This is really just a simple rendition, but everyone should recognize it easily.

Here’s how to draw Noah’s famous ark:

Start by drawing the cabin as a fat rectangle. Don’t worry about an exact measurement; just try to keep it somewhere between a square and twice as wide as it is tall. | |

Cut the rectangle in two horizontally. | |

Extend the line you just made a little ways past both sides of the rectangle. Finish the roof by connecting the ends of the line to the top corners. | |

Make a door to the cabin by adding a rectangle somewhere towards the middle of the bottom rectangle. | |

Make sweeping arcs from the bottom corners to start the bow. The ends of these lines should be even and a little bit higher than the corners they start from. | |

Use another set of long shallow arcs going from the ends of the arcs you just made down a little farther than the cabin is tall to finish the ship itself. | |

Add rolling waves at the bottom. | |

Tidy up the lines a bit and you’ve finished your ark. |
