Will you clean the trailer too?

Ask for it and yes. It is worth doing on anything that has been in salt water, where the trailer usually has a harder life than the boat.
