SAIL COMPARE ... overlays Membrain results for comparison

Sail Compare allows North Designers to compare sail shapes between on-the-water sail photos with Membrain-predicted shapes or between two different Membrain sail shape tests. It is used to refine North’s software tools allowing North Designers to more accurately match customer requirements.
