Worse Swimming
by Funk Planet
Worse Swimming changes how swimming and wading feel by altering the movement calculation that Minecraft applies in water and on land.
What it does
Minecraft's movement code treats swimming too generously, because status effects such as Slowness barely reduce swim speed and friction builds up velocity quickly. The mod inserts two extra friction terms into the swimming calculation, so a player fully submerged in water is slowed by the mod's values, while shallow wading is slowed on its own track.
Out of the box, wading is set noticeably slower than swimming, and both speeds can be tuned in the configuration. The mod runs on the server alone, so players join without installing anything. Files are published for Fabric only, across two release versions, 1.20.1 and 1.21, with 1.0.0-1.21-1 as the latest file. The source code is public and the project is released under the MIT License, so it is open source.
Key features
Swimming friction
A friction component applied to swimming stops velocity from building up as quickly as it does in vanilla.
Wading friction
A separate component handles movement in shallow water, so wading is not governed by the swimming values.
Adjustable speeds
Both the swimming and wading values can be changed in the configuration file to suit a server.
Effects that slow swimming
Slowness and similar effects take visible effect on swimming speed, which vanilla code does not provide.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Server-side difficulty
Server owners who want swimming to demand more time can install the mod on the server, with no change needed on player machines.
Who it’s for: Server owners and players who find vanilla swimming too fast or want water travel to matter more in survival and adventure play.

What the author says
Minecraft's movement code is complicated and has some problems. One of these problems is that because of the way swimming is implemented, effects like Slowness and Speed barely affect swim speed at all.
