The quoted officer is willing to learn from the Americans and praises both their equipment reliability and their professional cooperation. He nevertheless argues that British submarines compare well as fighting machines and expresses confidence in taking one into the Inland Sea. His final judgment names the German 500-ton U-boat as the war's outstanding submarine because of its sinking record and persistence in combat. Machinery quality, crew confidence, operational suitability, and combat results can therefore produce different answers to the question of which design was best.
