The wreck that could settle ancient galley design

Which undiscovered wreck would most advance naval or maritime history?

A well-preserved ancient war galley in the Black Sea, with Surcouf as another major target.

A Greek or Roman war galley preserved below the Black Sea's oxygenated layer could provide direct evidence of its rowing arrangement. In particular, a quinquereme could help distinguish competing explanations involving banks of oars, rowers per oar or another grouping. Dating its timber could also establish when the trees used in construction were felled. Finding such a wreck during eventual clearance of mines and lost drones is raised as a possibility, not an expectation. Surcouf is then named as another wreck the panel would like to locate.
