The Tramex Skipper Plus, non-destructive moisture meter, provides a complete and safe method for detecting excess humidity in fiberglass and wooden hulls. The Skipper Plus is a pocket hygrometer, designed to locate humidity in the hulls and accessories of the boat.
Three scales for humidity detection in GRP and hardwood for salt and fresh water.
- Wide range of wood readings from 5% to 30% on a hardwood scale and from 0 to 100 on a comparative scale for fiberglass and other materials.
- Identifies the presence of osmosis in fiberglass hulls.
- Confirm if the wooden boats are dry enough for painting or varnishing.
- Track leaks on decks and bulkheads.
- The "Hold" function facilitates the recording of readings.
- Soft rubber electrodes provide direct contact without scratching.
- Audio warning tone for high humidity can be activated or deactivated.

Skipper Plus is based on the principle of measuring non-destructive impedance. Coplanar electrodes, mounted on the base of the instrument, transmit low frequency signals in the tested material and measure the variation of impedance caused by the presence of humidity. This reading is indicated on the instrument as a reading of the moisture content.

The Skipper Plus moisture meter is used for:
- Timely detection before the appearance of osmotic bubbles.
- Identification of the affected area.
- Hull monitoring during dehumidification and repair phases.
- Checking the drying of the abraded areas before recoating.
To obtain lasting finishes and resistance of hulls and wooden components, it is essential to ensure that they are well maintained and that they do not contain excess humidity.
Excess humidity can create phenomena of structural and aesthetic deterioration, both on wooden and fiberglass hulls or special composite materials.
Moisture can cause de-lamination and blistering of finishes and applied treatments.
New paints can fail prematurely if the wood on which they are applied is not sufficiently dry.
Hidden or trapped moisture can lead to mold and biological growth.
Skipper Plus can be moved to the surface of the boat to detect humidity quickly and accurately, detecting humidity non-destructively through paints and coatings on wood up to a depth of 30 mm (1,25 ").
Skipper Plus can also be used to detect leaks and trace them at the source, both above and below the bridges without damaging the surfaces and without scratching the aesthetic parts.

Il Tramex Skipper 5 is a non-destructive moisture meter, designed to accurately detect hidden moisture in the hulls, decks and superstructures of fibreglass (GRP) and wooden vessels, including those with sandwich or core structures. This instrument represents the evolution of the previous Skipper Plus model, maintaining the features appreciated by professionals in the sector and introducing significant improvements.
Main features
- Non-destructive measurement: The Skipper 5 uses dual-depth technology to detect moisture without damaging the surface being tested. This feature is especially useful for preserving the structural integrity of vessels during inspections.
- Double penetration depth: Thanks to a unique arrangement of the three electrodes, the instrument offers two levels of measurement depth:
- Superficial: up to 10 mm, ideal for assessing humidity in the outermost layers.
- Deep: up to 30 mm, useful for detecting moisture trapped in inner layers or sandwich structures.
- Three scales of measurement:
- Hardwood: provides a direct reading of the moisture content in the wood, expressed as a percentage (%MC), with a range from 5% to 30%.
- Reduced depth: comparative scale (0-100) for surface measurements on materials such as fiberglass.
- High depth: comparative scale (0-100) for deeper measurements, useful for assessing humidity in composite or sandwich structures.
- Ergonomic Design: Compact and portable, the Skipper 5 is designed to be easily used during inspections, even in confined or difficult-to-access spaces.
Practical applications
- Osmosis detection: Moisture trapped in fiberglass hulls can lead to osmosis, a phenomenon that compromises the structural integrity of the vessel. The Skipper 5 allows these problems to be identified early, allowing timely interventions.
- Check before painting or repairing: Before applying paints, resins or other coatings, it is essential to ensure that the surface is sufficiently dry. The Skipper 5 helps determine if the humidity level is adequate to proceed with the work, preventing potential defects or delamination.
- Monitoring of infiltrations: Boats are constantly exposed to water, and leaks can cause significant damage over time. Using the Skipper 5, you can precisely locate areas affected by leaks, facilitating targeted repairs.
Tips for optimal use
- Regular calibration: To ensure accurate measurements, it is advisable to periodically calibrate the instrument following the instructions provided by the manufacturer.
- Environmental conditions: Perform measurements in stable environmental conditions. Significant changes in ambient temperature or humidity may affect readings.
- Clean surfaces: Before taking a measurement, make sure the surface is clean and free from contaminants such as oils, salts or dirt, which could alter the results.
- Use of appropriate scales: Select the measurement scale that best suits the material and depth of interest. For example, to assess surface moisture in a fiberglass structure, use the reduced depth scale.
- Interpretation of the readings: Comparative scales (0-100) do not provide absolute moisture content, but they do allow you to compare different areas to each other. Use this information to identify areas with abnormal moisture levels compared to others.
Maintenance and care
- Electrode cleaning: After each use, gently clean the electrodes with a soft cloth to remove any residue.
- Food container: Store the instrument in a dry, protected place, preferably in the case provided, to avoid accidental damage.
- Replacing the battery: Monitor battery health and replace when necessary to ensure optimal performance.
