- Some Rate Differentials apply to the characteristics of an individual piece of equipment. For example, if a boat swapped into the Tow has a higher-horsepower engine than the one originally under the contract, a premium might be charged for this boat. This would be handled via a rate differential attached to the boat when it is added to the voyage.
- Another type of Rate Differential could include additional daily charges for traveling west of Corpus Christi or east of New Orleans. This would be handled on the Activity Log - Barging, since these are typically included in the traffic reports provided by the owners.
On the Data Center menu Center menu
