Boating New Zealand - Innovision 707 Explorer Split Chine Hull

“Anyone who has overnighted on a boat knows the problem of ‘chine slap,’ which afflicts all boat types with a hard chine design.

This enhancement to the hull design has enabled Innovision to eliminate the point where the chine crosses the waterline, thereby removing the source of the noise rather than trying to deal with it afterwards. By splitting the chine into two parts – one that runs above the waterline, and one below; the new design eliminates the primary source of this slapping sound.

”The above-water chine comes into play in rougher water, providing lift and improving handling at speed as well as reducing spray. At the same time, the below-waterline chine runs into a planing strake towards the stern, providing stability and enhanced ride quality. And the end result is a quieter hull, both at speed and at rest, with improved performance and smoother handling, including in a beam sea..”
