Dry Rot Repair

Rate this post

Many people don’t realize that fiberglass boats are not always constructed of all fiberglass. Most boats have a superstructure that is constructed of wood and then fiber glassed. Other boats have transoms and stringers constructed of wood for additional support where needed. If not properly constructed and maintained, dry rot problems may exist.

Dry Rot is a fungus that arises from wet wood. It only needs a small amount of water to gain a foothold and send out rhizomorphic runners in search of more moisture. It thrives in poorly ventilated areas, grows in temperatures above 40º Fahrenheit, and literally eats up the cellulose of its host, destroying the wood in the process. Unless stopped, the fungus can spread very quickly, causing the condition commonly referred to as “dry rot”.
