We could blame it on the full moon and miscommunication.
The etymology of the word and the evolution of mariners swords are two separate discussions. When asked what one would choose, it was narrowed to a rapier or basket sword. Further defined to the golden age. I am left defending my assertion that the same swords as appearing on land, would have been used aboard. Long ones and short ones. A couple of books such as one of the Gilkerson's
Boarders Away volumes and Neumann's
Swords and Blades of the American Revolution offer lots of late 18th century blades to compare for modern tastes.
My pressing for movie faults is because some are horrible with others plausible but the basis of my stance was regarding historical parameters. The original precept of the hypothetical was amended more than once to accept any favored blade, hence my continued need to abstain from what I would choose, aside from pointing out strategy and numbers. I have pointed out some of what I am familiar with.
Cheers
