This is probably not the right place, but I figured I'd give it a try. I've been trying to copy this website so I could have offline access when tooling around the Channel Islands. I could (and probably will), just copy/paste whatever info I need for my little trips, but the fact that I can't copy it ass over is annoying the hell out of me. I've tried variations of wget -r ... as well as httrack with no success. Anyone have any idea how I can get this?
Another option is to use the SingleFile browser extension. You can install it from your browser's extension marketplace.
SingleFile can download an entire web page into a single html file while preserving the layout and images. It basically inline everything into a single file, which is very handy. The drawback is you'll have to do it manually on every page you want to save, but it works really well. Even the google map embed in the page you linked got preseved as well (it's not interactive anymore though because it's not preserving javascript).
I'm trying to get all. I mean, I've pretty much manually copied most of the info already, it's just that I can't do it all at once that is bugging me. I'll go out to one of the islands, and there are numerous anchorages. So what I've been doing is copying the one or two that I know I'll be going to, then picking a couple alternatives so I have options. It's not the end of the world, because I'm not a complete idiot as I do have NOAA charts and can navigate with them, it's just that website is great for specifics on the spots.
I’ve used ArchiveBox as a desktop app (on Linux Mint) which saves a snapshot of URL’s you feed it. Worked for the sites I needed when seeking an offline solution.
