Description

Blue Ice is Minecraft's slipperiest solid block and the fastest surface for boat travel. Players can craft one Blue Ice from nine Packed Ice blocks in a 3×3 grid, so one crafted block ultimately represents 81 regular Ice blocks. Blue Ice also generates naturally near the bottoms of icebergs in frozen ocean biomes and in some snowy village houses. A pickaxe enchanted with Silk Touch is required to collect Blue Ice; breaking Blue Ice without Silk Touch drops nothing. Unlike regular Ice, Blue Ice does not melt near bright light sources.

Blue Ice lets a boat reach about 72.7 blocks per second on a straight, level track, making Blue Ice valuable for long Nether highways and transport links between distant bases. A Nether route multiplies the benefit because one block travelled in the Nether corresponds to eight blocks in the Overworld. Builders usually place Blue Ice only under the boat's path and add guardrails or walls to prevent collisions. Blue Ice also works as a compact basalt-generator component when flowing lava touches Blue Ice beside soul soil, giving technical players a second practical use beyond transport.

Build guide

How to build a fast Blue Ice boat road

  1. 1

    Craft or mine Blue Ice

    Craft each Blue Ice block from 9 Packed Ice, or mine naturally generated Blue Ice with a Silk Touch pickaxe.

  2. 2

    Lay a straight track

    Place a narrow, level strip of Blue Ice along the route; straight sections preserve the boat's high speed.

  3. 3

    Add side barriers

    Build low walls or guardrails beside the Blue Ice so the boat cannot slide off the track or strike nearby terrain.

  4. 4

    Launch the boat

    Place a boat on the Blue Ice, enter it, and accelerate carefully before turns or junctions.

Nether distance

One block travelled in the Nether corresponds to eight blocks in the Overworld, so Nether Blue Ice roads provide the largest distance saving.
