When I was in my late teens, I ended up on a boat from Ft Lauderdale to the Bahamas. Theres no way no to go through just a little bit of the Burmuda Triangle. I remember freaking out / being super excited, wondering what crazy stuff things would happen on our journey. Of course, nothing happened. I was so disillusioned.
The triangle is HUGE, and due to where it covers, a lot of shipping went through it, and still does iirc.. Saying its dangerous because ships wrecked there often isn't that far off from calling Earth dangerous since every human has died there. It's a true statement, I suppose, but the context helps understand it's not a very reasonable one.
Yeah the mystery of the triangle was puffed up by disingenuous authors who lied and fudged details to pretend ships went missing all the time. Things like reporting ships missing but not their eventual returns, claiming there were no storms when records showed otherwise, including sinkings and crashes that happened well outside the triangle, and a bunch more.
When the the data is analysed; the number of incidents is the same as anywhere else on the planet.
My understanding is there's a lot of coral reefs in the Bermuda triangle and, like you say a lot of shipping with through there. So it makes sense a lot of ships went missing in that area.
Sailors are a superstitious lot so there were stories about it being cursed. Kinda like how it's bad luck to carry bananas on a sailboat.
