copper-bottomed

The very kind of case a real copper-bottomed expert would be some use in!

But Toplinskys stomach was cast iron and copper bottomed, and just a slight hesitation flickered across his face.

His copper-bottomed ships came up with and captured six of the enemy, five of which were English prizes.

The wreck proved to be a beautiful copper-bottomed schooner, of about a hundred and eighty tons burthen.

Otherwise we caught nothing, as heretofore, because fish most generally avoid copper-bottomed vessels, such as ours.
