Coppercoat Antifoul
How much will I need?
To make it easy for you we have constructed a calculator to determine the amount of Coppercoat required. Simply click the style of boat you wish to coat, and fill in the waterline length, beam and draft (in feet). These calculators are designed to be a general aid – if you are unsure of the area to be treated, please contact AMC Ltd for confirmation of the quantity required.
Full Bodied
Motor boats, displacement yachts or full, long-keeled yachts
Medium Bodied
Large fin and skeg or bilge keeled yachts
Light Bodied
Fin keeled yachts

The Formula Used
To determine the quantity of Coppercoat required, calculate the hull area by simply multiplying the waterline length by the addition of the beam and the draft. Then, depending on the vessel, apply a factor:
- For full bodied craft such as motorboats or displacement and full keeled yachts, no factor is applied
- For medium bodied craft, such as large fin and skeg or bilge keeled yachts, multiply by a factor of 0.75.
- For light bodied craft, such as fin keeled yachts, multiply by a factor of 0.65.
If the calculation WBD measurements are in feet, multiply the figure by 0.093 to convert to square meters.
Given that Coppercoat has an effective coverage rate of 4 square meters per litre; divide this figure by 4 to determine how many litres are required.
Example 1
A 34ft motorboat, with a 30ft waterline length, a 12ft beam & a 2ft draft;
30 x (12+2) = 420 sq.ft, x 0.093 = 39.06 sq.m, / 4 = 9.76 litres required.
As Coppercoat® is supplied in 1 litre units, 10 litres should be used.
Example 2
An 8.5m fin keeled yacht, with an 8m waterline length, a 3.6m beam & a 1.5m draft;
8 x (3.6+1.8) x 0.65 = 26.52sq.m / 4 = 6.63 litres required.
As Coppercoat® is supplied in 1 litre units, 7 litres should be used.
