I have a caravel and a scout and I am trying to get the scout on the caravel so he can explore a land mass across the ocean. I can't seem to figure out how to get him in the ship. Is this not possible in Civ 5 since the scout can ride in his own boat? Do I have to wait for a better ship than a caravel like a frigate?
Your scout can just move into the water and sail all by himself. It's called embarkation.
The ability to embark a unit into shallow water is unlocked by the optics technology. The Astronomy technology expands this ability by allowing units to also move across ocean tiles, not just shallow water.
- Embarkation is a promotion. A unit has to have passed through your territory at least once since you have researched the technology in order to gain that promotion.
- All Polynesian units receive the embarkation promotions for free.
- Movement speed of land units in water is 2. You get another movement point once you research Astronomy, and another after Steam Power. Adopting the Naval Tradition policy also increases moves by 1. Danish units also receive 1 extra move and England gets 2.
- Embarking (moving from a land tile to a water tile) and disembarking (the other way around) waste the entire turn, i.e. you only move 1 tile. Danish units are exempt from this penalty when disembarking.
- Your land units are helpless in water unless they have the embarked defense promotion, so consider escorting them. All Songhai land units get this promotion for free.
- Embarked units are not considered as water units (for example, the great lighthouse doesn't make them move further).
- Embarked units cannot pass through friendly cities like ships can - they must embark and disembark to cross them.
You can't put units onto a ship in Civilization 5.
Instead, ALL land units can simply move into the water in order to "embark" and build their own transports.
However, while embarking, land units are completely defenseless and classified as civilian units, so you will want to escort them with the caravel.
Short answer: just move the scout into the water, then keep it near the caravel to keep it protected from any barbarians or enemy civs.
