Background
It's the year 2023, with current technology levels, and you have been caught smuggling a ham sandwich into the president's office an attempt to protest strict dietary laws. Furious, the national regime has sentenced you to the worst punishment imaginable. Don't worry, they're rather humane. As such, they've given you one attempt before it becomes permanent and worse elsewhere, with a strict lack of ham. Not that you couldn't possibly escape whatever that is, rather a legal escape is better on your record and far more fun.
Scenario
You are isolated on a ten-by-ten raft made of water and rust-proof super alloy of various strong metals, e.g. steel, platinum, titanium, etc., chained to the ocean floor at Point Nemo, aka you are encircled by nearly 1700 miles of ocean before land even crops up.
The raft is partially submerged, two feet deep below the waves on average and three feet above. Five-foot rails cover the whole perimeter. In the center is a one-foot-deep compartment that contains 72 hours' worth of fresh water and nutrition, for an average person, for your one-week deadline. A
A sweaty, ocean-blue jumpsuit is your only accommodation on this baking raft. At least one of the guards was nice enough to smuggle you a feather pillow with a dull screwdriver in it.
Oh, and you have an indestructible Nokia phone on a full charge, also in the compartment.
Whatever you can feasibly fit in your prison wallet is also allowed.
Obstacles
Besides the one-week escape limit, and the supplies situation, Big Brother has anchored a cruiser in each cardinal direction on the edge of a 50-mile radius. And a few nuclear-powered submarines lurking within this range.
Challenge: Escape To A Free Country
Given this set of risks and supplies, who you are going to call to come to get you from this oceanic hellhole? And how are they going to do it in tangent with you?
Be creative and think outside of the watery box!
Wrong and humourous answers, within reasonable confines, are obviously welcome.
