to take a inexperienced young family (passengers really) into this type of undertaking with no additional crew for backup seems a very big risk to me
Doing the inside passage is a big trip, but I think it's within the capabilities of most C-Dory owners with a modicum of experience. It's certainly a popular route, and lots of people do it every year in all kinds of boats. I've actually made the trip before, albeit many years ago and in a bigger boat.
The main safety issues (other than those inherent in being in any boat anywhere) revolve around the remoteness of many parts of the route. As someone who grew up in Alaska, and who has lived in Africa for the past 14 years, I've come to grips with traveling in remote, and even dangerous areas (heck - I've been to Timbuktu. It's not far from here).
The issue of taking young kids along (mine are 4 and 5) is indeed something to think about. My wife was certainly concerned, although more from the "cooped up in a boat for 10 days" standpoint than anything else. Safety wise, bringing them didn't exceed my comfort level, but then I've driven them from Niamey to Ouagadougou traversing country which is undoubtedly more remote, and probably a good bit more dangerous than anywhere on the inside passage.
It's possible that my comfort level has been shaped beyond that of lot's of people, but I do know its limits. A few months ago there was a lot of discussion on the site about the possibility of taking a C-Dory across the Gulf of Alaska. Now that’s something that exceeds my comfort level. I played it safe and shipped the boat across in the hold of a ferry, and I wouldn’t have considered taking my family across the Gulf for anything.
Yes, it's important to prepare. It's even more important to adapt, which is, if anything, the message I'd want people to take home from my account.
I once read a quote from an early Africa explorer who said, "While an adventure is transpiring, it's merely physical and/or emotional discomfort. It needs time to age and mellow, and only actually becomes an adventure when recalled later in comfort and repose". If you want to have an "adventure", you have to be ready to experience a lot of things, not all of them good. I certainly don't believe in looking for trouble; my kids wear bicycle helmets and fasten their seat belts, but I don’t want to raise them in a cocoon, either. You've got to get out there and live life.
