For example, Allen talks about drogues he was using, he also talks about sea chutes, etc. Then there have also been discussions about tandem anchors, etc. on this site. What's the skinny?
Drogues and sea anchors (or the quick easy way - just drag something behind you that sinks) are used in heavy weather to slow down a boat in fast or high level waves - mainly on the downhill sled of the wave. Principle is like this - take a dock cart heavily loaded and go up the ramp at high tide (there will be an angle on the ramp if you have those floating piers - if you are manly enough and do not have floating docks then use stairs)..If you push the dock cart up- all the work you have to do is countered by the resistance of the dockcart naturally wanting to slide down. This in effect is what the boat does climbing waves - loses momentum...When you get to the top - its easy to get the cart moving faster (ie downhill) and if there is a downhill slope you now have an almost runaway cart...(gains momentum)

Dragging the sea drogue if it is the right distance away from the boat will prevent the downhill momentum allowing a more comfortable slide down the wave because it will be providing the resistance needed to slow the boat down and maintain a slower momentum (like brakes on a trailer)...

Practice with just the main or the jib out - but keep the motor running and ready to engage. Probably the safest way to do it - things get out of hand you luff the sail and use the motor to get back to a position...Easiest way to practice and have that piece of mind...

You stated "non technical" and that's how I would explain it for the most part...
