Osmosis Impossible?

I came across this statement in a Yachtworld desription:

"The ships hull is constructed in a sandwich method: built on a core, a layer of foam and then finished by hand using a layering method with polyester and fiberglass material and afterwards the vessel has been evened out. This ensures a maintenance-free ship without risk of osmosis."

I understand cored hulls and cored decks, usually with foam or wood.

Is there a special method that this boat has used to avoid the possibility of osmosis? How?

Is there a construction (GRP) that can avoid it?

Here is the listing to reference:

1983 Van De Stadt one-off Sail Boat For Sale - www.yachtworld.com

Many thanks.

Martin
