Maintenance and Refit
How is the onset of osmosis detected on a GRP hull?
The early stage is usually invisible; by the time blisters appear the process has been running for a while. Early detection comes from measurement — moisture values in the laminate rise before any blister forms.
Why it works this way
Regular hull surveys are therefore the only way to catch osmosis while it is still cheap to deal with. The interval matters more than the instrument.
