Boats are important investments, so yes, they should be protected from the elements. Just as you would not leave your convertible top car open in the rain, you should always make sure that your boat is covered when it rains. Leaving your boat in the rain can damage several functions of the vessel.
Certainly, the boat spends a great deal of time in the water, or it may be marked as water-resistant, don’t be tempted to think the rain cannot affect it. The materials the boat is made with can withstand certain amounts of water from divers or splashes from the lake or river. However, with the rain, there is an increased volume of water stomping everywhere.
Does rain damage boats?
While it sounds ironic that something made to be in water can be damaged by water, if left unprotected, rain, snow, and sleet can damage your vessel. In boats left under the rain, it is not uncommon to find that their interiors get worn or damaged very quickly. Some damages rain could cause to the interiors of your boat are:
Damage to interior aesthetics
One reason you chose that particular boat is how cool it looks; the vinyl, the leather chair, the paint, and all. They all matter. When water gets in contact with the gel coats, or the resins, it could spark a reaction that leads to the formation of blisters and the ultimate breaking of the paints.
Persistent rain and sun penetration can cause the vinyl of your boat to fade out losing its pretty color and appearance. Also if you have some parts that are metallic or exposed, continuous rain might also initiate the rusting. In the end, your boat is not as pretty as it used to be and its value is sliding much faster.
Rotting of some parts
Think of it, the interior of your boat is made of several materials such as fiberglass which is padded with wood and foam. If water gets into these fittings, the wood floor, or seat bottoms it encourages the growth of mildew and initiates a rotting process. This is especially worse if you have a completely wooden boat.
We all know that once a part rots, it loses fitting and that makes your boat less stable. The saddest part of this is that rotting is not easily noticed till it has gone very far and maybe well beyond remedy.
Damage to the engine

Just as water can cause damages to any electronic and motor engine, the engine of the boat is not immune to water damages. You would find that certain controls become stiffer, some gauges no longer working and some wires get corroded. Although these might be repairable at a very high cost, they could have been avoided.
Extended cleanup time
Leaving your boat uncovered during the rain creates an extra clean-up task for you. After the rain, you would have to scoop out the water from the boat and thoroughly get out the water. Cleaning up is not an easy task and can take a lot of time especially if you need to go out quickly.
