SHIPSKIN
Marine coatings, hull protection, and the calculators behind a well-painted vessel.
From sizing the wetted hull area and calculating antifouling to converting wet and dry film thickness, working out coverage, mixing the right thinning ratio, and estimating the paint bill, ShipSkin pairs free hands-on marine-coating calculators with practical guides and a richly illustrated museum. Paint smarter, protect longer.
Marine Coating Tools & Calculators
Free tools for every hull job — hull area calculator, antifouling paint calculator, wet film thickness converter, paint coverage calculator, thinning ratio calculator, and paint cost estimator.
Hull Area Calculator
Estimate the wetted surface area below the waterline from your waterline length, beam, draft, and block coefficient — in square metres and square feet — so you know how much hull you're painting
Antifouling Paint Calculator
Work out how many litres of antifouling your hull needs for a given number of coats, rounded up to whole tins, plus the total cost from hull area, coverage, and price per litre
Wet Film Thickness Calculator
Convert between wet film and dry film thickness using the paint's volume solids, with optional thinning — so you can check the coating with a comb gauge and build the specified dry film
Paint Coverage Calculator
Derive the theoretical and practical spreading rate of a coating in square metres per litre from its volume solids, target dry film thickness, and a loss factor for overspray and waste
Thinning Ratio Calculator
Work out exactly how much thinner to add to marine paint for a given thinning percentage, and the total volume once mixed — in litres or millilitres — without over-thinning the coating
Paint Cost Estimator
Estimate the paint cost of a hull job across a topcoat and an optional primer — litres, whole tins, and total cost from area, coats, coverage, and price per litre
Marine & Ships Museum
Wander an immersive museum of ships and the sea — the vessels from container ship to sailboat, the hull and its parts below and above the waterline, the shipyards, dry docks, and coatings that build and protect them, and the harbors and seamanship that guide them, each in its own gallery, so you can get to know the world of ships: how each one is built, what keeps it afloat and protected, and the craft of life at sea.

Fresh guides on antifouling and marine coatings, hull protection and cleaning, corrosion and surface prep, and ship maintenance, plus practical tips for coating and protecting every vessel.
