Bilge pumps are designed to pump out excess water accumulated in the bottom of a boat, otherwise known as the bilge. When excessive volumes of water are detected, bilge pumps often have an embedded alarm system to alert the crew of a possible leak. On-board alarm systems can also indicate a failure of the pump itself, which can occur due to many environmental factors depending on the type of pump. Although bilge pumps can become critical life-saving equipment when a crew is underway, they also play a large role in preventing a boat from sinking at the dock. When left unattended, boats remain subjected to many of the same environmental stresses and equipment failures that would lead it to sink while underway. In fact, a boat is four times more likely to sink while at the pier as a result of the crew not knowing until it’s too late. To solve this problem, we have teamed up with the Hatfield Marine Science Center to develop a battery powered maritime vessel alert system (MVAS) capable of sending an SMS text message to notify a boat owner as soon as high water levels are detected in the bilge. This early warning system will give boat owners a chance to save their boat from sinking before it becomes too late. Our system is intended for owner-operators who may leave their boat unattended for weeks or even months at a time. It will provide an additional layer of protection by alerting the owner of a potential leak in time to still save the vessel. Key technologies implemented in our design include our transceiver module, cloud and webpage support, and battery power. These three work in conjunction to provide the user with remote protection for an extended period of time with minimal maintenance required. Future design considerations include integrating the battery modules onto the main PCB, designing an injection-molded enclosure that can be produced at scale, and including dip switches on the PCB to allow the user to select between pre-defined modes of operation.
