Boat Fly

Boat Fly

Fly while riding a boat and control your boat's speed. Now with server-side configuration — server admins can restrict or customize features for all players.

Features

Boat Flight — Press B to toggle flight while in a boat. Your boat lifts off the water and you can ascend with the jump key.

Speed Control — Press I to increase speed, O to decrease. Speed is measured in blocks per second, with a default of 8 blocks/s. You can also use the /boatspeed <value> command to set an exact speed.

How flight and speed interact: When you toggle flight ON, your speed resets to 8 blocks/s as a safety measure (high speeds while flying can be unpredictable). After flight is on, you can still increase your speed with I/O keys or /boatspeed — just be careful at very high values. Speed control works independently when flight is off.

Note: Using this mod on servers like Hypixel that have anti-cheat will likely get you banned.

All keybinds can be changed in the Controls menu.

Server-Side Configuration (New in 7.0.0)

Install the same JAR on your server to unlock admin controls. A config file is generated at config/boatfly.json on first boot. Server admins can:

• Disable flight entirely — players cannot toggle flight
• Lock speed — prevent players from changing speed
• Set a default speed — applied to all players on join
• Set a max/min speed — cap how fast or slow players can go
• Disable specific keybinds — block the flight toggle, speed up, or speed down keys individually
• Disable the /boatspeed command

Configuration is sent to clients automatically when they connect. All defaults are permissive — if you install the mod and don't touch the config, everything works exactly like before.

If the server doesn't have the mod installed, the client works fully unrestricted (vanilla server compatibility).

Example Config: Fast Boats Only (No Flight)

{
  "flight": { "enabled": false },
  "speed": { "allowPlayerChange": true, "defaultSpeed": 12.0, "max": 30.0, "min": 5.0 },
  "keybinds": { "flightToggle": false, "speedUp": true, "speedDown": true },
  "command": { "boatspeedEnabled": true }
}

Set "max": -1 for no speed cap (the default).
