Yup. In order to play SOG on a tabletop and have the ships move to the scale on the movement cards, the ships would have to be about 3/4 in long. The unreleased game "Captain's Sea" has an interesting take on movement. The idea is that the ships move relative to each other. If both ships are on the same tack and are chasing each other, the ships don't move relative to each other unless one ship is faster than the other. Then it would move the difference in speed between the two and the other ship would not move at all. I bet it will be hard to actually implement a movement metric like that, but you never know. Some wag might just figure out an easy way to do it.
