Audio alarms for radar have a tendency to sound, based on "sea -
return", so many people all too often turn them off.
If you plan to singlehand, add an AIS with CPA alarms. No guarantees,
but coupled with radar, it might help increase your safety factor.....
course, this doesn't address the surfacing sub issue.......

nothing will be foolproof

The question was asked by an inexperienced sailor. There are many
expensive devices available, but there is nothing like a real "24 hour
watch". This skipper needs crew.

Remember a few years ago when "Coyote" ran into a fishing boat off
New England? That was Mike Plant, one of the most experienced
single-hand racers on the seas. His boat was commissioned with the
latest (and expensive) gear to make it as safe as possible.

"Around the world alone" is dangerous. Even if they don't care
about their own safety, they should not be endangering others.
Maritime regulations are specific about a constant, 24 / 7 watch.
