A torpedo-launch arrangement that worked for one navy could fail for another because the weapon was only one part of an operating system. Hull form, crew practice, maintenance, the expected enemy, and the local sea state all affected whether a tactic remained viable. Short range and small hulls magnified those dependencies by keeping coastal craft tied closely to particular geography and weather. National solutions therefore diverged even when navies appeared to be solving the same problem. Copying a successful boat without its doctrine and support system could produce a poor result.

Why small craft become locally specialized
Hull, torpedo-launch method, crew practice, enemy, and sea state made attack boats more specialized to local waters than large ships.
