MOVES : cm or something else ?

The way the models should be moved could be done with a ruler and a list of speeds in cm.

I decided against this because

1. I dont want lots of rulers and tapemaeasure on the tabletop.
2. Fussing about mm should not be an aspect of the game.
3. A template for turning should include a straight course measurement.
4. Moving should be in arbitrary 'ship lengths' based on Olympia, a 3.

In one move segment, if the ship can move, it will cover a standard ship length and this will be a resaonable distance on the table. Thus in one full turn a ship could charge 5 ship lengths across the table which would be something like 75cm. That is enough to give some dynamism to the game and stay away from nudging things around at snail's pace.
