   The kayak was invented by Arctic peoples thousands of years ago, sealed with animal skin to stay watertight.

3. A small recreational sailboat 9.4 m

   Modern sails work like vertical wings, generating lift that lets boats sail faster than the wind itself.

   The bridge's 'International Orange' colour was chosen partly because it stays visible in San Francisco's thick fog.
