Help no power

The fuse is by the battery switch located in the rear port storage compartment where the battery sits.

Thank you for continuing to coax me to explore further over by the battery cut off switch. There is indeed a 20A fuse there and indeed it's burnt out. Different physical size than the spares in the fuse box so I will go out and buy spares tomorrow. I'm confident the problem is solved.
I found the service manual online and it's clear from the wiring diagrams that the fuses in the fuse box are only for the engine-related components. Good to know for future reference. Also glad this happened when I didn't have guests. If there's a next time I'll have spares and know immediately where to look. Thanks all!

I'm late to the party, so glad you got it sorted out!!!

That fuse caused me a small heart attack some time ago in a similar situatuion to yours, I had no idea that battery switch site fuse box existed until talkign to @Mainah, glad you found it!!!

I realize now this fuse is in the owners manual right after the fuse box entry. I was so busy looking at that section I completely missed it.
This pic shows the cut off switch and two fuses. 3A for bilge pump and 20A for everything else on the accessory circuit (including bilge pump).
