After hitting a few logs while sailing and frustrated with blowing through the bottom of slot boxes, and the lack of unavailability, I decided to upgrade my Starboard Kode Wave Twin board to US boxes.
This repair took me way to long, mostly because of the colder winter than usual and not wanting to keep my shop heated on the cold days. Here’s the basics of what I did, I’m by no means a pro, but I’ve repaired a few boards for myself, and at windsurfing centers as an instructor.
