@danryckertSince it's a recurring question in this episode, here's my attempt at a simple summary of why shipping by boat is generally preferred:1) Boats float. Keeping them afloat doesn't cost any fuel, and moving through water is easy because there isn't much friction. Think of pushing a rubber duck on water versus pushing one on land - which will travel further? Boats are slow to get going, but the cheapest mode of transport once they're in motion (even cheaper than road travel). Planes are fast, but you would need dozens if not hundreds of trips to transport what a large boat can in a single trip, and an awful lot of fuel is spent just on getting planes off the ground and keeping them in the sky, which is expensive.2) There isn't actually that much benefit to companies in having things arrive there faster. Manufacturers plan ahead - they don't suddenly decide "we should make this now" - so they can book supplies to arrive when they need them. For most goods it really doesn't matter how long it spent in transit, as long as you have a steady supply. When a consumer orders a PS5, they want fast courier delivery because it's just one PS5 and it's no good to them until it's in their hands, but a company will be getting regular deliveries of the supplies they need.Say for example a manufacturer uses a ton of iron every day. As long as they have sufficient storage capacity, it really doesn't matter if they get a delivery of 7 tons every week, or 30 tons every month, or 365 tons every year. Likewise, if they're getting one delivery a week, it doesn't matter if it was dispatched from the supplier on an express flight the previous evening, or on a boat a month ago. They might even have several boats on the way to them simultaneously - a new one could be dispatched while the previous one is still in transit.
