Keel

The keel is a core boat part, used in shipbuilding to make boats for Sailing. Keels are only used in making skiffs and sloops - a raft of any type does not have a keel. They are built at the Shipyard by interacting with the boat schematics board.

Keels are made of metal and affect the ship's armour and hitpoints, with higher-tier metals giving the ship more of each. For each 100 armour, there is one flat armour provided to the boat, and this can make the boat effectively invulnerable against certain enemies.

An adamant keel or higher is required to navigate the crystal flecked waters off the coast of Tirannwn.

Skiffs and sloops all have slightly different materials used for their keels, but each tier follows the same basic formula. Across all shipbuilding, each kind of log always corresponds to a particular kind of nail. Regular logs correspond to bronze nails, up to rosewood logs with dragon nails. Large Keel Parts are made at the same smithing anvil upon which standard keel parts are made.

Stat wise, the armour provided by the keel at a specific tier is the same for both skiff and sloop, the health it provides varies between boat types.

Keels provide flat armour to boats, allowing for reduction of damage dealt by enemies. Higher tier keels provide greater levels of damage reduction.
