Foil wings of the same shape often come in two or three different sizes, and each larger size is usually several inches wider. I created a vector graphics file to allow me to calculate mast height for each wing size AND keep the lean over angle the same. As an example I have two F4 surf wings size 1250 (27.5″ span) and 1700 (33.5″ span), when using the same 28″ mast on the larger wing I need to ease up on my turns to keep the tips in the water. So I want a taller mast that will allow me to lean over by the same degree and carve the same tight turns. This vector graphics file showed me how tall the mast needs to be to do the same turns.
Here is the file in both Adobe Illustrator (AI) and SVG format:
