How to Prevent Rust on a Boat
Rust requires moisture to form, so it’s no surprise that boats get rusty being in and surrounded by water, especially saltwater, which speeds up the oxidation process.
Of course rust can do some serious damage to a boat, especially if left untreated. There are many ways to treat rust on a boat, as well as to prevent it altogether, so that your vessel doesn’t end up like the dilapidated boat in the picture above. Here are some quick tips on ways to prevent rust on a boat.
Clean Your Boat Regularly
Pretty obvious, but washing your boat regularly and keeping it clean is the most straightforward way to prevent rust. Clean your boat after every use and dry it thoroughly to keep it from rusting. Washing regularly is an important part of overall boat maintenance, so you should be doing this anyway. Use fresh water and a mild cleaner after each use, then dry any and all surfaces, especially the metal ones.
Get a Boat Cover
Covers protect your boat from exposure to elements like rain, which of course can lead to the formation of rust. Get a quality cover for your boat, made of breathable material to prevent moisture buildup and protect it from sun damage whenever it’s not in use.
Use Rust Prevention Products
Check your boat regularly for signs of rust to prevent it from spreading. Regular inspections are recommended to identify potential problem areas vulnerable to corrosion, which can spread quickly. If you find any rust stains, use a good rust remover to attack it before it spreads. To prevent rust from happening at all, get a quality rust stopper spray, which provides a protective long-lasting coating for exposed metals.
Use Corrosion Inhibitor
Beyond just rust prevention, there are products available to protect your boat from all kinds of corrosion. A corrosion inhibitor protects metal surfaces, as well as electrical connections, engine components and more. This type of product seals out moisture, and provides protection from salt spray as well as rust.
Get a Dehumidifier
Humidity creates moisture, the leading cause of rust. A dehumidifier is exactly what it sounds like, and it’s an effective means of protecting your boat from rust, as well as mold and mildew. Dehumidifiers are useful for eliminating excess moisture inside a boat while it’s on the water, as well as in its storage area.
Outboard Corrosion Prevention
Besides protecting your boat from corrosion, you’ll also want to protect your outboard motors if your boat has any. For starters, anodes on an outboard exist for the sole purpose of absorbing corrosive elements in the water, which is why they’re commonly referred to as “sacrificial anodes.” These metal components are typically made of zinc and act as the first line of defense to protecting your outboard motor from corrosion.
