Q: Any reason for this or the order doesn't matter at all?
A: the order doesn't matter at all. Both horizontal and vertical must be checked. A ship can \
not be placed if there is not enough horizontal nor vertical space.
The method, as it is now, can be divided in two smaller methods (one for vertical and one for \
horizontal) reading two times the matrix. Or it can be done in one pass with an additional \
column(or row) array. The second way should be faster.

horizontal and vertical availability, which -- once again -- could also be split into smaller \
methods. One for each case.
You also decided to check horizontal availability first. Any reason for this or the order \
doesn't matter at all?
How the AI would know in which direction it should place the new ship?</pre>
