As for regular yachts - drop a drogue, run before the storm with a bare minimum of sails up to maintain steering ability, try to keep the waves on your stern.

Also surprised at the scale of the things, the smallest model is 7 m (23 ft) long, the largest is a whopping 22 m (72 feet).
Pretty cool things!
They footage IS very cool, for that matter what do EXPERIENCED boaters do if their sailboat or motorized boat get caught in a bad storm?
Nowadays I'd say experienced boaters never get to that point. There's reliable weather forecasting and near-instantaneous radar data. You can avoid the storms.
If you’re stuck at sea with a hurricane barreling down you can try to sail around the equatorial edge of it (in the northern hemisphere you try to sail south of it). Hurricanes tend to veer away from the equator. Moreover the wind and waves will be behind you, so you’re less likely to get knocked over by a gust or a wave. The boat is quite literally surfing.
If things get really bad you might heave-to which is a way to work the wind against itself causing the boat to mostly stall. It’s supposed to be very safe in heavy winds, but you would be pointing at the waves which is bound to be unpleasant.
Finally, a sailboat’s keel is very heavy. Check out the diagrams at [1]. The mast has to be well below water before the sailboat prefers turtling to upright.
I am far from an expert on this topic, but for sailboats; sea anchors and storm sails. The first is a parachute-like device that keeps the boat pointed in the right direction relative to the waves. The second is a small, tough sail used when any other sail, even while reefed, would be too big.
If you can't make it to shelter in time, it's better to weather the storm in open water than near the shore - at least that way, you won't risk hitting something and sinking.
The very best way to deal with heavy weather is to be on the shore.
Also, at least in the US, typical boat insurance is very expensive if you want to have your boat anywhere near hurricane "areas" during hurricane season. People up here in the northern US like to take their boats down to Florida or the Caribbean during winter, but generally their insurance policy is null and void if they get there before Dec 1.
