Fall off your motorcycle and you need a ride to the hospital, maybe an ambulance. Fall off your horse or a cliff and you need some burly volunteers with good knees and strong backs to haul you to the nearest road. A little more extreme, say you are stuck up a big cliff, and you might get a 90-second ride in a small helicopter to the nearest road.
But when anything goes wrong out at sea, from a broken mast to a broken arm, you are in for the deluxe package. It starts with ships in the area diverting towards your position. Then a fixed-wing airplane the size of a small airliner launches to put eyes on you and coordinate the next bit: the granddaddy helicopter, the all-weather one with a winch, night vision, two pilots, two SAR techs, maybe three turbines and four or more blades the length of a bus. Think you are low-carbon because you are using a sail? Don't ask how many tons of fuel are spent keeping that helo in the air. (They often have to make multiple fuel stops during ocean rescues).

My point: Don't romanticize the sea to the point that rich idiots start playing around out there. Always take it seriously and do not ever expect help. Always have backup plans for your backup plans.
Buy the EPIRB BEFORE you buy the boat. Buy the expensive one.
At least when Harrison Ford got rich he started buying and crashing light aircraft. He knew to crash on a golf course so the doctors didn't need to walk very far. (Not a joke. That happened.)
