On my boat 80% of all hose clamps are not on seacocks or thru-hulls.

I cannot speak for anyone else's boat, but on my 20 year old boat most everything is as it came from the factory, and many barbs do not have room for two clamps.

This is kind of my point exactly. If you use decent clamps and maintain them properly, it is extremely improbable you will have a failure. Most failures occur because people do not maintain their boat properly. Take the example of someone who has a boat with a freshwater system that does not have barbs large enough for two clamps (which I would think is the majority of good old boats). Spending hundreds of dollars replacing all of that just for the purpose of putting two clamps on each is folly. in most cases one clamp is sufficient. Just maintain your boat properly, inspect regularly, and replace clamps that you think are suspect.

I am certainly not arguing with the coast guard regulation. I double clamp every seawater hose with a 316 clamp.
