Protect Manatees through Propeller Guard Mandates

Introduction: We are calling on the appropriate authorities to mandate the use of propeller guards on all recreational and commercial vessels in waters where manatees are present. Propeller strikes are one of the leading causes of injury and death for manatees, a species already facing numerous threats to its survival. By adopting propeller guards, we can significantly reduce the risk of these tragic collisions and ensure the long-term protection of these gentle marine mammals.
Background: Manatees, also known as sea cows, are slow-moving herbivores that live in shallow coastal waters, rivers, and estuaries. Despite their peaceful nature, manatees are often in danger of being struck by boat propellers. According to the Florida Fish and Wildlife Conservation Commission (FWC), over the past decade, nearly 25% of all manatee deaths in Florida were attributed to watercraft collisions, with propeller strikes being one of the most common causes.

The Florida manatee population is listed as threatened under the Endangered Species Act, and the need for further protection is urgent. With propeller guards, we can protect these creatures without hindering the boating industry.

Evidence and Data Supporting the Petition:

Impact of Propeller Strikes on Manatees: Manatees are particularly vulnerable to propeller strikes due to their slow-moving nature and limited ability to evade fast-moving vessels. These strikes can cause severe injuries, resulting in traumatic amputations, broken bones, and even death. In many cases, manatees that survive propeller collisions suffer permanent damage that affects their ability to survive in the wild.

The Effectiveness of Propeller Guards: Studies have shown that propeller guards can significantly reduce the risk of injury to manatees and other marine life. Research conducted by the U.S. Coast Guard and marine biology organizations has demonstrated that propeller guards are effective at preventing direct contact between propellers and large marine animals like manatees. Furthermore, contrary to past beliefs, there is no evidence that propeller guards negatively impact vessel motor performance. Modern propeller guard designs do not significantly reduce engine efficiency or fuel consumption, making them a practical and viable solution.

Widespread Use and Support for Propeller Guards: Propeller guards are already being used by a number of boat owners and operators, particularly in areas known for manatee populations. According to a survey conducted by the Florida Fish and Wildlife Conservation Commission (FWC), approximately 40% of boaters in manatee-prone regions have voluntarily installed propeller guards on their vessels. This growing number of responsible boaters demonstrates that the use of propeller guards is not only feasible but supported by the boating community.

Addressing the Misconception: There has been a longstanding belief that propeller guards negatively affect a vessel’s motor performance by reducing speed or maneuverability. However, recent technological advancements in propeller guard design have debunked this myth. Modern guards are designed to provide effective protection without compromising boat performance. Testing has shown that vessels with properly fitted guards can maintain optimal speed and fuel efficiency, with no measurable impact on the motor or propeller function.

Why Propeller Guards Are the Solution: By mandating propeller guards, we can prevent unnecessary injuries and deaths of manatees, creating safer waters for these majestic creatures. There is no reason why we should jeopardize the safety of manatees when effective solutions are available that do not compromise boating activities. The installation of propeller guards is a simple and efficient way to reduce harm to marine life while maintaining the integrity of the boating experience.

Conclusion: The adoption of propeller guards is a necessary and practical step towards ensuring the protection of manatees and other marine wildlife. By mandating their use in key areas, we can reduce the risk of boat collisions and protect these species for future generations. We urge all responsible stakeholders—government bodies, conservation groups, and boaters—to support this initiative for the greater good of our environment and its wildlife.
