Query: If it racheted, it might work

I received this item as a very nice gift to lock my surfboard. Unfortunately there's no way to get the straps tight enough. Anyone could pull them to a thinner part of the surfboard. The only way to tighten is to pull tight. With thick straps this is not effective. I'm not sure why people patent and sell things that clearly won't work.
