thank you very much, I was desperate to find data about the sail, I tried also to contact someone living near Buffalo to have measurements taken on the USS Boston sail!
Reading through the forum I understood you are very knowledgeable about US subs, may I ask another couple of questions?
-what is the distance from the extreme bow to the sail?
-about length, I have found 360' in most places, but also 361' 11", which one is true?
-and finally is it known the width of anechoic-tiled boats?
Thank you again for your help,
