Bonus points if you can type it out as incomprehensibly as possible

    sea travel is fucking magic you read boats speeds being much slower than land vehicles yet somehow boats get places crazy fast over the vastest expanses possible

    you're really gonna tell me a cargoship that can't even hit 30mph is crossing the pacific fucking ocean in 15-30 days ?(and why is it so variable? :thonk: )

    theres something fishy going on man, idk what it is, a sea-god or a sea-cult that all the sailors make offerings to and be gay for

        Sea water is salty because all of the fish fucking.

        Still think drinking sea water is cool? Think again.

      also theres these boats now that are powered entirely by the wind but can actually go like twice as fast as the wind is going, you cant tell me that isnt sorcery

            With the right sails you can sail as close as I think 20 or 30 degrees of the wind. So not quite straight in the wind, but not far off.

                Nope. the windmill on the deck is driving a turbine which is either driving a propeller directly or driving a generator that drives a propeller. The wind isn't pushing the ship, it's just spinning the wind mill, and the prop is pushing the ship.

                It's not, because you're reducing the kinetic energy of the wind, so it's fine. It's still wildly counterintuitive lmao

        It's hydrodynamics and it's fucking boss. I don't understand any of it, except in a very vague intuitive "That drawing makes sense" way.

        the wind at a 90 degree angle to the boats direction of movement can still add momentum to the boat, but does not cancel out to a relative speed of zero as a wind directly behind would. the margins are slim so theres a shitload of drag mitigating features like hydrofoils that lift almost all of the boat out of the water.

      15 x 24 x 30 = like 10,000 or something, or a little less than half way around the globe.

      they go through the night where a car would pull over at a rest stop for half the time, also the time variation is weather, having to fight wind and current will slow you down, and in really bad storms youre more focused on getting over the next wave than making headway to your destination
