Rigdon/Gulfmark/ TDW GPA 640's

Anyone on here have experience on the old Rigdon boats? Wondering what the consensus was on Performance, reliability, etc.

Did a 30 day contract transit with them when they were fairly new. They needed an engineer to bring the boat back to Louisiana from Trinidad. The Chief engineer had a DDE or OSV license which would not cover the route the boat was going. I thought the boat was well equipped and built. However maintenance seemed to be confined to changing oil. The Cummins engines were state of the art at the time but now??

Thanks, I appreciate it.

Their pump rate was less desirable, compared to TDW, ECO and HOS boats.
