Proper bottom painting is more than just a cosmetic upgrade; it is a vital component of boat maintenance, protecting your vessel from the harsh realities of marine environments. At Around the Sound Fiberglass Repair, we leverage over 30 years of expertise to provide industry-leading bottom painting services, ensuring your boat performs at its best while minimizing long-term maintenance costs.
In the Pacific Northwest, where freshwater lakes and coastal waters shape the boating experience, a boat’s hull is constantly exposed to environmental elements. Over time, algae, mineral deposits, and seasonal bottom stains reducing efficiency which could potentially cause structural damage. If left unchecked, these contaminants can harden into layers of marine growth, increasing drag, reducing fuel efficiency, and accelerating gel footwear.
Many boat owners assume bottom painting is unnecessary—especially for freshwater boats. However, failing to properly protect the hull can lead to costly maintenance, unexpected downtime, and premature deterioration.
The Consequences of Skipping Bottom Painting
A smooth, well-protected hull minimizes resistance, improves fuel efficiency, and preserves the boat’s structural integrity. When left untreated, marine buildup isn’t just a cosmetic issue—it actively degrades performance and can lead to long-term damage.
1. Increased Drag & Reduced Fuel Efficiency
Even a thin layer of biofilm or algae creates drag, forcing the engine to work harder. Studies have shown that marine growth can increase hull drag by 30% or more, leading to higher fuel consumption and reduced top speed.
Subsequently, wake boats and ski boats, where a smooth hull is crucial for wake formation and maneuverability, even minor marine buildup can negatively impact performance.
2. Accelerated Gelcoat & Fiberglass Damage
A lot of boat owners don't realize that gel coat is the protective barrier between the water and the fiberglass structure. Fiberglass is the material underneath the gel coat. When marine growth accumulates, it traps moisture against the hull, increasing the risk of:
Oxidation and fading in sun-exposed areas
Blistering due to prolonged water absorption
Structural weakening, which can lead to fiberglass damage
A neglected hull in Lake Washington, Lake Union, or anywhere in the Puget Sound region can develop gel coat deterioration in just one season, especially if the boat remains in the water for extended periods.
3. Higher Maintenance Costs & Labor-Intensive Cleaning
Removing marine buildup is time-consuming and expensive Without anti-fouling bottom paint. Boats that sit docked for months without protection often require:
Pressure washing, scraping, or multi-stage acid treatments to remove hardened growth
Extensive sanding, which can wear down the gel coat over time
More frequent haul-outs and costly hull restoration work
Even boats stored on lifts or trailers are susceptible to staining, oxidation, and surface deterioration from airborne contaminants, making regular protective coatings essential.
The Role of Anti-Fouling Paint in Bottom Protection
Bottom painting isn’t just for saltwater boats—freshwater vessels also benefit greatly from anti-fouling coatings. These specialized paints contain biocides that prevent marine organisms from sticking to the hull, helping to preserve the gel coat and reducing the need for frequent cleanings.
At Around the Sound Fiberglass Repair, we customize our bottom painting services to ensure each boat receives the best protection based on usage and storage conditions.
Selecting the Correct Bottom Paint for you Boat.
Not all boats require the same type of bottom paint. We consider several factors, including:
Freshwater vs. Saltwater Use – Boats in Lake Washington, Lake Sammamish, or Puget Sound face different challenges and require tailored solutions.
Seasonal vs. Year-Round Use – Boats that remain in the water year-round benefit from multi-season bottom paints for long-lasting protection.
Performance Needs – High-performance boats like ski boa wake boats require coatings that minimize friction while preventing fouling.

Even coverage, with extra protection in high-wear areas
Final Inspection & Detailing
Ensures flawless application and optimal performance before relaunch
Maintaining Your Bottom Paint for Maximum Longevity:
Regular maintenance is key to long-lasting protection, even with a professional bottom paint job. I remember one client neglected to get hauled a few years ago, and when he finally did haul out at North Lake Marina, he discovered he had over one thousand blisters on the bottom of the hull. Therefore, at Around the Sound Fiberglass, we recommend:
1. Regular Hull Inspections
We recommend annual inspections to check for paint wear, peeling, or thinning.
Boats that stay in the water year-round should be checked by a diver every 3–6 months for optimal performance.
2. Routine Hull Cleaning
Light cleaning prevents early-stage fouling and extends paint life.
Avoid abrasive cleaning methods, as they can strip protective coatings.
3. Repainting Cycles
Single-season boats: Repaint every 1–2 years.
Year-round boats: Repaint every 12–18 months for maximum protection.
