Mark,
I wrote this in an earlier thread. Since I have been down this road myself I thought I would share it with you and save you some time searching.
"I don't think you will be able to get Ericson original equipment replacements for your Rub Rails. Pacific Seacraft was bought by another company and sold off the Ericson assets separately. The person who answered my inquiry could not tell me to whom. From the research I have done so far, including reading some earlier threads, I would suggest Checking out Port Supply and MESCO for possible Aluminum replacements. Otherwise, check out TACO Metal. An alternative, and maybe the simplest, would be metal rails with vinyl inserts from West Marine. You could have your local marina order or install them if you don't want to tackle the job on your own."
