If you are looking for an equipped dinghy in the USA. Here is a link of the US Coast Guard requirements. If visiting from another country these requirements may apply to you too! Good Luck and Stay Safe :-) https://www.uscgboating.org/images/420.PDF

The USCG publication looks like a fantastic reference. I think anyone who reads this would be well educated in safety and best practice. It is clearly inspired by wide experience of incidents. All sorts of interesting little nuggets too - I liked the craft/crew capacity guidance table.
Also, Paul, I don't understand what point you are making about the anchor chain guidance? But thanks for prompting me to look at it!
