Which man would you marry and why?

A horrible virus wipes out almost all of humanity making you the last woman on Earth. Since there's no one around to run anything, your world has essentially reverted back to the 18th century: there's no electricity, no running water and no convenient means of transportation, etc. With you are four men and your little gang has reasons to believe there might be other pockets of humanity spread out in secluded areas around the globe (but you can't be sure). After a month of living together, it becomes clear that you're going to have to marry one of the dudes to begin repopulating the Earth. All three are handsome, charming and compatible with you. The first is the last sailor in the world; and as luck would have it, also owns the only yacht left. The second man is a farmer who has built a spacious log cabin next to perfectly arable land. The third man is a brilliant scientist who may be able to get the world's technology back up and running. The last man is a doctor, who is remarkably adept at curing most illnesses.
