So, new ships are ordered and will be delivered… eventually. Meanwhile, why don’t you try some 3D modelling yourself? I hereby publish all my game models under CC0 (do what you want) license. It’s really easy to start:

1) Download Blender

2) Download SeaCraft models.

3) Have fun!

If you wish, you are all more than welcome to send back any of your work to be included in upcoming versions of SeaCraft! If it is of any reassurance, I never did any 3D modeling before I did this, so if you have any free time and want to sail in your own ship type or design empire cities and vegetation – it’s your chance! Of course you are free to keep your models with full ownership privileges. :)
