TIMBER LIST FOR HULL, DECK & BULKHEADS
The following timber list is for construction of all structural timberwork for hull, deck, bulkheads, keel deadwood and skeg. Allowance has been made for reasonable wastage and scarphing. Large timbers can be laminated from smaller sections if necessary. Timber is to be selected, free of knots, shakes fractures etc
Plywood areas included for decks assume all plywood thickness, ie no teak coverings. If teak coverings are to be used then the total plywood thickness can be reduced by 6mm and covered with 6mm teak bonded in epoxy. At the bottom of the list are adjustments to make to the plywood quantities if you use teak coverings.
Building stocks and temporary timberwork are not included. Note that this hull must be built over temporary male station formers, not over permanent bulkheads. This temporary timberwork can be made from any stable low cost timber. |
