If you’re a boat owner, you’ve probably heard that bottom paint is a must—but how often should you actually repaint your boat’s hull? The answer depends on a few key factors, but one thing is certain: regular bottom painting is essential for performance, protection, and long-term savings.

What Is Bottom Paint, and Why Does It Matter?
Bottom paint, also known as antifouling paint, is a protective coating applied to the hull of your boat below the waterline. It’s designed to prevent marine growth like algae, barnacles, and other organisms that can slow you down and damage your hull over time.
Not only does bottom paint protect your boat’s structure, but it also improves fuel efficiency, boosts performance, and saves you time on cleaning and maintenance.
So, How Often Should You Bottom Paint?
Here’s a quick guide:
🧼 1. Freshwater Boats
If your boat lives in freshwater (lakes or rivers), you may only need to bottom paint every 2–3 years. The growth is slower, and wear on the paint is typically less aggressive.
🌊 2. Saltwater Boats
Boats kept in saltwater environments typically need to be repainted every 12–18 months. Saltwater is harsher on your hull, and marine growth is more aggressive.
🛥️ 3. Type of Use & Storage
Boats in the water year-round: Annual painting is highly recommended.
Trailered or dry-stored boats: You can go longer—sometimes up to 3 years.
High-speed boats: These wear through paint faster due to water friction and may need more frequent touch-ups.
Signs It’s Time to Repaint
Even if you’re not sure when your last bottom job was, watch for these signs:
Visible growth or slime on the hull
Blistering, flaking, or bare spots in the paint
Reduced performance (slower speed or increased fuel use)
Pro Tip: Choose the Right Paint
Not all bottom paints are created equal. Consider the type (ablative vs. hard paint), your boating habits, and water conditions. Our team at Pacific Boat Services can help you select the right product for your boat and ensure a flawless application.
