OpenBoatUtils
OpenBoatUtils changes how boats handle on Fabric, with configurable physics for boats on 1.20.1 – 1.21.11.
What it does
Boat behavior in OpenBoatUtils is adjustable. The mod exposes settings that alter how a boat moves and responds, so players on a single-player world or a multiplayer client can tune the ride to their preference. Only the player's installed copy applies the changes, and no other side is involved.
OpenBoatUtils requires Fabric API, which must be installed alongside it on Fabric. The mod is distributed for Fabric only, and its files cover fifteen release versions 1.20.1 – 1.21.11 under the MIT License, which makes it open source. The source code, an issue tracker and a wiki are publicly linked, and the wiki describes the features in more detail.
The mod was first published in August 2023 and was last updated in June 2026. Its latest Fabric file is built for 1.21.11 and was released on 2026-06-17.
