I wonder what the actual percentage of warranty claims is for each type of product.
I bet boards are quite low. Sails are probably quite low too.
Things like booms and masts are probably higher and the hardest to prove fault.
From personal experience wetsuits are probably high. I've had a few fail. One had winter suit had no stitching at the groin
, another wore through at the groin within 3 uses and one came apart at the zip due to poor stitching. I've seen a lot of dry zips fail to but proving misuse ore failiure proved difficult.
