Windracers Experiment

 Monday 14 September 2020

This week in Science, Kyra-Lee, Lily-Ray and I are Researching and designing a windracer. A windracer is a small, free-flying staysail for super light air. It's tall and thin. It's freestanding, so it's not attached to the headstay. The tack attaches to a deck pad-eye. Use your spinnakers' halyard to raise it and tension the luff.

After researching different types of Sails, we decided to make the 'Storm Jib' sail. The Storm Jib sail is good for strong weather and we will need something like this for the harsh wind provided from the wind blower.

On the second day, we built the first model of our windracers using newspaper, string and tape. We tried to make a replica of the plan.

On the third day, we will be testings our windracers to see if we need any changes. We then painted our sail with red, white and black stripes. 

On the forth day, we tested our windracers against the rest of the class. The results helped us get an idea of the changes we would need to make to have our windracer move the furthest. The changes we are making is adding extra support to the sail, so that it could catch more air and not have the windracer toppling over.

On the fifth day we made the changes to our windracers. We added more newspaper and stabilised the sail.

On the sixth day we had the final race against the rest of the class. Our windracer was in 4th place.

The changes that we made didn't help us as much as we expected, but it did add stability. 

The best thing about this project is the we came 4th and we had so much fun.
