This concept paper described the process of bridging the gaps in one of the methods for determining wheel over point (WOP). WOP is a marking made on charted courses to indicate a point at which a ship should change course. Identifying WOP is vital to avoid the vessel overshooting the planned track. One method for determining WOP is the advanced transfer technique. However, two issues were identified while reviewing this technique. Therefore, an improved mathematical model could be developed to overcome these problems. A manoeuvring analysis using a ship simulator will be performed to test the developed mathematical model's efficacy. The data obtained from the simulation study can be validated further by its adherence to the cross track limit, reduction in percentage change, and using IBM SPSS for the Mann-Whitney U test. The developed mathematical model is expectantly capable of producing a better track-keeping function and suitable for use onboard a cargo ship. The mathematical model also could be implemented as an algorithm in the Electronic Chart Display and Information System to help navigators make more efficient course changes.
