I have only read the Edith Grossmann translation but found it quite good. I've read somewhere that it is not the most comical translation, but strives to be correct in a sense. Also, all the "old" words are described in footnotes, for those of us who are not experts on medieval litterature or 1600s ship concepts.

I read the first 100 or so pages of the Starkie translation, but lost it and later read I believe the Cohen translation in its entirety. I thought the Starkie version was clearly superior for the part I read.
