Paul,

Have you seen the book "Osmosis and the Care and Repair of Glassfibre
Yachts" by Tony Staton-Bevan, 1989? It's very good, very complete.
Chapter 2 discusses various causes and examples, e.g. page 22: "Boats
kept in fresh water or warm water are likely to blister much sooner
and it is not unusual to find blistering after 12 months afloat under
either of these conditions."
Good book, good repair techniques, good pictures.

Does anyone have a clue about how long it takes for hull
blisters to form? Has anyone heard of them forming on a
new boat in less than a year? I have always suspected
they take a good long while to form, but have nothing to
back that up.

your thoughts please.
