suppose i put a message in a bottle and throw it in the ocean. assume i’m on land, not a boat, but you can pick any land mass in the world. is there any realistic chance of that bottle actually crossing to another continent? Or will the waves almost certainly toss it right back on to the same beach it came from?
How about UK to Australia?
Not quite ‘a bottle from shore’, but rubber ducks from a container ship:

A friend of mine tossed a plastic bottle with a message into Lake Michigan.
Many years later, it was retrieved by someone in Venice, California. One theory is it made it over Niagara Falls then thru the Panama Canal or around South America.
What are you losing by trrying that except for time? If your random, lonely message was to reach another person anywhere in the world, wouldn’t it be better if the sympathetic recipient was also a neighbour?
I know this guy!
I actually tried this, I threw a bunch of bottles in the Atlantic with notes, asking the person who found it to write back to me. I was living in West Palm Beach. Two people wrote me back. One was in Jacksonville, FL and the other was in Hollywood, FL. If I recall, I threw about ten bottles in the Atlantic and two were actually found. Or the others were found and no one wrote me back.
But anyway, they came back to the same side of the Atlantic. Jacksonville is like 250 miles from West Palm and from West Palm to Hollywood is about like 50 miles if I recall
It will go at least as far as your local movie theater: Message in a Bottle (film) - Wikipedia
I think the odds are small if you heave it from the shore.
Most of those message-in-a-bottle stories seem to involve dropping the sucker offshore from a boat where currents can take it somewhere.
Near the shoreline the waves tend to bring most floating things back in and deposit them at high tide. Maybe a lucky toss into a big river, but off the regular shore…I’m skeptical of your chances (although they are not zero). If you can pick any land, maybe teeny atoll somewhere? The trick is to get it out past the breakers.
