The directional arrows or the grid of the board?

Even if I look for an alternative plan, I will push the original idea of arrows further before making a decision. This is an important decision that can change a lot of things, not just the way boat move around.

I must admit that if I turn to the grid, several small problems will disappear. But on the other hand, I’m going to have to redesign and introspection all the rules and remake some pieces.
