Iron or wood hull?
Were the hulls of the John Ericssons made of iron (or steel) or of wood? I see that they were compartmented, which ordinarily would mean that they were iron-hulled, but then I read that the hull armor was backed by 91 mm of wood. The question then is whether the wood backing was structural, or was it used only to reduce splintering? PKKloeppel (talk) 13:00, 14 October 2010 (UTC)
 * The hull is iron for all of the ships in this class.--Sturmvogel 66 (talk) 13:41, 14 October 2010 (UTC)
