Osmosis, also known as Gelcoat Blistering, is found in GRP boats when moisture soaks into the hull surface, collects between the glass fibre/plastic laminate and causes surface blistering of the gelcoat. Usually found below the waterline, Osmosis dramatically increases boat weight while reducing structural strength of the hull.

To achieve a lasting finish on painted or varnished wood it is essential to ensure new or stripped wood is dry and, if overpainting, that no moisture is trapped beneath existing paint.

It is also important that the weight of a racing yacht is kept to the minumum in order to maximise boat speed. Therefore, thorough drying out is essential before paint or antifouling is applied and the boat returned to the water.

The Skipper Plus Moisture Meter

The Skipper Plus non-destructive moisture meter provides a complete, safe method for detecting excess moisture in GRP and wooden boats. A pocket sized meter, the Skipper is designed to locate moisture in boat hulls and fittings.

The Skipper Plus is used for:
• Early detection before blistering appears.
• Identifying extent of affected area.
• Monitoring hull during de-humidification.
• Checking stripped areas prior to re-coating.

Benefits: Specifically designed for the needs of the Marine industry. Three ranges for detecting moisture in GRP and Hardwood for salt & freshwater. Identify the presence of Osmosis in Fibreglass Hulls Confirm if wooden boats are dry enough for painting or varnishing. Trace deck and bulkhead leaks. Soft rubber electrodes make direct contact without scratching. No Pins, No Probes, No Scratching.
