Follow-up: I didn't think of it at the time of posting this forum, but this same thought applies to ALL creators who sell objects on Kitely Market (so I went back and changed the title of the forum).
If the object is a home, building, piece of furniture, automobile or other item where physics can affect item performance, the creator really should list the compatible physics engine(s). This concept isn't just limited to ships. Recently there was a rather lengthy discussion on the forums regarding a Castle because it was compatible with only one physics engine and someone had bought it for use on a different engine. Fortunately the builder was able to correct the matter, but having this listed on Kitely Market would have saved the buyer some hassle.
Come to think of it, wouldn't it be good if Kitely Market added a required field:
Which physics engine(s) work with this product (check one or more): ODE Bullet Ubode All NA
That would be helpful. : )
