The Bilge: The Seasickness Solution

I have been on boats at Lake of the Ozarks and on the ocean in Florida.The boats rock back and forth, and that makes my mom very seasick sometimes. I wanted to know more to prevent seasickness and keep my mom happy. In this experiment, I learned about bilge keels and their impact on boats. I wondered ‘how do bilge keels reduce seasickness?’ I chose to test the boat without a bilge keel to first determine how much waves impact a boat. Then, I added a 16cm bilge keel to my model boat and counted the number of oscillations and time. After I completed that test, I tried an 8 cm bilge keel on my model boat and repeated my observations. I also wanted to understand how the bilge keel works in still water or a lake environment, as well as in a waterfall or ocean environment. So, I tested the boat with each bilge keel in each environment. I learned that bilge keels do reduce seasickness and stabilize the boat. The smaller bilge keel was the best. I met my objective, so now I can share my results with people like my mom. Boats with smaller keels are more stable and will help reduce effects on the body like seasickness.

  1. Excellent research question and I think your experimental design was fantastic! Your unit of measure (oscillations) was a very clever way to evaluate the impact of the bilge keels. Well done!
