How do you make a npc spawn in a item in a certain coordinate?

Im trying to spawn in a boat with a NPC but I can't seem to spawn in the boat with the NPC. What script do I need to do that??. I have the NPC done.

Like In one piece golden age theres a NPC that spawns in a boat in a certain spot (ex to left or to right of Npc).If you dont have a boat the NPC says you dont have a boat so then the npc show a dialog thats says buy boat and you click it and a GUI pops up that has a boat you can buy with gold.I don't know how to make that happen. Any websites or something that could help?

Have you tried grouping the NPC with the Boat model? They will probably spawn together if you do that. Depending on how a player spawns the boat.
