Why Wave Piercing Bows
The basic concept of a wave piercing bow is to have the boat go through the wave instead of riding up and then down over the wave. This particular hull design does not have the dynamic buoyancy that you find in most vessels, in other words it does not produce noticeable lift when running, hence keeping the boat flat and smooth through choppy conditions. Therefore, there is reduced stress on the vessel and the crew. This design also has the benefit of reducing the boat’s wave making resistance which means she goes through the water easier, equating to better fuel economy. The wave piercing hull design is in use worldwide by modern passenger and cargo ferry catamarans. The main reason is the boat achieves a higher top speed, smoother ride and much better fuel economy! The Journey 46 is the first production power catamaran using this innovative hull design.
Tim Kernan’s first wave piercing catamaran was “Water Wizards”, designed for rugged ocean conditions worldwide. This 50’ power cat was built to film ocean sailboat races and needed to be able to have a high turn of speed and be very stable in all conditions.
