What is the purpose of the Blue dotted Lines ?
can the police use these lines as a move from South 152 to North 173
also North 66 to South 98 and vice versa
it would make sense for these lines not to be there otherwise
I also think it makes sense for the Blue INVESTIGATOR to use his special Boat ability if his crossing is connected to a blue circle. (the blue circles being safe areas of water that a boat is moored at.
Incorrect on both counts.
The purpose of the blue dotted lines is to denote the boundary of the body of water (along with the black dotted lines).
The blue investigator can use his special boat ability to move from one crossing on the boundary of a given body of water to another.
Boats and lanterns are conceptually the same, the only difference being water versus land. In both cases the only restriction is that you can't cross a dotted line when performing the move. Does that make sense?
