Abrasion

Also: chafe spot

Abrasion happens when the boat drags over stones or rubs against a backpack or bike. It weakens the coating before a hole appears.

Packraft Europe names strapping the boat to a backpack or bike as a typical cause. According to the retailer, Aquasure can also be applied preventively to heavily stressed spots. Alpacka uses Aquaseal for worn floor areas.
