JUNE 20, 2025: Rhode Island’s picturesque waterways, with their scenic coastal beauty and vibrant boating culture, are integral to the state’s recreational identity. However, the freedom to enjoy these waters comes with the responsibility to operate vessels safely. Boating Under the Influence (BUI) poses a significant safety risk, and the Rhode Island Environmental Police work diligently to enforce BUI laws, ensuring the safety of boaters and others on the water. A key component of these efforts is the integration of the Seated Standardized Field Sobriety Test (SFST) battery.

Rhode Island’s waterways, including Narragansett Bay and the state’s coastal and inland lakes and rivers, attract thousands of boaters annually, making BUI monitoring critical. Alcohol impairs a boater’s ability to navigate, make quick decisions and react to changing conditions. The state’s Environmental Police enforce BUI laws, which prohibit operating a vessel with a blood alcohol concentration (BAC) of 0.08% or higher, aligning with the legal limit for driving a motor vehicle.
The Rhode Island Environmental Police play a pivotal role in upholding these laws. Beyond boating regulations, their jurisdiction includes protecting the state’s natural resources, such as marine ecosystems, and enforcing laws in state parks, beaches and campgrounds. Officers receive specialized training in boating safety and criminal law enforcement.
Enforcing BUI laws requires a methodical approach. Officers patrol waterways, respond to public complaints and remain vigilant during events like regattas or other gatherings where alcohol consumption is common. Assessing impairment on the water presents unique challenges, such as waves, boat movement and wind conditions, complicating traditional sobriety testing. The Seated SFST battery addresses these challenges effectively.
Seated SFST Battery: An Innovative Approach to Testing Impairment
The Seated SFST battery adapts the traditional Standardized Field Sobriety Tests (SFST) used to detect impairment in drivers. The standard SFST includes the Horizontal Gaze Nystagmus (HGN), Walk and Turn (WAT) and One-Leg Stand (OLS) tests. Performing these tests on a moving boat is impractical and unsafe. The Seated SFST battery, adopted by the Rhode Island Environmental Police, allows officers to assess impairment while the boater remains seated, accounting for the vessel’s motion.
The Seated SFST battery includes modified versions of the HGN, WAT and OLS tests, tailored for seated execution. For example, the HGN test involves tracking an object with the eyes while seated. The WAT and OLS tests are adapted to assess coordination and balance without requiring the individual to stand or walk on unstable surfaces.
These modifications enable officers to accurately evaluate impairment under challenging conditions. By observing an individual’s ability to maintain balance, follow instructions and perform coordinated movements, officers can determine whether alcohol or drugs impair the operator’s ability to safely navigate the vessel.

The enforcement of BUI laws, supported by the Seated SFST battery, is vital for reducing incidents and fatalities on Rhode Island’s waterways. Boating incidents involving alcohol or drugs can lead to property damage, serious injury or death. The Environmental Police’s efforts protect boaters, passengers and others on the water.
Rhode Island’s commitment to BUI enforcement also serves as a deterrent. By demonstrating that BUI laws are strictly enforced and equipped with effective tools like the Seated SFST battery, the state aims to reduce impaired boating. Public education on BUI dangers, combined with robust enforcement, raises awareness of the consequences of operating a vessel under the influence.
The Seated SFST battery enhances the credibility and reliability of BUI enforcement. Previously, the lack of standardized testing procedures for impaired boating posed challenges, but the Seated SFST battery provides evidence that can be effectively presented in court, supporting convictions and the broader goal of reducing impaired boating.
Boating Under the Influence remains a significant concern on Rhode Island’s waterways, and the Environmental Police are at the forefront of addressing this issue. By enforcing BUI laws and utilizing innovative tools like the Seated SFST battery, officers enhance safety for all who enjoy the state’s boating opportunities. Rhode Island’s commitment to effective enforcement ensures its waterways remain safe and enjoyable, preserving its reputation as a premier boating destination.
