A while ago I purchased Nick Schade’s book The Strip-Built Sea Kayak. From it I built his Guillemont. I also liked the look of the Great Auk but liked the speed and ease of ply construction stitch and glue.
I drew up the forms and used these to get the general shape. All went very well. I found some 2.5 mm ply $5 per half sheet 1200 mm x 600 mm. This ply comes from Asia between boxes of food ??
