The Hyde Drift Boat Company is developing and engineering a design to allow the waters unrestricted movement under your hull in a laminar flow. This is important because natural friction or "drag" is created between the water and any boat hull. Laminar flow conditions produce less drag than turbulent flowconditions.
Maintaining a laminar flow under your boat is mandatory to reduce drag, and ultimately makes it easier and safer for you to row and maneuver your boat. The following is an overview of the proven technology and engineering practices we use at Hyde Drift Boats to promote laminar flow under our boats and reduce the drag.
Tunnels are used on many power boats and are located at the rear of the boat or the waters exit point. One key detail to remember is that the water exit point on a drift boat is actually the front of the boat (the bow). While the concept of a tunnel works well for power boats, it only further disrupts water flow when used on a drift boat (see a drift boat with tunnel ).
Hyde uses a flat, rigid bottoms on all Hyde Drift Boats. As the water flows under a drift boat it creates a buoyancy force pushing the boat upward. Drift boats with flexible bottoms can turn laminar flow into turbulent flow by the up and down movement of the boat hull. You might even compare that flexible bottom to a wave tank where waves and turbulence are intentionally created by moving a panel back and forth. That up and down motion also creates fatigue to the resins used in the boat which in turn result in a shorter life of the boat structure. Since the goal of a drift boat is to createminimal disruption to the water flow, keeping the boat bottom firm and rigid is important in creating less drag and improving the overall performance of the boat.
The importance of a rigid hull in any boat is best explained by thinking of rigid hulls in power boats. Just imagine a power boat with a flexible hull and the drag or instability that it would create. The principle is the same, rigid hulls make better boats be they power boats or drift boats. This is especially true when the hull is the floor as is the case with some drift boats. www.hydeoutdoors.com
