I would appreciate any advice on layout to cutting out the scuppers on the gunnels in such a way that there is wood over where the seats and thwarts will go. I began trying a pattern of 3" solid and 3" cut but it doesn't lay out for every place I will need to attached the seats, thwart & yoke. Is it common practice to leave a bigger piece of solid in certain places breaking the regular pattern? or is there some other technique? All suggestions welcome!
