CHINE QUAD

The idea of this board came from seeking more planing area to catch waves and gain speed without the board feeling too wide in steep surf; essentially trying to find a medium between small surf and larger surf. A middle ground for everyday surfing - something I was excited to ride by looking at, giving myself the chance to enjoy all surf days.

The plan shape is a mix of wider stubby/fish curves for rail line and shortboard curves for release, the rocker is in between a flatter fish type for speed and an 80’s shortboard curve for lift and pop.

There is a deep single concave that enters the bottom half which meets a flat around the wide point where a gradual double concave follows all the way out off the tail. The quad fin setup is aligned with the contours, it is quick to accelerate on rail, lifting off the double concave and releasing water off the boxed rails around the fins - this makes it quick to get going in short punchy beach breaks and also lift down the line on clean waves.

The “chine” is referring to the bevelled bottom rail. Its advantage is being able to hide width and thickness in the board, the chine makes the wider thicker board roll over rail to rail with ease. Essentially the chine is a touch of vee on the rail. It’s an old design - and used in many boards still. This is my interpretation. the ‘chine’ runs through the centre of the board straightening the plan shape and additionally minimises the wetted surface area of the bottom.

Overall this board has become a favourite - specifically in the ‘fish’ template. Ive rode it in up to 6ft and It wants to go almost anywhere on the wave you hope to get too. I’ve been working on other boards including the ‘chine’ bottom which all have been working really well, anything with width essentially - keeping the same contours and fundamentals the design is morphing. TBC.
