Figure 3.9 Interceptor [13]
Interceptors can be chosen over trim tabs due to many reasons. These reasons vary from low
drag force to easy maintenance or from low cost to lightness. Interceptors are significantly
lighter than trim tabs and minimizing the weight is essential for high speed crafts. [3]
Table 3.1 was provided for a better understanding of the comparison between trim tabs and
interceptors.
Table 3.1 Comparison between Trim Tabs and Interceptors [14]
Parameter Trim Tab Interceptor
Maximum Lift Developed for Ride Control Significantly Higher Lower
Hull Resistance at Optimum Trim Same
Weight Same Lower
Installation Higher Simpler
Cost Harder Lower
Maintenance Higher Simpler
Damage from Floating Objects Harder
Established User Base Minimal Risk Higher Risk
Large Smaller
Below, Figure 3.10 Drag force comparison [15] shows drag force comparison for both options.
