**@Da Stranger: **I can with almost certainty say that this feature will not be added by July. I am working on a lot of other features and they will take quite some time to get done. I will gladly help you add it yourself, however. If you are making something exactly like the image you are showing there are some things you do not have to worry about, such as walls between tiles or multiple height levels, which should make it easier. Is that the only form of large ship or are there others that take up more than four tiles? If there is only one type it also becomes a lot easier to add.
@rob33: Good thing it worked and I hope you understand my reasoning for why this worked when your previous solution did not
