Perhaps I can be of assistance. The item you are looking for is the Ship's Manifest. It would provide a list of crew, passengers, all supplies and any cargo brought in before the boat leaves port.   

Dr. Moreau's name will not appear in the Manifest, and any search of Personnel Files will turn up zip. Not even an entry. Carla and Foy will appear on the manifest, but extremely minimal information in the Personnel Files. 

The only person who knows anything about Jahosafat is the Captain, and even he only has his copy of standing orders, which will reveal little if any personal information, but can be verified by the person who gave said orders. 

That about cover it, [@Lady Amalthea]?
