The California draghead mainly consists of a visor carrier, fixed to the side suction pipe and a pivot mounted self-adjusting visor. A self-adjustable visor with an optimised shape forms an enclosed space directly above the ground. The visor is equipped with knives and ripping teeth to loosen compact soils. Pressure water is used for fluidization of the ground. Wide dragheads are equipped with two independent visors, so that the whole suction area is in close contact to the ground even on uneven ground. The California visor has mechanically adjustable water inlets on top, allowing supply of additional transport water in soft grounds.

This type of draghead is particular suitable for dredging firmly packed and strongly binding types of soil. Due to the modular design a VOSTA LMG California draghead can easily be converted to a VOSTA LMG draghead with a Turbulence visor or a Universal visor.

The California draghead is a welded construction made of structural steel. Knives and teeth can be easily replaced. Wearing parts are made of highly wear resistant material and can be exchanged or armoured by built-up welds. Strong rubber fenders are provided to avoid damage to the ship's hull. A safety joint and shear bolts can optionally be provided to safeguard the draghead from excessive trailing forces.
