€20,000 to maintain a replica ship?

[Giannis K. Hoplite]

It so happens that the captain of this ship is my neighbour and i have asked him about the maintainance costs of this ship and of Olympias, that to me seemed extraordinary, and he explained to me that it is the construction method of these ships that make their repairs very difficult.
Contrary to medern ship building, the ancient boats were constructed hull first, with a system of pegs that fitted the wooden planks together. The sceleton was added after the hull was complete. The problem is that if one plank needs replacement, one has to dismantle all the planks above it, replace it, and put all the timber back again. Does 20.000 seem still too much?
The ancient harbours would have (he calculated about 8) men working every day on this exact job on every ship that needed repair, in constant basis.
