Detailed Technology and Design Philosophy

WHAT HAVE WE DONE?

Kona has, believe it or not, become the first company in the industry to analyze one of the most important parameters within stand-up paddling.

Introduction

Kona has, believe it or not, become the first company in the industry to analyze one of the most important parameters within stand-up paddling. Stability has a major impact in the choice of board and we want the customer to find the right board easier than ever before. When introducing the stability number the customer can easily compare boards and find the right one for their ability and needs.

Heat moulding

Heat Moulded technology makes Kona Boards fiber laminate lighter, stronger and tougher than the market Standard, to use heat process you need ecat the material you need and the process are more exact.

Construction

Carbon

The board is designed using an ultra-light CNCed EPS core compressed with a heat moulded carbon fibre laminate. This is a unique technique that creates an extremely light and tough construction that can withstand all the action in a racing environment. The boards epoxy to fibre ratio is carefully controlled by our approved factory’s which give the maximum stiffness to weight ratio. The finish is a light weight paint and clear coat finish for smooth water flow.

Hybrid

The board is designed using an ultra-light CNCed EPS core, compressed with a heat moulded Glass fibre laminate.  This is a unique technique that creates an extremely light and tough construction that can withstand the demands of exploration. The boards epoxy to fibre ratio is carefully controlled by our approved factory’s which give the maximum stiffness to weight ratio.  There is a central Uni directional glass stringer which adds to the stiffness of this board and helps with gliding efficiency. The finish is a light weight paint.

Comparison and Hydrostatics

Applying Naval Architecture principles the stability of the boards can be analysed and simply compared.Using a unique stability number, you can work out what size boards are right for you and use this across all our new boards coming out.Our stability number is a formula that considers all aspects of stability, including the deck position, centre of gravity, volume distribution, width, and weight.

Forward Tracking:

Carefully aligned central channels, combined with a sharp bow help to keep the board in a straight direction, ultimately saving you energy and speed.

Shaping

The shaping utilises the latest in 3D design technology, using subdivision surface modelling, a technique more commonly used in the automotive design industry.

The boards hydrodynamic features have been optimised using advanced hydrostatic computer programs alongside rider input. The underwater surface and shape is designed to reduce drag and add stability.

1. Skin Friction, the boards wetted surface area is at a minimum with its displacement shaped bow and forward areas.

2. Wave Drag, by carefully optimising the volume and rocker line distribution in the board this reduces large changes in the natural pressure field created when the board is travelling through the water and therefore reduces the natural wave drag component.

3. Form Drag, we have added deep central channels in the board to create stability when the rider becomes unbalanced and tips the board by accident. This means that the board can be ridden at a smaller width than they would normally use and therefore reduces the form shape pushing through the water.

Stability:

The board has a been carefully designed to lower the deck area close to the water line, this lowers the riders centre of gravity, therefore creating a more stable board and conserving your energy.

We have included plenty of volume in the nose and tail, this helps keep the boards nose above the water and be able to keep its speed in chop. It also allows the rider to paddle harder as the board is not sensitive to longitudinal weight changes.
