Windsurf Calculator by James Douglass

Windsurf Calculator is something I stumbled upon years ago. I found it in a blog by an avid windsurfer named James Douglass. He’s a marine biology professor at Florida Gulf Coast University. Douglass had posted on his website an excel spreadsheet that is an “Automatic Windsurf Calculator” used to calculate optimum board sail and fin size based on your weight, skill wind etc.

I have it here for download: Automatic Windsurf Calculator or you can access his page directly here: James’ Blog: Updated Automatic Windsurf Calculator Online ( Either way I encourage you to check out his website:
