Several posters keep insisting the Route Guide was some kind of woefully inadequate IMC letdown procedure or instrument approach plate. I believe you're giving it a status it doesn't deserve, and then criticising the designer, management, etc based on your own misinterpretation of its purpose. The IMC letdown had already been achieved prior to commencing the route shown on the diagram. No doubt the company has night/IMC overwater letdown procedures which presumably is what the crew followed prior to routing towards Blackrock. According to the report,

"The Commander's stated intent was to complete the APP1 procedure prior to turning east towards waypoint BLKMO to commence the arrival route to Blacksod Lighthouse."
The APP1 procedure was the descent to 200'.
