I have a roughly 2000 PT 40. On the port side adjacent to the pilot house door there is a through hull that allows lines to be secured on the inside of the hull adjacent to the walkway. The through hull is about 3" by 7" and is oval with lashing horns on the inside part. It looks like it is made out of aluminum. We had a big storm come through up here in AK and the boat was heaving against the lines resulting in that through hole getting folded up and the lashing horn bent about 120 degrees. First of all, I don't even know what to call this part, and more importantly, where might I be able to find a replacement. I have looked at all the usual places with no luck. I appreciate any advice.
