Hip Clearance The SEARUNNER CONSTRUCTION MANUAL (described in Section 18) coxnprises the balance of the plans. Since its' first publication in 1972 it has been widely heralded as a "Bible" for back yard building. On the bottom of the pile of plans (photo at left) are the full size framing patterns, 42" x 94". These are rolled out onto the plywood from which a given part is to be cut. Marking through the paper onto the plywood is done with an awl, so that when the paper is removed, the plywood has marks describing the perimiter of the part. These marks are joined with penCil lines and the part is then cut to the lines. T<strong>here</strong> is no measuring, no "table of offset". Accuracy is assured by reduCing builders' error, and frame cutting goes very fast. It's a pleasure. Under the eyeglasses ( in the photo) are the Roman numeraled sheets, 26" x 42" listed on the "Table of Contents", and on top of those are the numbered sheets, l8"x42 ". These working drawings graphically communicate each part and its relationship to other parts. Following are some photo-reduced samples of the plans:

T he same strongback can be used for both floats and main hull. Mainhull frameplan for BROWN 37 shows how the boat's interior is established in the framing stage. Glue-strips and cut-outs are installed while the frames can be laid flat on the bench. When the hull is finishe d, the basic interior is established.
