Maddie knows that their team was designates to land just south of the Texas shoreline so she knows that their best bet is to go north west. Using this knowledge they will head in that direction and reach land. In the event that they don't they will still reach land one way or the other because local winds that come from the main land create winds that make wind waves that allow for anything that floats to wash up in the coastline, and even further ocean currents naturally go along most great land masses that even if their raft gets carried away by one they'll be close enough to paddle to shore.

As for where in the map exactly they'll land you can pick a place in map I made for the Texas. For this first story arc our goal is to get them to non swampy area, in other words, mainland. Realistically speaking walking from the coast of Texas, let's say, Corpus Christi to San Antonio (both line up in the map of Texas i have up there) would take two and a half days without stop. i did the math and If we factor in the fact that there's no road, they have to make stops, unfamiliar territory, and external variables it will take them possibly a week before they can leave the swamp area, which should be a good enough time for one arc. 

By the way there are oars on each side of the raft, but i forgot about it in my last post. As for the look of their raft it looks kind of like[url=http://z.mhcdn.net/store/manga/412/03-010.0/compressed/Seven_Seeds_vol03_ch10_p078.jpg?v=11192170003]this[/url], but around this [url=http://i2.ytimg.com/vi/mdcMemn8Ses/mqdefault.jpg]thing's[/url] size albeit shorter. All of it is made of made of a colored plastic rubber like synthetic material that's both durable, solid, but light and allows them to float on the sea's effortlessly. Surrounding the entire thing and underneath the raft are rope floats that keep the raft steady and floating, and the same goes for the rope that keeps the two rafts together.

Honestly, I think i should have worked on a better way for them to get started in the world. I don't mean the intro, but with the whole aircraft shuttle thing, but it was either that or have them asleep underwater in some kind of rising machine, which would have limited all teams to start by the coast and make their way inland, but that would have limited exploration and environment types. What do you think? Is the whole aircraft shuttle thing and being in space kind of dorky? I mean we're not gonna change it, but coming from a reader's perspective what do you think? 

Sorry about the above I've just been organizing my writing and that thinking came up.

EDIT: So I jut finished reading you post. Lovely and already in character, I'm jealous, it usually takes a good few pots before I get the hang of my guys. Also the fact that they're wearing Georigia shots kind of make me happy. 

Also they all have their own rooms with one bed for privacy. If that's not what it read like from when I wrote it I apologize. Basically the dome has an external shell which is thin and acts as a cover,and inside is a smaller dome that's cut four ways like a pizza. Each room has one skewing pod and there stuff. If I wasn't clear anout it when then I'm vey sorry. It's all my fault. Don't worry though you don't need to change anything it's just for the future since theyll be spending some time in this rather large raft. All this really means is that I still need to work on my writing.
