So, what happen to large yachts that sink in riverways and are either way too expensive to remove or will disintegrate and contaminated the waterway? Is it illegal to do urban exploration on abandoned ships/yachts or sunken ships?
I guess larger government ships or active bomb sites might be very illegal, but what about small private yachts?
What about those small private yachts that you sometimes see in waterways, that are sunken but just barely floating OR the water is too shallow for it to sink completely? Can you board those and look around? What about taking items from them?
How is ownership managed by these abandoned boats? If you wrecked a yacht somewhere and decided to live there, could you legally keep people away from it? If you woke up one night to some urban explorers walking around your quarters, could you shoot them for trespassing?
What about this one: You see a abandoned boat sunken on a lake, and decide to shoot it for no reason. You fire a few shots and get bored and go home. Later on, you see the area barricaded by police cars and crime scene tape. You later learn on the news that some guy had been shot dead in his sunken boat that he legally owned and had been reported by his friending coming around to visit him that day. You decide to turn yourself in, what happens?
Also, is it illegal to sail your boat in a dangerous state? For example, you buy a large yacht, but your mechanic discovers that it is riddled with holes. You ignore him and decide to take it out anyway. Let’s say you sail it on a waterway that is used as dumping grounds for power/chemical/manufacturing plants and landfills, so it is generally toxic and filled with filth anyway, so that a abandoned boat would not damage it by a noticeable amount.
Also: is there any way to legally ‘build’ new ship wreckage sites? For example, can you legally buy a boat and sink it somewhere to create some new wreckage? Is there anywhere on the earth where you could do this?
