Whether Grace Dieu is worth raising

Does enough of Grace Dieu survive to make raising her worthwhile?

Probably yes for naval-history study, though marine-archaeology preservation concerns could change that assessment.

The answer is yes from the perspective of a naval historian, because recovering and preserving the ship would open valuable study opportunities. It also carries an important caveat: a marine archaeologist might judge the preservation tradeoffs differently, so the historical appeal is not the only consideration.
