A bearing is a component in any machine that allows the forced
relative rotational or linear movement between two parts. They
are typically present between two parts of a machine to reduce
friction. It is very important for any machine to work under
very little friction so that it gives the optimum output and
performance.

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". Dry rot can be your boats worst enemy. Moisture causes wood to break down in composition and It generally will require professional attention. All damaged wood must be identified and replaced to maintain the structural integrity of your boat.
