JB12 - 12m Highspeed GRP catamaran


The JALBOOT12 is the development of the EM16, and builds on the considerable experience and proven success of this boat adding to the companies’ development through the last 30 years. The existing range of 10m, 12m and 14m designs has given excellent service in a wide variety of uses and environments. 

• 12.1 meter hull built in a multiple piece mould to ensure exceptional strength and infused reliability. 
• our specialist composite construction is state-of-the-art and guarantees maximum quality control. 
• All our designs benefit from construction specifications, layup, scantlings and engineering details approval by any Certification Authorities. 
• Our designs enjoy a complete audit history of essential criteria and come with a detailed technical file. 

Our designs offer legendary class safety, stability, speed and seaworthiness. Our catamaran hulls have low drag so fuel economy is superior to that of similar sized mono-hulls at similar speeds. Maneuverability, both at low and high speed and in deep or shallow water, is also exceptional. 

The JB12 is finished in a white gel-coat and crafted from GRP using an infusion process. A range of By-axel and Quad-axel fiberglass with HD foam as core to optimize a lightweight and strong structure. All bulkheads are laminated in, using “e” – glass.
