How can a boost regulator save energy? From my perspective the parts of it create resistance and therefore heat so energy is lost. Well not lost but it'll heat your boat instead of running your pi.
Not a big fan of the capacitor solution either but I didn't get my hands on anything > 1F yet so it's hard to judge. For me personal the safest way is the battery and I really don't want to risk to corrupt my raspbian when I'm on tour.
You are right that the energy is not lost, but he is not able to use all the energy stored on the capacitor. How much energy that can not be used depends on the minimum voltage the pi can run on, if a boost regulator is not used.
I do not necessarily mean that a super capacitor solution is bad, but it may not be much simlper or cheaper than using a battery, if you want a reliable solution.
I choose a battery mainly because I wanted to make a litium ion battery charger, which I had newer done before ;-)
You should take a look to the diypowerwalls forum : -₩)))
