I recall one dark, but not stormy, night when I was about 10 having to navigate from Dangling Rope back up to Halls Bay (getting close to 30-years ago, prior to GPS and lighted buoys). We had run down to Rainbow Bridge in two boats, my dad's 16-ft Baja and an 18-ft Baretta. No issues getting there, but when we went to leave the Baretta wouldn't start. We towed it down to Dangling Rope and then determined the starter was bad, but didn't have one there. They had one run up from Wahweap while we killed a few hours eating ice cream and such. After they replaced the starter they asked, "How long has that alternator been squalling like that?"
Sure enough, a bolt had fallen off the armature and was loose in the alternator. They didn't have parts for it, but they let my dad and my uncle use their tools and shop to disassemble it and patch it back together enough to get the boat running again. By this point it was late in the day and it was clearly going to be dark before we made it back up to the houseboat, but not seeing many other options we set out. On the bright side, my aunt noted that it would be a full moon that night, so we should have good ambient light to be able to hopefully pick out the channel marker buoys.
We made hay while the sun shined, but only got back to around Rainbow before darkness set in and we had to slow down. From there on, we had my cousin-in-law (who was red-green color blind) in the bow of the Baretta searching for (red and green) buoys with a Million Candle Power Spotlight; when he spotted one, we'd kick it up and race to a little past that buoy before dropping off of plane and searching for the next buoy. So went our arduous crawl back up the main channel, all the while we kept wondering when the clouds would get out from in front of the moon. We eventually got back to the houseboat at about 2AM; my aunt consulted her farmer's almanac that she carried in her purse and discovered that it wasn't clouds, but had been a full eclipse of the moon that night.
I've never done it in a houseboat and would only do it in extremis. Even with a chartplotter and loads of experience navigating restricted waters at night (Inside Passage to Alaska), I don't trust GPS as my sole means of navigation; if I had a good radar to compliment my chartplotter, that would be another story...no, I still wouldn't do it unless I had to.
