Depending on how often I use my boat, I usually replace the yellow bow roller at least once a year. I rotate it by hand to keep it from wearing in one specific area. The yellow from the roller will wipe off the gel coat using hand pressure. Not a biggie.
I am looking into what it would take to design a roller with bearings. This would help nearly ALL BCB model as as they are all power loaded.
My hooks on my rear straps have lost some of the coating. Its from the pressure of winching the rear down, and the boat shifting on the trailer.
