WHY IT MATTERS

Grey market
costs more.

A failed PSC inspection. An OWS that reads non-compliant. A part that doesn't fit. When your vessel is in port and time is the constraint - the premium you pay for genuine RWO parts is nothing compared to the cost of getting it wrong.  
We supply only genuine RWO components. No substitutes. No grey market.
