Safety equipment is something we spend an exorbitant amount of money on and never seem to use. Ours includes: Zodiac 4 man offshore liferaft; MOM 8A overboard recovery system; Inflatable Lifesling; Inflatable PFD’s with built-in harnesses and dual tethers; standard offshore PFD’s; 406 GPS EPIRB; ORC Class 1 Flare kit with 6 SOLAS parachute flares; handheld submersible VHF radio; a Bose Stereo, but No television.
We use the stereo regularly but have never used any of the safety equipment except in practice sessions. Below you can see the Lifesling, a throw rope pack, and a Mustang inflatable PFD with harness. Our liferaft is tethered to the boat ready to launch. We replaced our 120 pound racing liferaft with a smaller, 45 lb. unit. Hate to say it, but I’m getting older.
We always wear our inflatable PFD’s / harnesses tethered to the boat when offshore, at night, or whenever conditions dictate. Each PFD has strobe lights, whistles, crotch straps, and personal flares attached. 
We hope to never use this gear.
