IALA recommendations - Opis:
- The use of daymark shapes for leading lines include its visual shape and symbol, to aid sailors who need to navigate safely through a marked narrow channel. The shapes which are currently used are rectangles, diamonds, and triangles. However, there is not much information on which shape is the most effective for navigational referencing. Therefore, the main objective of this research is to determine the most effective shape for a leading line daymark. The Kemaman Port was used as an area of interest to model the three-dimensional simulation. The size and height of the leading line daymark was calculated based on the dimensions of the navigational channel obtained from the Kemaman Port navigation chart. The simulation for different shapes of the leading mark in the same area was developed using a three-dimensional software. Experts were engaged to evaluate the effectiveness of each daymark shape across the maximum and minimum distances during the simulation run. Results showed that the diamond shape daymark was relatively better identified and used as reference, compared to other shapes in the same range due to its relatively larger surface area. Therefore, the study objective was achieved, and the results can be used to improve marine navigation safety.
