Interesting, and raises a few questions Dobbs. How easy is it to use in a close combat situation where several ships obstruct the line of the template? It is hard enough to deal with overlapping cards in these situations, and this seems to be the point at which ships get nudged out of place in our games. However it is an interesting idea and well worth experimenting with if you are playing a simple one on one game.
As Jonas says things could get complicated with more ships in play.
