Maddox kicks so much ass. That is exactly the kind of science and logic that these conspiracy nuts use. I've seen it before, but I LMAO every time I see it.
Anyway back on topic. Aluminum is subject to pitting corrosion in the presence of the chloride ion, so it will corrode in sea water.

Damn, that would be an awful big ship if it is big enough to carry a sea!mopherman wrote:well, my science homework had an interestion question today so i thought i would share it with you.

I suppose you meant a "sea-going" ship?
The "cheaply" part is the most important part of the question. In this case "cheaply" translates to "how it is actually done in practice" since "in practice" is basically the same as "cheaply".
Like everyone else said, ya paint it and attach sacrificial electrodes. It is the only cheap solution.

My favorite Maddox. I've read The Alphabet of Manliness! Has anyone else? It rules!
On topic... A zinc coating, like others suggested, would be a smart move. I don't know how expensive Zinc is, but you only need to apply to about 15/1000" thick coating, and run an electric current through it.

and over time they would need to be replaced, while a wood ship would never rust, seeing that it isn't made of metal.

Nope, wood sucks as a building material.

Wood rots in water. Untreated wood looses almost all of what little strength it has after submersion in water for just a few weeks.
Worms, and other organisms, eat wood.
How do you hold the wood in place? Wooden pegs? Any type of metal fastener will be very difficult to protect since most of the fastener is inaccessible.
So, the wood won't rust but it'll fail for a dozen other reasons long before a metal hull would.
With proper paint and a sacrificial electrode a steel hull ship will last essentially forever.
The next best materials to use for the hull of a large ship, after metals, is probably concrete, then fiberglass or other plastics.

Sandman, ya, if it is OK if the ship melts within a year or two
The only pratical way I can think of to freeze a boat size volume of water + saw dust would be to do it in a place where the ambient temperature is well below freezing. You would also need a source of pure water, salt water would be almost impossible to freeze.
The same factors that make Pykrete slow to melt also make it slow to freeze. So, WAG suggests that to make a boat that won't melt for a year will take at least a year to freeze in the first place.
Course they leave out one minor detail. It takes a lot of energy to freeze water. To freeze lots of water takes a huge amount of energy.Pykrete can be easily formed using water and any porous and fibrous material, such as shredded paper or sawdust. Anything that can be molded with this wet pulp will freeze and become strong and non-brittle.
