The cool way to travel fast, now in Minecraft™ Java Edition!

Summary

Lightspeed boat is originally a bug feature in Bedrock Edition, where boats receives no friction when on slabs. This allows for accelerating boats to enourmously high speeds using flowing water. (Note: It is now half-fixed in Bedrock Edition)

This mod brings the feature to Java Edition. Enjoy cool automatable fast travel systems!

The figure above is an available design for accelerating boats. Read more about Lightspeed Boat on Minecraft Wiki.

WARNING: This mod must be present on both server and client, otherwise some server-client desync can occur.

Note: By default, the mod has a protective measure that prevent the speed from exceeding 72.73m/s (the blue ice speed).

Details

Here are the mechanical details of the mod.

The boat will enter lightspeed state, if it has a velocity greater than lightspeedThershold 2.4 (in m/s), and one of the following is satisfied:

• The boat's Y coord substracted by the floor of itself is between slabHeightMin 0.4999 and slabHeightMax 0.5241. The boat must be either IN_WATER or ON_LAND. The block the boat is on cannot be Water or Bubble Column. (This requires the boat to be on a slab)
• The boat's bounding box's maxY is integer, and the Y velocity of the boat is near zero. (This requires the use of Soul Sand Bubble Columns and Trapdoors)

If requireLevitating is enabled, the first condition will be disabled.

When under lightspeed state:

• The drag (horizontal velocity decay) will be constantly lightspeedDrag 0, unless the speed exceeds maxLightspeed 72.73.
• If allowPlayerDrive is false, the player will not be able to drive the boat, but can still turn it.
• If allowPlayerTurn is false, the player will not be able to turn the boat.

Values can be customized by editing the config/lightspeedboat-common.json file.
