How much paint to use
How to calculate the area to be painted
| 1 | Underwater surface area of a sail boat (Fin keel) LWL x (B + D) x 0.50 = underwater area |
| 2 | Underwater surface area of a sail boat (Full keel/Bilge keel) LWL x (B + D) x 0.75 = underwater area |
| 3 | Underwater area of a motor boat LWL x (B + D) x 0.85 = underwater area |
| 4 | For the freeboard (Length over all + B) x (F x 2) = Freeboard area |
| 5 | For the deck (Length over all x B) x 0.75 = Deck area |
| Total litres required = | Total surface area (m²) |
| Coverage rate of relevant paint (m²/lt) |
| Key: | |
| LWL | Length at the water line |
| B | Beam (maximum width) |
| D | Draft (to the base of the keel) |
| F | Freeboard height (waterline to gunwale) |
