Figure 24 & 24A:

If you are intending to go with single layer planking then some bevelling of the tapered edge of the plank will be needed. To gauge the amount of bevelling required test fit the plank into position and take note of the location and amount needed to be bevelled. Sand as required to obtain an exact fit but remember final sanding and fairing of the hull will uncover any poor bevelling resulting in a gap usually where you don’t want it to be. If you are going use a second planking layer then bevelling is not required as the second layer of planking will cover any gaps in the first. The second layer of planking is usually of thin veneer of 0.5mm so again bevelling is not required in this instance.
