## Abstract
Abstract The numerous stages and eaquipment used to measure the dimensions of a fishing boat make this method less efficient. The aim of this research was to compare the results of measuring the horizontal dimensions of fishing boat hulls using conventional methods and drones with different flight path variations. Data collection was performed using drones with aerial photography techniques. The 3Dsurvey pilot software was used to create a flight path pattern of 0 0 and 90 0 at an altitude of 40 m with an overlap of 80%. Aerial photo image processing was carried out using Agisoft metashape software with medium settings to align photos, dense clouds, and tiled models. From 4 different locations, there were 32 fishing boats were measured from four different locations. The results showed that the dimensional average difference values for LoA were 2.78 cm and Bmax was 1.63 cm with the 90 0 flight path pattern. The 0 0 flight path pattern shows that the dimensional average difference values of the LoA was 3.22 cm and Bmax were 3.92 cm. A completely randomized block design test stated that both treatment and block had an influence on the LoA. The treatment had no influence on the Bmax, but the block had an influence. Tukey’s test results indicated that K1 was not significantly different from K2 on the LoA. K0, K1, and K2 were not significantly different for the Bmax. This technique can be applied as an alternative method to measur the horizontal dimensions of fishing boat hulls in large quantities.
