Chines??

[jslayde1]

Reading the other thread made me remember a question I meant to ask earlier.....what is the purpose of the chines?

I mean, were they just made to screw up the wake?

Good question, I want to know myself. Hoping someone gets ambitious and makes a "VX" wake shaper / swim platform all-in-one with ballast that's glassed onto the transom. Will assist with funding for materials.

Multi-chine hulls allow the cross section of hull exposed to the water to be reduced when the vessel is lifted because of resistance of water in front of the hull. This is known as a planning hull. As a vessel is lifted less of the hull contacts the water and it becomes laterally unstable. This instability allows a hull to pivot along its length, and difficult to stabilize in a high speed turn.

Multiple Chines are valuable on larger craft which operate in rough conditions. The aspects of a multiple chine hull ease the boat into an oncoming wave more slowly absorbing the shock. A single flat surface would transfer all of the wave energy to the hull at one time. Steps of the chine also suppress hull roll and heave by spreading out the impact of waves over a longer period of time.

Chines also improves the amount of time it takes for a hull to get on plane, by way of creating a lifting energy as water flows along the chine. This would be why the chines are much more defined at the bow and fade towards the rear.

Thorough answer...very interesting. I had figured the chines were to help with the ability plane faster, but had not thought much more.

Hopefully the VX will improve the negative impact of the outer chines on the surf wake.
