Humidity control in boats is a fundamental aspect to ensure their structural integrity and prevent problems of osmosis and degradation of materials. Humidity measurement of hulls and boats allows to identify the presence of water trapped in composite materials, wood and other parts of the boat, avoiding costly repairs and maintaining high performance of the boat.
Why is it important to measure humidity in hulls?
Excessive humidity can compromise the strength and durability of boat structures. The main risks associated with high humidity include:
- Osmosis in fiberglass hulls: the phenomenon of osmosis leads to the formation of bubbles and delaminations, reducing the resistance of the hull.
- Degradation of wooden structures: Wood can absorb moisture and deteriorate rapidly, causing rot and loss of strength.
- Problems in sandwich structures: Composite cores used in modern boats can retain moisture, compromising their integrity.
- Difficulty in applying paints and resins: a high level of humidity on the treated surfaces can compromise the adhesion of protective coatings.

Humidity measurement instruments for hulls and boats
One of the most used instruments for measuring humidity of hulls and boats is the Tramex Skipper Plus, a non-destructive hygrometer designed specifically for the marine industry. This instrument offers numerous advantages, including:
- Non-invasive measurement: allows you to detect humidity without damaging surfaces.
- Three scales of measurement: suitable for different materials, such as wood, fiberglass and composite structures.
- Wide range of detection depths: allows you to detect humidity both on the surface and in deeper layers.
In addition to the Tramex Skipper Plus, the new Tramex Skipper 5 offers further improvements, such as double detection depth and increased measurement accuracy.
How to measure humidity correctly
To obtain accurate results when measuring the humidity of hulls and boats, it is important to follow some good practices:
- Check the instrument calibration before starting measurements.
- Clean the surface thoroughly to avoid interference from contaminants such as salt, oils or dirt.
- Take multiple measurements in different areas of the hull to obtain a complete assessment.
- Avoid measuring in extreme conditions of ambient temperature and humidity, which could influence the results.
- Interpreting the readings correctly using the instrument-specific scales for the material being analyzed.
Conclusions
Humidity measurement of hulls and boats is an essential activity to prevent structural damage and prolong the life of boats. Professional tools such as the Tramex Skipper Plus allow you to accurately detect moisture in materials, providing useful information for the maintenance and restoration of nautical structures. Investing in regular moisture monitoring ensures safety and optimal performance for any type of vessel.
