Barriers & booms | the second is 22 meters long, positioned parallel
but closer to the shore-based structure. Wall plates are installed at specific locations to support these downstream booms. One wall plate is placed above the high-water level on the wall to ensure the boom is in line with the 670-meter mark. Another wall plate is positioned near a fish pass, also at the 670-meter mark near a jump wall. A last wall plate is installed on top of the spillway for the boom to be in line with the 670-meter mark. Two ground anchors are indicated in the plan, both for the upstream boom. The locations of these ground anchors were to be finalized based on the actual site conditions, ensuring that they remain above the high-water level.

Clunie Dam Project 2024 The Clunie Dam, located at the eastern end of Loch Tummel in Perth & Kinross, Scotland, is a critical part of the Tummel Hydro-Electric Power Scheme. By raising the loch’s water level by 5 meters, it provides the necessary water head for the Clunie Power Station, which lies 3 kilometers to the east and is supplied through an underground aqueduct. Given the proximity of the Loch Tummel Sailing Club upstream from the dam, safety is paramount. The club is heavily used for various water-based activities, including sailing lessons, kayaking,
paddleboarding, and events in collaboration with the Scottish Coastal Rowing Association. Its fleet includes dinghies, catamarans, and small keelboats. To ensure the safety of club members and the
broader community, Bolina Watercraft Safety Booms will be installed within the coming weeks. As the club continues to grow, the installation of the safety booms is critical in protecting both enthusiasts and casual users of the Loch, reinforcing the importance of proactive safety measures in such a dynamic recreational environment.
Winter performance As winter approaches, it is crucial to evaluate
the performance of Bolina Watercraft Safety Booms in challenging conditions. These booms are specifically engineered to withstand severe winter conditions, including harsh storms and freezing temperatures, without compromising their protective function. The booms are known for their durability and reliability, particularly in cold-weather environments. Their superior performance in arctic winters and storm-prone regions is attributed to the innovative materials and thoughtful engineering behind their design.
Safety boom features & benefits Enhanced float molding process Key to the booms’ durability is the enhanced float molding process. Unlike standard floats, which typically measure 4 millimeters in thickness, Bolina Watercraft Safety Booms use a high quantity of powder during molding to create 6-millimeter- thick floats. This added thickness makes the floats more resilient to freezing temperatures and better equipped to endure the challenges posed by winter climates.
Foam-filled floats for increased reliability In addition to their thickness, the booms feature foam-filled floats, unlike air-filled counterparts commonly used by competitors. This foam-filled design ensures that the booms remain virtually unsinkable, even in extreme conditions where freezing temperatures might cause air-filled floats to crack or allow water to penetrate and freeze inside. By preventing water ingress, the floats maintain their integrity, protecting the boom’s functionality even in the most frigid environments.
High-quality galvanized shackles for secure installation The booms are also secured with high-quality galvanized shackles, providing additional weather resistance and ensuring the entire system remains operational despite exposure to ice and heavy winds. This meticulous attention to material quality and weatherproofing guarantees that the booms can withstand prolonged exposure to winter elements.
Proven performance in extreme climates Over the past two decades, Bolina Watercraft Safety Booms have consistently proven their durability in cold-weather climates across Northern Europe, the UK, the US, and Canada. Their performance in regions like the Netherlands’ De Biesbosch National
