And that was the intention of hooting steamship crews, who used it to describe the huge square-rigged sailing vessels that were valiantly challenging the coming of steam on world trade routes. But the jibe became an accolade. For in truth, in their 50 years of useful life, the windjammers expressed the consummate majesty of sail and the climax of centuries of glorious evolution.
