Default Redundancy question - Lost all elec power at 27 mile

Hi, I would love to get some of you guys opinion.
I was out 27 mile offshore the other day and experienced a total power loss (except the engine power). My audio first stopped working and noticed that the vhf radio was off. Then my gps started to blink and... gone. I just had purchased a good old paper chart so was able to get back home safe.
Found out it was just a blown fuse on ACR that charges my house battery. My system has a dedicated house and engine battery. So basically the house battery was not charging at all.
For some reason I did not think check the fuse out there.....but learned a lot from this incident.

This made me think of redundancy items I should have on the boat.
My question to all is what do you guys have on your boat as redundancy/emergency?
I started to think about getting a second VHF, GPS, Satellite radio but this can be endless...
Currently I have:

1- VHF Radio
1 - Handheld radio (but it hardly reaches far)
1- GPS
1- PLB
2 battery system (house and engine)
1- Life Raft
Toolset with fuses
Bow and stern anchor

Any opinions much appreciated!

sounds like you need to learn how to troubleshoot on the water, and be familiar with your wiring. if something goes down, know why, and how to fix.

you cant plan for everything, but knowing how to trouble shoot and repair while underway is golden.

A printed diagram of your electrical system including all the fuses and for bonus points, voltages at key points. Yes, you should be able to think that through. Sometimes in the heat of the moment, you don't think too well.

Checklists are a wonderful thing when bad starts happening.

If your crank battery is charged, but your house is dead you need a parallel switch to allow you to combine both batteries. If you combine both batteries your electronics will work and your bad acr will be bipassed allowing the house battery to charge. Just keep your engine running until the house is fully charged. Problem solved.

As a backup to your boat Electronics, you could carry handheld electronics...
- VHF handheld
- iPhone in waterproof case (Lifeproof for example) w/ Garmin App and Navionics App.
The GPS works even when out of cell range.

While you are at it, rig-up an adapter for your handheld VHF to run to your main antenna. An additional 8+ feet of height will help your range.

Thanks for many great ideas!

Sometimes in the heat of the moment, you don't think too well.
That is so true. I knew what had happened but with a brand new boat, I got caught off guard.... I am usually very good at electrical. I do everything on my boat myself so I am pretty confident on things but heck, I did learn my lesson. I guess we keep learning every day
