Black Rock Flashback?

Lost Season 5
Spoilers
Thanks to ODI for this latest bit of scoop! It looks like the producers of Lost are on the hunt for two ships (one black) – both of which need to be seaworthy.

The main one they wanted was a big black ominous looking ship, but the ship company didn’t have anything that was even remotely similar to what they described. However, they booked another ship and it’s going to be a chase ship which goes after the big black one.

The chase ship is the oldest ship in the marina and it looks like it’s from the 1500’s. Do you know why they would want boats that looked to be several hundred years old?
