The first internal version of ocean battles had this kind of destruction, but the performance is just terrible because there are soo many parts of the shi.
Just a small explanation for better understanding.
The ship is build from many objects -> The wood planks, sails, other wood parts, ...
To run smoothly, all those parts have to be combined to one object, because it's better for the gpu to render 1 large object instead of 1000 small ones, you know?
If I break one part of the ship, I have to reactivate all smaller parts of the ship to see the hole and destroy some of the small parts.
Here is the problem. I can let all parts as single small objects, but the gpu will die, or I can recombine all small objects again, but in that case the cpu will die...
I hope this helps to understand why there is no destruction for ships.
But I love the bunny idea! I will release the next update a few days before easter with the bunnies.
