I also have labels around on things, and probably could use a few more.
Things like "Do not use key to shutoff engine, push and hold the black rubber button. AFTER engine is off, turn off key."
I have one of those cheap office labeling printers (p-touch?). Works okay for this kind of thing and you can buy UV resistant label tape. I use that for clutch labels and stuff too.
Great idea. If the manual could be made redundant by the labeling, then the manual becomes a checklist for the orienting captain.
Imagine an emergency, say the captain is the MOB, struck by the boom. Maybe conscious, maybe not. The Jibe was obviously sudden and unexpected to catch the captain off-guard. Winds are squirrelly with a following sea. If the passenger who witnessed the event remembers the basics of the captain's instructions, the passenger yells at the top of their voice, "MAN OVERBOARD!!!", and they work to keep a steady eye on the captain's position. They reach for a floatation device, preferably the life ring or horseshoe float.
If that's all they remember of the MOB briefing, or have the where-withall to figure that part out themselves, they are doing incredibly well for an uninitiated sailor. Still, no rescue is forthcoming, as of yet.
Now, if they are not alone onboard, our captain has a chance. The other passenger(s) have to figure out how to stop and/or turn the boat around, or activate the Digital Selective Calling (DSC), or throw the Emergency Position-Indicating Radio Beacon (EPIRB) overboard with the life ring, if the first passenger didn't have the presence of mind to throw the floatation device right away.
There may be one or so passengers thinking, "What does the manual say to do, but probably doing, even ineffective doing is more likely to happen.
Do they know how to heave-to? They can at least figure out how to release the sheets (not overly effective when running down wind, but still...). Maybe even bring the boat around into the wind. It is a lucky break there isn't a spinnaker set for this downwind run.
Now, if there was a nice clear short label that pointed to the DSC button with and "IN CASE OF AN EMERGENCY INVOLVING THE CAPTAIN, DEPRESS BUTTON FOR FIVE SECONDS." Looking quickly around, maybe they remember seeing the Life-Sling label on a cockpit locker, along with the flares, and one of them notices the small, but prominently displayed sign near the helm that instructs the helmsman to bring the boat into the wind to drop the sails, rolling the headsail in before the main to reduce the danger of injury or damage from clew flailing.
Labels on the engine controls would instruct the operators to turn the key into the on position before starting. The neutral, forward, and reverse positions of the throttle would be indicated. A label on the radio would point out that channel 16 is the Emergency channel and give the protocol for a mayday call, including a reminder of the vessel's name. A label might help to find the GPS lat. and long.
A laminated card that described the figure-eight maneuver, with or without sails up, could hang by a short lanyard from the binnacle. A reminder to approach from down wind, when possible would be a nice touch, and a label on the boarding ladder that told the rescuers how to deploy it would also be desirable.
I think the book is good. There will be those who are simply interested in reading some of it when they are sitting around, but I can't see it being useful during the emergency. Keep in mind, emergencies like an MOB tend to happen when the environment is turning against you. There's likely to be other issues to deal with at the same time.
If the one passenger who saw the captain go overboard was alone and had no one else to call for help, keeping an eye on the MOB would be near impossible anyhow. Having to turn the page on a manual just isn't going to happen.
