possible osmosis

[Guest]

If a grp hull has a relatively"high" water content does this mean it is a sign of future osmosis? The boat has been in the water since march.
Thanks

NO.

Moisture content is all relative. Look at www.yachtsurvey.com
for some excellent advice re blistering.

All GRP hulls take water. Is a natural process. Wait two weeks after lay up and depending the weather the moisture will be lower. If gelcoat in the underwater hull is colorless (transparent) is better.
