Based upon recommendations and my quest for drawings and charts to help me visualize the controversial aspects more clearly, I have purchased "The Ship That Stood Still".
My what small print!
What an incredibly well researched book. Well documented, footnoted and annotated!
And my word, how clear the diagrams are... just what I was looking for!
I skimmed the book for two hours from 1am to 3am last night, and feel more confident that I agree with how many ships were in the area, and now understand how they could both report what they saw, and how close they might have been.
Thank you for recommending this one to me!
I will pursue a copy of "The Indifferent Stranger" next...
