does the boat need to consist of only ice?

^Good question
Well, if I didn't need the mummy, do I need the wood pulp?

^ yes.. yehp very god bung

I compact the wood pulp, and put it around the ice ship (which was created by pouring Lake Water into the mold, and then refrigerating it) to reinforce it.
Then I sail it away?

u throw the mumy wood and ice into a blender to make the mixture, taste it and realize all u really wanted was a good smoothie and drink the whole thing

^ right o.for bungalow.. "just stfu cassanova i said no mummy" . the mixture i called pykrete it can with stand a torpedo let alone melting... a 60 ton ship was actually built and it never meltd in a very hot summer

=o
Point for me I guess.

yehp.. at least billy boy has good deritive sense

Okay, new riddle:

Before I came, confusion abounded.
I'm late, I'm late was frequently sounded.

I'm not average, but was based on a mean.
My size, in theory, is constant: fifteen.

I'm two dozen steps, again in theory.
But walk my length and you'd get weary.

I take half and quarter steps at times.
In reality, I don't follow the lines.

I shrink to nothing in two cold extremes.
Over a thousand miles wide in the betweens.

What am I?

^ a number line?
