This bug is very complicated, but in short, I will list what it does. This glitch makes you in a boat server-side, but not client-side. Its side effects include but are certainly not limited to, the ability to make ghost blocks on certain servers, the ability to place blocks behind yourself while in a boat, the ability to float in mid-air, and the ability to increase your attack range by a few blocks.
As the videos showcasing the bug were too big for file limit, I uploaded them on youtube as unlisted videos
To recreate:
1. Join a multiplayer Minecraft server on the affected versions
2. Craft and place a boat on the ground
3. Rapidly right-click (you might need an auto clicker)
4. You are now in a boat server-side, but not client-side

Hmm, might be related to MC-208428
Resolving as a duplicate of MC-205477.
However please note that technically this bug report is invalid since you've reported multiple bugs at once and are using a modded server.
I'm sorry, I didn't realize there was another bug report that I duplicated, I searched and couldn't find one. I also wasn't playing on a modded server, it was a server with a datapack, and the datapack doesn't affect anything to do boats, or entities as a whole. I also did not realize this counted as multiple bugs, since they're just things that can be exploited from one bug.
I'm sorry if this was already reported, I searched and could not find a duplicate
