Precision Handling: Lower Units, Mounts, Steering
One of the biggest safety and performance considerations for any high performance boat is high speed handling, and although the hull design is critical to handling, the setup is vital
Boat Weight Dynamics: Move it
In all boats, weight, weight distribution and balance are key to how the boat floats and performs. With performance boats, it can be more complicated because typically performance boats are already light and when a hull travels faster through the water, weight dynamics change.
