Running a ferry for so long is ridiculous. Only in this Washington / BC bubble is it normal. BC Ferries is second only to WSF in fleet age for major ferry providers in the developed world.
The Coho is sort of neat because it's old, but it really should be razor blades. If she were subject to Canadian regulations she'd be long gone or very extensively renovated (see: Queens of Nanaimo, Burnaby, New WesT)
Finally, the retirement of the BC Ferries is literally keeping the Coho alive. Some pretty major components are from the Sidney for sure, and I've heard passive rumour of the Tsawwassen (which is still in use but not under its own power for movement at least)
