We will never know for sure because of the fire which destroyed the CSN HQ ,but Secretary Mallory is believed to have obtained plans and specifications for HMS Warrior, certainly La Gloire, and the British floating batteries of the Erebus class, which were sea going, among others from Europe.
Well, HMS Terror sailed across the Atlantic, admittedly with an escort, but she did sail.
The Volcano class, unlike their predecessors and the French boats, were intend to proceed independantly , ie , not being towed, to their destinations, Like Warrior ,they had iron hulls. The gundecks were no lower than most sailing warships at the time, and higher than others. Being broad beamed they were steady gun platforms, with only a slow roll. Holding up well to the sailing rig in most conditions, they like most broad beam short length ship before and after were prone to being slowed by a head sea, but because of the high freeboard to the top of the bulwarks remained remarkably dry.
LOl. That last was one of 12 designs submitted from constructors all over the country, in fact that is the Admiralty Constuctors draft. When it came to making the choice for what became Warrior class, the board had already decided it was to be built of iron, and to be fast enough to both out steam and out sail La Gloire.Their profile looks a lot like New Ironsides. Probably just solving similar problems in similar ways, but I'll now want to check William H. Roberts' book on NI to see if there was any direct influence (i.e., that NI's design was influenced by them)...
Wait, I just re-read your post; that's not Terror itself... It's early and I'm not through my first cup of coffee yet...
Somewhere I have a photo of Terror at Bermuda, I will try to dig it out.Do you have an image of Terror or one of her sisters? All I can find on the web is this small image:
