The list is actually pretty short as far as
safety equipment requirements. Though it's easy to argue that everything in the list is for
safety. It's just not all about dedicated
gear. It covers how things have to be in many cases. They often represent the most dangerous things. Especially with gasoline engines. Blowing up is likely to cause death.
Of the required door prizes these come to mind:
USCG Flare kit (not expired)
Sound making device (you are too short to require a bell)
PFD's at 1 per person aboard
One throwable float for someone in the
water
2 small fire extinguishers for a
boat your size
The posted palcards are not really
safety. The nav lights I don't see as a safety equpiment more of a requirement of configuration. You wou;dn't want to run at night without them in any situation. There are others related to regualtions on
propane storage and
oil containment and some of the rest of things that are considered not for "required equipment". Personally, I think the list of required safety
equipment is pretty minimal.
In terms of what you really need I think you could start with all those but you need a lot more if you expect to be out for more than a day trip. Proper operation includes things that cross over into being safe as well. If you are thinking in terms of safety you have to look at almost anything on the
boat in terms of if it operates properly or presents any issues that might encourage injury. Of the required items I have it doubled or better as far as the number of things. I find 4 extinguishers works well for the layout so that both day and night situations have them within reach almost evrywhere.
You can also get a USCG Auxiliary safety
inspection free and they can even help you figure out what deficiencies you have as well as ways to remedy them. A USCG Aux.
member at the end of the street here does all the boats in our marina each year. It is amazing that going over them all usually kicks up a few items or issues evry year.
You can also find a list from your state as well as the USCG list.
