Is wet storage harmful for a boat?

Boating enthusiasts often wonder whether storing their boats in a wet environment is harmful or not. While some people may believe that keeping a boat in water is beneficial, others argue that it can lead to severe damage. In this article, we will explore the potential harm of wet storage and how to prevent any damages.

One of the main concerns with storing a boat in water is the possibility of osmosis. Osmosis is the absorption of water by fiberglass or other materials that make up a boat hull. Over time, osmosis can damage the structural integrity of a boat, leaving it vulnerable to leaks and other issues. The process is accelerated when boats are left in the water for longer periods.

Furthermore, when the boat is stored in water, it is exposed to marine growths such as barnacles, algae, and other organisms that cling onto the hull. These organisms can cause damage to the hull, leading to weakness, erosion, and reduced performance. Additionally, a boat kept underwater can develop electrical and mechanical issues due to exposure to saltwater and other corrosive substances.

To prevent damage to your boat from wet storage, regular maintenance is the key. It is essential to clean your boat regularly and use anti-fouling paint to discourage marine growth. You should also regularly inspect the hull for signs of wear and tear, including cracks, blistering or laminate separation, which could lead to osmosis.

Another way to prevent damage is by using boat lifts, dry stacks, and trailer storage. These options allow the boat to be dry and free from any marine growths or corrosion. Boat lifts or dry storage also provide added protection from rough water, reducing the risk of damage from collisions or storms.

Storing a boat in water for an extended period can be detrimental to its integrity, performance, and structure. While some boaters may find wet storage convenient, it may shorten the lifespan of their boat. Preventing damage from wet storage through regular maintenance and the use of dry storage methods is crucial in preserving the boat’s value and performance. Remember to perform routine checks to catch any potential issues before they become a significant problem.
