TIMBER LIST FOR HULL, DECK, BULKHEADS & INTERIOR JOINERY

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

This list is as used in the construction of the first boat and is for timber in sizes as bought. Most of it was machined to sizes needed before delivery but larger sizes were machined at the boatyard to what was needed in the boat.You may decide to buy larger stock and machine in-house or to buy all machined to size. Use this list as a guide only.

The plywood list is for building without glass sheathing. If built with glass sheathing then some of the sheet quantities will change.
