I'd try to do both, enjoying my life on the island while preparing for an eventual departure. But it also depends on the size of the island and the
amount of resources on it. I'm going to assume there are plentiful resources & a lot of bamboo, the perfect building material.
I'd probably built a hidden shelter deep in the island in case someone else landed on it. That's where I'd sleep every night. But I'd also spend a lot
of time designing different types of rafts & eventually boats. I'd also make crude weapons, tools and accessories for my eventual trip.
Assuming no one else came to the island, I'd start testing the different rafts & ships by the 3rd year. By the 4th year, I'd expect there to be
constant flooding on the island. I'd use the constant floods for training; meaning, I'd test my fishing skills from the rafts/boats, test how much
weight the rafts/boats can safely carry for extended periods of time, etc.
Once most of the island was constantly submerged, I'd finally decide to move out. I would probably wait until the last minute though, since I doubt
the island would just suddenly sink 200 ft under the water. I'd probably go out on my largest boat, and have smaller rafts on board.
I'd hope that I could survive off of fishing & collecting edible seaweed until I reached my next destination. But I'd also be prepared to deal with
pirates or others at sea, win or lose. Though there's no guarantee they'd fight or hurt me; there's always the possibility of deals.
A small alternative is to stay around the sunken island. Even if the entire island was submerged within 5 years, that doesn't mean it's useless. There
are plenty of lagoons in the world, and they can still have plenty of resources, food, and more. You just have to go underwater to get them. So in
that case, I'd probably use the 5 years building floating rafts, huts, and much more. And I'd make plenty of twine & rope to keep everything tethered
together.
This option may sound stupid but I've seen several poor villages around the world that had to build their bamboo homes on stilts because of the
sinking land and constant flooding. And there are other villages where people live in virtual boathouses because most of the land is now constantly
flooding. So I might spend the 5 years building a series of floating platforms & boats. Depending on how massive some of the platforms are, I could
even have large clay flowerpots to keep growing different crops. And there's the obvious fishing & diving to the parts of the island with certain
other resources.
