The gap in the vessel’s history is now between 1972 and the fall of Saigon and approximately 2006 when it was operated by Allen Marine in Sitka, Alaska, ferrying cargo is SE Alaska.
It is my understanding it either swamped or went on its side in the Philippines and was salvaged and converted to a barge-like vessel without most of its top deck and 28 feet shorter than original.
After that, it maintained or received a new CG certification so somebody spent some money keeping that certification. And it had a a loading ramp installed on it. So the last 50 years or so, is a mystery. How do I fill in those years?
