THE DESIGN BRIEF

The Sportz 16 brief was for a fast and thrilling racing yacht with excellent performance high on the priority list, but yet at the same time it had to be easy to sail, with a comfortable cockpit for weekend day sailing for the family and a competitive racer without breaking the budget. The cockpit size and deck layout had to be carefully balanced to achieve this 3 fold role. The result is an attractive, easily to handle, 'club racer' or weekend day sail.

MATERIAL 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 10% wastage, with the exception of the building stocks and chipboard, which are net. These figures allow for building with 1/4 in (6mm) Kiri or Western Red Cedar skin for the hull and 1/4 in (6mm) Gaboon plywood for the deck and cockpit sole. All frames and bulkheads are CNC cut and constructed from 3/8 in (9mm) Gaboon Plywood.
