Thoroughbred miniatures ACW vessels are just a bit on the large size for gaming but I doubt that will stop anyone from using these, especially if they have enough space.  The range is extensive and the models well-detailed with many small pieces for some ships like the Hartford making these more of a project than most.

I first encountered these when with nothing to do on a weekend in Columbia, SC, I wandered into a toy soldier convention.  It was a small but interesting gathering.  The Thoroughbred display drew my attention more than any other.  I have been slowly gathering them since then.  ‘Then’ was likely about 12 years ago.

There are a reasonable number of rule sets available for ACW ironclads.  One likely candidate is the Ironclads games originally offered by Yaquinto.   The size of the larger ships, though, make these unlikely candidates for hexagons on all but the largest game mats.

Of course, the charm of these miniatures is the careful attention to detail.  These miniatures straddle the line between display and gaming.  Since the reality of gaming is that most gamers select a scale based on space available and cost of the miniatures, that most of these battles involved small numbers of ships and occurred in a limited area, the large size will not seem out of place.
