As an idea, you may want to give people some tips on how to measure their boat. We found the easiest way was to take (masking tape) a tape measure to the boat and then calculate and note the 16" intervals to take the circumferences with a dressmaking measure. And for the other measurements we put masking tape across the boat with a mark in pencil for the point we used to measure the cockpit.
Here are the measuring charts you will need to complete if we don't have your boat 'pattern' on file (note inches not centimeters) with the measurements for a conventinal rigger 1x boat or for a wing rigger 1x boat (the chart is different for measuring). For doubles and pair measurement charts go to the boat bags page
