Create Aeronautics: Boat Propellers

The add-on gives Create Aeronautics boats a propeller bearing that runs with less stress and turns at lower speed, which makes it a practical option early in a playthrough. Later boats are described as better overall, and the propeller setup does not need steam. An engine reaches only modest speed on its own, so the bearing is the main route to faster craft. Create Aeronautics is required, and the mod is published for NeoForge only, with version 0.1.1 for 1.21.1 on the alpha channel. Client and server both need it.
