Was a degaussed steel or wooden hull better for trawlers sweeping magnetic mines?
Short answerEngineers preferred degaussed steel, but trawlermen liked wooden hulls because they did not depend on degaussing discipline.
NotesTechnical optimization and operating convenience point toward different choices. A degaussed steel hull offers stronger performance and more advanced engineering. Wooden construction avoids dependence on remembering and maintaining the degaussing state. Sailors and designers can therefore rank the same minesweeping solution differently.
