Hi Claus

 

Have you been in contact with Christian Brant from Onsail? I answered a similar question from him yesterday.  If his questions relate to yourself please follow his advice. If you would like direct advice from myself contact me directly at [email protected]

 

Osmosis is not a problem with the internal structure of the Areo. The boat uses an epoxy resin matrix and this is resistant to Osmosis. The gelcoat however is polyester based and if a damp object (wet rudder bag) is in direct contact with the gelcoat in a poorly ventilated environment then Osmosis may occur. For this reason I recommend that boats are not stored outside with under-covers on, padded foil / spar bags, unused under-covers are not stored for long periods of time in the boat. Personally I try to leave air gaps under these items to allow air circulation.

 

A fun problem I had earlier this year was when I left a note pad under the cover for a few months. The pad became saturated with rain water as I had stupidly left the boat stored bow down. When I returned the ink from the Biro has leached out of the pad and into the gelcoat on the foredeck. I could then read a 3 month old grocery shopping list when on Starboard tack up wind. It rubbed off with a bit of compound and elbow grease.

 

Best regards
