I'm having a problem with holes at the back of my neoprene sprayskirt. These seem to be the result of chafing from my towbelt strap/buckle but I'm not sure about that. I've tried re-arranging the towbelt -moving the buckle- but it doesn't seem to have solved the problem. The towbelt is a NorthWater 'belly pack' style where the belt and buckle is at the back during normal paddling. https://shop.bodyboatblade.com/coll...roducts/north-water-dynamic-water-sea-tow-pro It is impressive how much water can get into the cockpit through a couple of 1/2" holes when the conditions are right (or wrong, depending on your point of view!). A paddling friend just told me that he's had a similar (cause unknown) problem. Have you experienced this? Any hints? I really like the belly bag towbelt style, and don't want to buy a PFD with a 'rescue belt' built in, if I can avoid it.
