Can they be fantasy? if so: Mechanical wings(fly away) oil(grease the wings) and FOOD If not: Water purification system for water. Sword for killing for food. A laptop, so I could write this post
A mobile phone to get help to get off the island... A monkey butler to make my experience pleasant through fine cuisine... Mini fridge full of cold drinks...
a Flint stone for fire. a hatchet instead of a machete because ive experienced survival in the woods and a hatchet is better. a suitcase full of clothes to hang up and catch rain to drink (get serious, you guys wouldnt know how to drive a helicopter or where your going in it or a boat either)
I'd have a crew for the boat wouldn't I? It is a cruise liner after all and the money is for when I get back. But fine.
A cellphone with anywhere anytime service, a long distance two-way radio, and the guy from man versus wild who, unlike survivorman, knows what he's doing.
