LIST OF MATERIALS FOR HULL, DECK & SUPERSTRUCTURE

The following lists of materials are approximate and intended only for calculation of approximate costs. Theyare not intended to be used for the ordering of materials for construction.

Lengths and areas are based on the actual amounts to be used in the vessel without any allowance for building stocks, temporary framing, bracing etc nor for wastage in cutting to size and shape as required. Wastage on flat bars, tubes etc will be minimal whereas that on plate will be dependent on the skill of the builder and will be in the range of 5% to 20%.
