12. Bow Planking:
During the course of planking you might in some bluff bowed ships such as ‘Endeavour’ or ‘Bounty’ for example be struck with what appears to be the need to bend a plank laterally across its width as is seen in figure 15B. This is real problem as the lower edge of the plank bulges out causing a clinker built look or similar to a weather boarded house where the upper plank wants to overlap the lower plank. In this situation a technique called spilling needs to be done to the plank. Spiling is described later in this project under its own heading.
In a normal hull more than likely a drop plank would be needed rather than what is described above. Drop planks are required where bunching of the planks occurs and excess tapering would result in splinter or sharp pointed planks.
