garboard การใช้

A drain plug hole about was drilled in the garboard plank on one side to allow rain water drainage.
Normally, the boats are built from the garboard up so that the upper plank overlaps ( aka hems ) the lower on the outside.
The garboard is the wale next to the keel; the gunwale is the top such plank and covers the heads of the timbers between the main and fore drifts.
The deck-beams, the stringers, the garboard-strake, the triple-expansion engine and other parts, have particular functions, and their characters are correspondingly distinct.
The hull, typically, consists of four strakes each side, the garboard strakes being wide giving a flat run to the transom whilst having a fairly sharp entry at the stem.
