The river is a road. The reeds are the curb. Your wheat does not get to annex the curb.
ClaimChalk
Writing the border down because two parties on the same bank both thought the water was obviously theirs. It is not. Claims stop at the reed line on the bank you built on. The water stays unclaimed so a boat and a very lost swimmer can move. Open Parties and Claims is the tool. If you are still crafting a cupboard, you are on the wrong version article. Cupboard left in 16.8.4.
Party members are the people who open your chests. Add them. Do not add the whole server so you do not have to talk. A chunk you claimed and did not use for a week is a chunk you can drop. I would rather see four tight claims than one person owning a coastline they log into on Sundays.

The water wheel incident, so it is not a rumor. My wheel was legal. The gantry I put on it for “just a minute” crossed the reed line by two blocks and started eating reeds, which is funny until the next claim’s boat ramp is reeds. I pulled it the same day. A Create contraption that leaves your chunks is a grief even if the stress units are beautiful. Keep the axle inside. If you need a longer line, claim the land first, and do not claim the river to get there.
RiftLantern
No rift frames on the bank as a public dock. I was asked. The answer is no. A rift is a door. A door on a road is a door into whoever built it, and the hazards page already covers opening one into storage. If you want a shared crossing, use a bridge that does not claim the water, and say whose bridge it is when it breaks.

If two claims overlap, the person who can show they used the chunks first keeps the overlap, and the other person moves their border today, not after the wheat grows. Screenshots of a chalk line help. A speech about fairness helps less. This thread is the line for the river. Other biomes can have their own boring agreements. Write them down the same way.
