No surprise there. Read up on the evolution of iron clads, armored cruisers, and wooden walls. Eventually, warships stopped framing in wood and reserved precious lumber for planking. Iron and steel replaced wooden frames. Later still, Sheets of steel and iron sheathed the entire exterior. Sure is good to be from Boston to see 'Ole Ironsides' (USS Constitution). smile.gif Very interesting none the less.

I believe that the Tumlaren is built with every third frame made of steel. Why not ? I've also seen some nifty metal floors.

Anyway - iron/steel framing can be a pain in the butt when it gets old and starts rusting in salty conditions. A good, stout wooden frame only gets better preserved the more salt you add. Way back when, the first freights of choice for a new ship were bulk salt transports. The crews would spend lots of time in the hold shovelling salt into the space between the hull and the inner planking. When well packed with stolen salt, the ship could be used in other transports - preserved in salt for life.

The J Boat Shamrock V, is 2.5 inch wood planking over an iron frame.

old ironsides was a wooden frigate I believe and later in it's life, they clad her with iron sheet for defenses. British ships firing on her during the American revolution saw their shot bounce off her thick armor. smile.gif

In the war of 1812 while oblterating the HMS GUERRIERE the nickname was coined when a cannon ball was seen to bounce off the ~21" of live oak plank and frames.

As a ironclad, you may be thinking of the USS NEW IRONSIDES , iron over wood screw steamer built just before the civil war.

PS. On topic, most later (post 1860ish) tea clippers were composite built, wood over iron frames.This includes Sir Lancelot, Thermopylae, Cutty Sark etc.
