TIMBER LIST

The following list of materials is approximate and intended for calculation of approximate costs. We offer no guarantees of accuracy.

The list is for all timber in the construction of hull, deck and interior, including building stocks, temporary bracing etc. Allowance has been made in the quantities for about 20% wastage, with the exception of the building stocks and chipboard, which are net.

These figures allow for building with 6mm plywood skin for hull and deck. If you want to build with the optional 9mm hull skin then replace the 3mm plywood with 4 or 4.5mm thick, whichever is available in your area and replace 7 sheets of 6mm plywood with 7 sheets of 9mm. The extra weight of the increased plywood thickness will be approximately 30kg (66lb) with Okoume plywood.
