Copper Sheeting

Within the last 300 years, a new Technology has been developed and deployed among Shipbuilders known simply as Copper sheeting. These thin Copper sheets protect the wooden hull of a ship from Rot and decay, especially the degradation of the Hull from the Toredo Worm that thrives in the Warmer ocean waters of Evermyst.
Thin metal Sheets of Copper are forged to the thickness that they can be pliable and are bent around the Exterior of a ship's hull and sealed into place. Each lair is sealed at the edges with pine tar and overlapped from the Keel up to a distance of 6-12 inches above the waterline. Placing these copper sheets on ship hull exterior makes the need to careen their hull easier and less often as sea life such as Barnacles and Toredo worms do not adhere or start to grow on the copper sheeting.
Careening on a Hull without copper sheeting needs to be done every 4-6 months to avoid rot and prevent loss of sipe speed and performance while a Hull with copper sheeting can go as long as one to two years before this careening needs to be done. Other materials can be commonly used but none are as effective as copper sheeting. Lead plates could be effective but they cause a chemical reaction to the ship's bolts adhering the planks of the hull to the ribs. Zinc Strips or plates have also been used but to lesser effectiveness.

Manufacturing

Copper needs to be smelted and then poured into thin slabs that are rolled into thin sheets.

Access & Availability

Copper sheeting is usually only available for the Naval Military and more wealthy shipbuilders and shipyards.

Complexity

The Technology is not overly complicated it just can be cost restrcitive.

Discovery

First used By the Elves it was believed to just be the decorative desires of Elven Shipbuilders but soon was taken on by Human and Dwarven shibuilders
