Breed the best, cull the rest? Row with the oars and use the axe on the swimmers if they try to climb in the lifeboat? White Nationalist Ecofascism? Is that what you find "deeply disturbing"? Why don't you face the music now so that you'll be ready to grab a chair when it stops?
I rather figure out how to make the lifeboat larger.
Or maybe we can improvise many little rafts.

To build a real lifeboat is a considerable task, even if you have all the tools, materials and knowhow. Rafts are quick and easy--not as good as a lifeboat, but note that had the Titanic been equipped with the cheap kind of rafts that U.S. warships carried in World War II (Balsa wood with canvas or tape around it--had one as a kid--very cheap, unsinkable and would not capsize unless waves were driven by winds in excess of about 80 knots. Had lattice bottom so your feet were always wet, but the sharks could not get you.) By analogy, we need something quick, easy, cheap, possible to create quickly in large numbers, something effective, not necessarily something efficient or elegant.

Any ideas?

And please, no monasteries. They are no fun.

Architecture for extremely modularized and easy to mass manufacture high rise buildings that do not look awfull and can be built quickly to form urban centers in existing mall areas.

A social movement for car sharing and other local cooperation. In USA you can benefit from your religious traditions in starting such movements.

Move your capital to companies that provide post peak oil usefull products. Preferably local companies whose workers you can have a personal relation with.

Dont stockpile gold and guns, stockpile roofing material, cloth, usefull stuff that is too bulky to steal withouth a truck.

Invest in making friends.

Sweden, its a raft compared to the world population. My focus is trying to make it a little better and to be generally usefull.

Magnus, you are a genius! You have seen that the #1 best investment is friends (also children and grandchildren, for when you get old and feeble, like me;-)

With a network of friends and neighbors, with a community we can live and thrive. Without these, forget hoarding food or guns or anything at all. Hint: For security and self defense, make friends with veterans and active-duty soldiers, sailors, and Marines.

Many little rafts is probably a better idea than one big one.  That way, a mistake by one won't drag them all down.
The metaphor breaks down but there is nothing hindering nested peak oil rafts.

From fairly well managed countries and states to regions with significant hydro power and nuclear power to towns with good peak oil infrastructure to cooperating small size companies to cooperating neighbours to fairly self sufficient families.

Preferably organized in different ways to give better redundancy and competition that inspiers others via the net and the market. Then it will not hurt as much if some of them fails and others can learn from their failures.

There is no optimal solution. Therie is no golden road. The best I can think of is to on manny levels have social processes for finding better solutions all kinds of problems.

I'll put in a plug for my favorite liferaft builder: Post Carbon Institute.  From my point of view, rebuilding from the bottom up makes a lot of sense, given that the top level (Federal Goverment) is ineffective and out of control.  Rebuilding at the grassroots also empowers individuals to actually do something about the problems.
My contribution to a raft idea would be electric trolley buses.  Not as good as electric rail for urban transportation, but quick, cheap and easy to install.

Try to run one within 800 m, a half mile of everyone in an urban area.

Minimalistic, but useful.

Not only useful but a thoroughly demonstrated technology. Also, it occurs to me that the extra labor required to build the overhead rails might help to mitigate the huge unemployment problem that PO will sooner or later trigger. We can never do only one thing.

Also, the electric trolly buses I've ridden on in San Francisco seem nice and quiet and of course free of fumes . . . and reliable.

Would you like to run for president on the Electric Party ticket?

"Let's electrify transportation."

"Electrify now!"

"If elected, we shall electrify you within four years."

In Vancouver, BC they've been running Electrolic trolley buses for 50 years.  They run throughout the city.

While they are getting old, and are due for an upgrade before the Olympics in 2010, they definitely serve their purpose well, and who knows how much smog and money (due to very low electricity rates in BC) they've saved the tax payer over that period.

My greatgrandfather was a Victoria BC streetcar conductor!
