Ships suffer from small punctures that can cause severe damage, as they are unable to return to shore.

By applying the conceptual role of sap and its protection methods to the hulls of boats we can greatly increase the likelihood of boats making it back to shore. It can also allow ships to continue on their route without making an emergency stop which will greatly increase fuel efficiency.

This is a precedent for the top cover we used in our final design. It allows the water sensors to be protected so they don't get damaged, and it completes the full look of a boat. This addition was mostly astehetic.

Other feedback we recieved during mid-reviews was to make different sections (Ex. Section A) so that when water was detected, it would be easier for the captain to find and locate the issue. In our final design, we split up the area with the cement into four sections each with it's own water sensor and LED. We coded it so that when water was detected in one of the sensors, the LED would turn on.
