Water entering your yacht during washing is never something to ignore. While the cause may sometimes appear to be a small leak, damaged or deteriorated sealant around fittings can allow water to penetrate areas that should remain completely watertight.
During a recent yacht maintenance job in Limassol Marina, our team identified a problem with the sealant between the yacht’s hull and the metal fittings. The existing sealant had dried out, cracked and deteriorated over time, allowing water to enter the yacht during washing.
This is a good example of why regular yacht maintenance and inspection are important for protecting your boat and preventing small issues from becoming more serious problems.
Why Does Yacht Sealant Deteriorate?
Marine sealants are constantly exposed to demanding conditions.
Salt, water, strong UV exposure, high temperatures, humidity and regular washing can gradually affect the flexibility and adhesion of sealant.
Over time, you may notice:
- Cracks in the sealant
- Gaps between the sealant and fitting
- Peeling or separation
- Dry or brittle material
- Water appearing inside the yacht
When the sealant can no longer provide a reliable barrier, water can find its way through even very small gaps.
For yacht based in Cyprus, regular inspection is particularly important due to the strong Mediterranean sun and constant exposure to salt water.
Water Ingress Can Become a Bigger Problem
A small amount of water entering the yacht may seem insignificant, but continued water ingress can potentially affect surrounding materials and components.
Depending on where the leak occurs, water can reach:
- Interior surfaces
- Electrical components
- Insulation
- Wooden structures
- Metal fittings
- Other areas of the yacht
Our Yacht Sealant Replacement Process
1.Removing the Old Sealant
The deteriorated sealant was carefully removed from the joint between the hull and metal fitting. Simply applying new sealant over damaged material is not a reliable long-term solution.
2.Cleaning & Preparing the Surface
Once the old sealant was removed, the area was thoroughly cleaned and prepared. Proper surface preparation is essential for achieving good adhesion and creating a reliable seal.
3.Applying New Marine Sealant
A suitable marine-grade sealant was carefully applied to the joint. The objective was to restore a clean, flexible and watertight seal between the yacht’s hull and the metal fitting.
Final Inspection
The completed area was checked to ensure that the new sealant was properly applied and that the joint was fully sealed.
How to Prevent Water Ingress on Your Yacht?
Regular visual inspections can help you identify potential problems before they become serious.
When cleaning or inspecting your yacht, look closely at:
- Deck fittings
- Metal-to-hull joints
- Windows and hatches
- Through-hull fittings
- Railings and hardware
- Areas where different materials meet
If you notice cracked, separated or deteriorated sealant, it is worth arranging a professional inspection.
Don’t wait until water starts appearing inside the yacht.
