Updates to Pixie Plans
Reading from the left of the drawing the measurements are: 5, 140(horizontal dimension), 30, 100, 150, 183, 195, ALL 500 (horizontal dimension), 195, 180, 145, 90, 140 (horizontal dimension), 70 The cutout in the jig doesn't have to be too accurate as the ply will form a fair shape.
The rudder drawing reads: Steering is more positive if "Ackerman Linkage" is used (as on the front wheels of cars). This can be done by making cranking tillers (angle in 10deg) as shown dotted below
The 3225 means 3.2in x 2.5in (80mm x 60mm) as a minimum. Most beach cats use similar spars so there is no problem using second hand spars from other boats. You just have to accept a few odd holes here and there, but I have never found that to be a problem.
The mast can be longer if you want more head clearance under the boom.
