Crate Capacity

Crate capacity is the maximum number of crates that a ship can carry. Trade ships can carry crates (or sticky pistons) up to 0.015 * block count or sqrt(block count), whichever value is smaller. The switch occurs for ships around 4444 blocks.

A ship can detect with more sticky pistons than the maximum amount of crates it can carry, but it will not be able to carry additional crates. Ships cannot be detected with more crates than their limit.

Warships can mount half as many crates as a trade ship of the same size.
