I recognize that I have a problem with parameters on this question, so go ahead and throw in any suggestions abotu what should be included and excluded.
Obviously small boats like canoes and rowboats are out, but I still am not sure what the minimum size should be.
Part of me is wondering how many of these shipwrecks are recognizable right now, and part of me just wonders how many boats have sunk in the last…6000 years or so.
I also don’t know what they did with old boats back in the day. Did they just sail them around until they sank? Did they take them to sea and scuttle them? Did they get dismantled?
I guess you can see the problem with defining this question.
