Why green timber is a poor warship material

What is the worst wood someone could use to build a warship?

He identifies unseasoned green timber as the core problem because a ship built from it would rot very quickly.

The answer reframes the question from a contest between named woods to the condition of the timber when it enters the yard. Fresh, unseasoned green wood retains moisture and is unsuitable for a durable hull. Even otherwise usable timber becomes a serious liability when a builder rushes it into a ship before seasoning. Wooden-warship programs depended on stored timber and patient preparation as well as access to forests.
