How do u get a boat or unit to carry someone?

i havent figured out what the ablity is or what exactly u have to doto carry someone

It is something like 'load units'

well there is diffrent kinds but not units or heros

it should be something like BadFurDay said, it should be load units, and for carrying ull need a cargo hold ability(ex : the transport ships thing is cargo hold(ship), load(ships), unload(sea transports)) hopes that helps
