Paint Calculations

Depending on what part of the boat you are painting this will affect the amount of surface area you will need to cover.

Long Keel (displacement).

length x (breadth + depth) = square metres.

Medium Draft Sail Boats (semi-displacement)

Length of waterline x (breadth + depth) x 0.75 = square metres.

Deep Keelers, Racing Yachts.

Length of waterline x (breadth + depth) x 0.5 = square metres.

Topsides

(overall length + breadth) x free board x 2 = square metres.

Decks - (No allowance for cockpits/coamings).

(overall length x breadth) x 0.75 = square metres.

All dimensions in metres.
