Hull Inspection Before Peak Season

Summer on the Costa del Sol is unforgiving. With rising temperatures and higher water salinity during the warmer months, your boat’s hull faces its toughest test of the year. Many owners make the mistake of waiting until a serious breakdown occurs during their holidays; however, performing a hull inspection before the high season is the best investment to avoid being stranded when you most want to sail.

How do you know if your boat is ready to hit the water? Here are the 5 warning signs you shouldn’t ignore.

1. Appearance of blisters or small bubbles

If you notice small blisters under the gelcoat while cleaning the hull, it is a clear sign of osmosis. This process occurs when moisture penetrates the hull laminate, causing internal chemical degradation. Do not ignore it: the sooner it is detected, the simpler and more economical it is to fix, preventing the problem from affecting the structural integrity of the fiberglass in the long term.

2. Loss of speed and increased fuel consumption

Do you feel like the boat isn’t performing as well as it did last year, or have you noticed it consuming more fuel to reach the same speed? It is highly likely that your hull is accumulating an excessive layer of barnacles or that the antifouling has completely lost its protective properties, creating unnecessary friction against the hull.

3. Cracks or “spider cracks” in the gelcoat

The passage of time, minor bumps against the dock, or structural fatigue cause fissures in the gelcoat. Although they may seem like a purely aesthetic issue at first, these cracks act as a gateway for water to penetrate the inner fiberglass layers, potentially causing severe delamination.

4. Unusual vibrations or noises while sailing

If you notice vibrations that weren’t there before when accelerating, it isn’t always an engine problem. Sometimes, the cause lies in a misalignment of external elements or damage to the hull structure and accessory mounts. A professional technical inspection can rule out structural damage before the issue turns into a costly repair.

5. Worn (or missing) sacrificial anodes

Anodes are designed to corrode in order to protect your boat’s metal parts. If you check your hull and notice they are completely worn down, or worse, completely missing, the risk of galvanic corrosion on your engine, shaft, or propeller is extremely high. This is the most affordable maintenance task, yet it provides the most protection for your investment.
