This skill adds one unit of keel to a ship.

Each unit of hull may mount one unit of keel. For example, a 3 unit hull could mount up to 3 units of keel.

Due to the keel's heavy weight, each unit of keel added to a hull reduces the capacity by 100 units weight.

Keel protects a ship against storm damage. Ships caught in a coastal storm have the following chance of sustaining damage:

(15 - (units keel / unit hull) * 30)%

Thus a ship with at least two units of keel for each three units of hull will (under normal circumstances) be immune to damage from coastal storms.

Ships caught in open ocean storms have the following chance of sustaining damage:

(35 - (units keel / unit hull) * 30)%

Keels also protect a ship from reef damage. Reef damage to a ship is reduced by (units keel / units hull)%. A fully keeled ship will not be damaged by reefs.
