Any one ever seen this used for structure? In my local lake the co. dive them has sank old boats (take motor off and gas tank out) to use for practice on air bag lifts, rescues, and whatever else they do with them.
They say that there is always fish in and around them. Makes good since to me. They will last for ever. Can be taken out if need be. keeps them out of land fields, and out of somebody yard.
They do old ships all the time.
