providing the shell is clean of contaminates, I agree with you. The powers to be believe they wont last long enough(at least that what i think is the go) and that sinking them is akin to 'sea dumping'Night Stalker wrote: no shortage of car wrecks
anyway - like you say there are heaps of them and they are modular - ie they can be sunk one at a time using smaller craft to do so. like a small barge. it would only take a few trips and you'd have the current reefs built up.
I'll continue this post in the reef makers thread.
