€20,000 to maintain a replica ship?

[M. Demetrius]

For longer time periods are they stored on land?

The ancients hauled them up onto shore or into a ship shed whenever they stopped for more than a night or two to keep the woodworms from eating the wood below the waterline. Sea (and land) termites, sort of. Or at least that's what I've been told.

Their ships were pulled onto shore in the Odessey, iirc, but that's not really a historical reference.
