It is an option to have the Clipper corrosion protection on any 44. It can be ordered even if you aren't getting floats. It is recommended for ships based in coastal areas. All the alum panels are zinc chromated before assembly. It adds a small amount of weight but provides a lot of protection.
Before you blame Robinson, maybe some owners should consider equipping the ship for the environment in which it will be operated. Some may fire back and say it should be standard.... Well not all owners want the weight or have a need for it. As far inland as I am.....It would be a waste of money and just dead weight.
