It's a bit of a reach, but the safest way would be to attach to the bow eye. Safe for the boat at least. May be a good way for you to go for a swim though trying to reach it!
One option could be to make up a short length of line with a quick-release shackle on one end and a loop on the other that you can tie your anchor line off to. Then you can simply reach over the bow and snap the short line on, then tie the anchor line off from a comfortable sitting position.
You COULD attach to the bow lifting ring, but you risk chafe on the bow gel, and the line will tend to pull the bow down more if there is a lot of strain on it from wind/waves. And a 16 doesn't have a ton of freeboard to start with.
One thing I DON'T recommend is attaching an anchor from the stern. If the wind/waves come up you'll risk swamping
