Clinker boats
Just making another clinker boat, a commission. 😀 This is the method I have devised to space the planks. Wrap a strip of paper around the frames to find the length. Draw a line, easily divided to the number of planks required, slightly longer than the widest frame. Join the divisions to a point square to the centre, the further away the better. Place the paper strips so they touch the outer lines, mark in the divisions. Transfer the marks to the model. On a clinker boat, start the width of the lap way from the keel.
