<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I see here that you're testing for both 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>

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.</pre>

The code is OK, I'm not asking you to change it. I'm just pointing out that I prefer code that's easy to read, and thus maintain, than optimized code whose performance improvements are not significant.</pre>

Also, it serves me to split a big patch into smaller pieces.
How it is done:
* Pass the parameter allow adjacent ships also to the BattleField.
* Implement a bool canAddShipOfSize(size). When a ship of size size can not be placed, then the AI or the player should start again (what I'm working on) or an Undo.
* Implement a clear() to be able to start again
* In the battleField also add another hidden board with the cells having only two status (free, busy) to be able to know the availability of the cells. It is easier for me in this way than the other way (sending a signal to clear the ship borders when the shooting starts).
