I did place all those ship parts but I didn't notice the encounter showing the player. Maybe I missed something.

That might be a gamebreaking bug, banado is waiting to hear back on the support ticket to upload the latest build.
When you place the ship parts, you need to type in the name of the ship and then hit enter to save it. Then you should be able to open the gallery and hit refresh where it will popup (not sure if this is fixed or not, may have something to do with the loading/saving scripts pointing to the wrong folder), in order to encounter opposing ships you need to sail for some distance first and then the initial loading screen when clicking the battle button should give you a carousel of the different ships available and then you can select the logic after that. Due to time, we just opened up all the preset ships we had made spawn tables for along with the logic that we experimented with.
