Cheoy Lee Shipyard has been owned and operated by the same family for more than a century. As a building and a repair yard at Po Tung Point in Shanghai, Cheoy Lee began producing steam powered craft. After 1936, the business moved to what was then the British territory of Hong Kong.
By the mid 1950’s, the shipyard diversified into the production of teak sailing and motor yachts and the success of the newly formed pleasure craft division was soon apparent. By the mid 1960’s, a majority of the company’s production was pleasure craft, with large numbers being exported to the United States.
During the 1960’s, Cheoy Lee was one of the pioneers in the development, testing and use of fiberglass construction techniques and a forerunner in the use of GRP/Foam sandwich technology in the marine field.
In 1977, Cheoy Lee built a 130′ motor sailer, the world’s largest GRP vessel of the time.
Other than on a strictly custom basis, Cheoy Lee stopped building sailing yachts in 1990 to concentrate on large Motor Yachts.
To accommodate this expansion, the company moved to a new purpose-built, state-of-the-art shipyard facility in mainland China. electric sailboat conversion.

Navigating the Future: How Marine Diesel Engines are Revolutionizing Boating Efficiency and Emissions
In the ever-evolving realm of marine technology, marine diesel engines are at the forefront of transforming boating efficiency and emissions. These engines are paving the way for a more sustainable future by introducing groundbreaking advancements in engine efficiency and emissions reduction. This shift not only promises enhanced reliability but also aligns with the growing demand for eco-friendly solutions in both recreational boating and commercial boating sectors. Through expert insights from 805 Marine Mechanic, this exploration will delve into the benefits of upgrading to newer models, highlighting the latest boating innovations that are setting new standards in marine performance and sustainability.
Advancements in Marine Diesel Engines
Innovations in Engine Efficiency
Marine diesel engines have seen remarkable innovations aimed at enhancing engine efficiency. At the heart of these developments is the integration of advanced technologies such as turbocharging and electronic fuel injection. Turbocharging allows engines to deliver more power without increasing fuel consumption, while electronic fuel injection ensures optimal fuel delivery, reducing waste and boosting performance. These technologies work in tandem to minimize energy loss and maximize output. Furthermore, precision engineering and lightweight materials contribute to reducing the overall weight of engines, thereby improving fuel economy. This focus on efficiency not only lowers operational costs for boaters but also aligns with environmental goals by curbing fuel consumption. As these innovations continue to evolve, they are setting new benchmarks for what can be achieved in both recreational boating and commercial applications. This push towards greater efficiency is a testament to the marine industry’s commitment to sustainable progress.
Breakthroughs in Emissions Reduction
The marine industry is making significant strides in emissions reduction through groundbreaking advancements in marine diesel engines. A major breakthrough is the incorporation of selective catalytic reduction (SCR) systems. These systems effectively reduce nitrogen oxide emissions by utilizing a urea-based solution, converting harmful pollutants into harmless nitrogen and water vapor. Additionally, the use of particulate filters has become more prevalent, trapping soot and particulate matter before they are released into the atmosphere. Engine manufacturers are also focusing on optimizing combustion processes to minimize unburned hydrocarbons and carbon monoxide emissions. These innovations ensure that marine diesel engines meet stringent environmental regulations, which is crucial for both recreational and commercial boating sectors. By adopting these technologies, the marine industry is not only reducing its environmental footprint but also aligning with global efforts to combat air pollution. This commitment to emissions reduction underscores the industry’s dedication to fostering a cleaner and greener marine environment.
Benefits of Upgrading Your Engine
Enhancing Recreational Boating Experience
Upgrading to modern marine diesel engines can significantly enhance the recreational boating experience. Newer engines are designed with cutting-edge technology that offers smoother and quieter operation, making for a more enjoyable journey on the water. Modern engines also provide improved fuel efficiency, allowing boaters to extend their adventures without frequent refueling stops. Additionally, advancements in engine diagnostics provide boaters with real-time performance data, enabling them to monitor and maintain their engines more effectively. This reduces the likelihood of unexpected breakdowns, ensuring more time is spent enjoying the water rather than dealing with mechanical issues. Furthermore, upgraded engines often come with enhanced safety features and improved torque, delivering better handling and maneuverability. These benefits collectively contribute to a more seamless and pleasurable boating experience, making the investment in a new engine a worthwhile consideration for any recreational boater looking to enhance their time on the water.
Commercial Boating Performance Boost
Upgrading marine diesel engines in commercial vessels offers substantial performance enhancements. Modern engines provide increased power output and efficiency, which are crucial for meeting the demanding schedules and heavy workloads typical in commercial operations. With improved fuel economy, operators can significantly reduce operating costs, making their businesses more profitable and sustainable. Additionally, newer engines are built with durability and reliability in mind, reducing downtime and maintenance expenses. Advanced engine control systems offer precise monitoring and management capabilities, allowing for optimal performance under varying conditions. This ensures that vessels can maintain speed and power, even when carrying large loads or navigating challenging waters. Enhanced performance translates to faster turnaround times and increased productivity, enabling commercial operations to stay competitive in the industry. Investing in engine upgrades not only boosts vessel performance but also aligns with environmental regulations, positioning businesses as responsible stewards of the marine environment.
