Registering a boat alone would be pretty darn cool, but what if it could have:

• Customizable animations and models
• Customizable amounts of passengers
• Boat drift (I guess this could just be .tick() + adding to boat velocity?)
• An NBT tag to change the boat texture (like vanilla)
• Boat interaction:
  • Right-click the boat with a chest:
    • Add a chest & update the boat inventory
    • Show it on the boat entity
    • Possible to have more than one chest
  • Right-click the boat with a lead:
    • Make the boat follow the lead
    • Reflect it on the boat model
    • Right-click again to untie the boat
  • Right-click with a (custom item) paddle:
    • Enable player boat controls
    • Add paddles to the boat model
  • Shift-right-click to remove stuff added to the boat (like the chests or paddles)

The inspiration for most of this suggestion came from this TerraFirmaCraft addon

Ah awesome! Hope to see it :D

i just looked into it and it seems this is possible with geckolib's recent fixes to non living entity rendering, i'll have to do this when i have time after i add part entities and some other things ect, very cool suggestion!
