As part of the continuous effort to validate and improve our numerical prediction capabilities, a validation study was performed that focuses on planing hulls. Series 62 hull model number 4667-1 was selected for the test, and CFD simulations at 17 speeds were carried out. The speed range spans the resistance hump, with displacement volume-based Froude number ranging from 1 to 6. 

Graph below shows the comparison of experimental against CFD results for resistance, sinkage (CoG rise) and dynamic trim. In summary, the average differences between CFD and experimental results are found to be as follows:

• Total resistance: 2.6 %,
• Dynamic sinkage (CoG rise): 8.1 mm,
• Dynamic trim: 0.1 degree.
