Calculating needed paint quantity

Hull above the waterline    

2 x (total length + width) x average high between waterline and deck

 

Super structure                   

Total height  + 2x length  +  2x width minus window sections

Decks                                  

0,75 x total length x width minus super structure

Note: The above calculations are general guidelines. Exact needed quantities may proof higher.  Always calculate 10-15% additional material depending on application method and surface.
