Just a question to see how many other people have had the same problem as me with a bad design fault on most board bags. I sail in salt water and keep my board in a board bag so the ropes on the roof rack don't destroy it but the zips are made of metal and so the salt after every session builds up around them, and after a few sessions the zips are completely broken and where the salt and water has corroded them. Why don't companies make board bags with strong plastic zips like wetsuit zips which dont break when in contact with salt water or use velcro or something else? any thoughts anyone? starboard?
