See topic. I want to use them with a Garmin handheld device. I can do transformations from, e.g., OpenStreetMap myself (with some instruction).
Finally a real fuckin pirate
this is one of those things i wouldn’t pirate. maps and weather are extremely important when sailing and having legitimate sources of these things is something you should be doing. you wouldn’t pirate a first aid kit would you?
you should be doing the anti piracy commercials.
Does paying for something make it better?
Or is that a capitalist illusion?
A movie? No
A piece of information that your life might depend on and you need to trust the origin of this information? Yes
I would buy charts if you need them for life and death reasons but if you are open to using older charts for interest and leisure purposes you could use the CM93 chart set. This is a world wide set taken from possible copyrighted sources and crowdsourced info. Of course we cannot direct link to potentially copyright infringing files from here but this thread on cruiser forum discussing the charts may point you in the right direction.
Not sure if they work on garmin natively but they are fine with opencpn.
Remember they are about 10 years old and come with no guarantees.
Failing that openseamaps is pretty good, though lacks bathymetry data.
