Water Rat plans come as four sheets giving the details required to build both the 9ft and the 10.8ft versions, and are available in either metric or imperial measure (please specify your preference). They come in printed form (4 sheets of A3-sized paper) or as a pdf file sent via email for you to print out. The scale will only be correct if printed on A3, but that is not important as all of the measurements are listed on the plans, so you could even work from ‘Letter’ sized prints. The plans have plenty of detail, but the instructions are limited to what I have printed on the plans sheets themselves – this is a very simple boat, and does not require the instruction books which I send out with my more serious plans.
Basic plywood requirements are two sheets of 6mm/1/4″ marine plywood. The boat can be built from 4mm/5/32″ ply, but additional bottom panel stiffening is recommended.
