although it could have been better with a less two-dimensional Maturin.

FTFY

You must admit that in the books Maturin is the most compelling and well-explored personality, and the character POB most closely identifies with (finding based solely on personal assumption, mea culpa).

I would assert that the film, as good as it is, reinforces my thesis that the golden age of sail is the least adaptable to film of any literary genre. The movie is to the books as a description of the Grand Canyon is to the actual experience.

Also they are “studding sails” and referred to colloquially as “stun’sl’s” https://en.m.wikipedia.org/wiki/Studding_sail

So there.
