New New ships mod

[VanderGraaf]

So... I and my buddy were trying to create a mod which adds ships (a fast ship and a huge cargo ship) to the .16.x game.
We encountered a few issues. First of all it's impossible to enter the ship unless you are at a few pixels of distance, which makes the placing/driving mechanics very complicated. Furthermore it's impossible, unless you are in god-mode, to leave the vehicle even if you are very close to land.
Is this problem due to engine limitation/0.16 version or are we doing something wrong?
