Condolences to the sailors family. Loss of life is a terrible thing.

But it happens less in sailing than many sports and just life in general. After all it's living that kills you.( If you don't live you can't die).

As far as trap hooks go, I rescued a cat sailor that was caught under the tramp on a wire strop that connected the Boom Vang. But it wasn't caught on the hook it was caught behind the plate that held the hook. Just can't fix every possible cause of entrapment.

Have fun and don't do anything that "you" are not comfortable with, that's as safe as you can get.
