To what level of detail should naval architects be evaluating propeller performance? Donald MacPherson, Technical Director of HydroComp Inc, puts the case for more active engagement


In the design of many vessels, naval architects are selling speed. Or so one would think.

Actually, they are selling speed “with conditions”. Those conditions are many, but a few of the major objectives and constraints are to deliver speed with…

• high efficiency and minimal fuel consumption.
• emissions within regulated limits.
• acceptable cavitation to avoid erosion.
• noise and vibration within habitable limits.
• consideration of off-design dynamic power demands.

Read more about why everyone benefits when the naval architect is involved in the specification and design of the propeller.
