In a way, the line "our ship is well-rigged and sails like the wind" is completely at odds with the crew and heavy guns: the frigate was the former, and the first-rater the latter, and was just too big to sail fast. One or the other may therefore be poetic hyperbole, or is it a borrowing from another tale? If Quaker was a sloop or smaller, it is unlikely she'd have rated a Captain, but a Commander, the rank below. Is this the same Quaker?
