This study aimed to determine the concepts learned in Navigation and Seamanship as well as the level of satisfaction of students’ in using the training ship in terms of food, accommodation, readiness of venue, quantity of equipment, activities, speakers, and ships’ crew. The respondents of this study were the 129 students of JBLFMU-Arevalo. They were selected through stratified and cluster sampling. A questionnaire was sent to the respondents through e-mail and Facebook messenger to gather the data. The comments of the students were classified according to themes. For BSMT 1 – Familiarization and Ship Tour, in Navigation, the themes are learning the ship nomenclature and manipulating the different navigational equipment onboard, inculcating skills to plan and manage a ship for safety voyage, employing the concepts learned about the various ship positioning to arrive at the port or point of destination, and refining the importance of learning the qualities of a competent navigator. In Seamanship, the themes are enhancing concepts learned about the importance of prioritizing safety on board and learning the International Maritime Law, learning the important purposes and uses of the different navigational equipment on board, improving skills on proper operation of the ship, and uplifting the duties and responsibilities of officers and crew members on board. For BSMT 2, Port and Anchor Watch, in Navigation, the themes are, learning the uses and importance of the different navigational equipment on board, different types of navigation use to navigate accurately, employing the concepts learned about the various ship positioning to arrive at the port or point of destination, uplifting the duties and responsibilities of officers and crew members on board, and defining navigation for watercraft. In Seamanship, the themes are learning about anchor operations, familiarizing different parts of the ship, integrating seamanship skills in navigation, enhancing concepts learned about the importance of prioritizing safety on board, learning mooring operation, and definition of seamanship. For BSMT 3, Navigational Trip, in Navigation, the theme is learning the different navigational equipment on board and for Seamanship, improving seamanship skills. Having different themes for every year level indicates that the students have actually learned various knowledge about Navigation and Seamanship during their stay onboard the training ship. For the students’ level of satisfaction, the grand mean is described as “High”. This means that some aspects are good in terms of food, accommodation, venue, quantity of equipment, activities, speakers, and ships’ crew. This study concludes that the concepts learned by students’ in Navigation and Seamanship varies in each activity. Furthermore, the students were highly satisfied in using the training ship’s amenities in terms of food, accommodation, readiness of venue, quantity of equipment, activities, speakers, and ships’ crew. The researchers recommend another follow-up study to include respondents from other units as well and some other non - JBLFMU/JBLCF students utilizing the training ship to further validate the results, reduce the number of students participating in every activity to optimum to maximize the outcome intended for each activity, and finally, create a multiple choice questionnaire to assess better the concepts learned and to be given personally to the respondents.

The main goal of this task was synthesis of the multivariable regulator for precise steering of the real, training ship. However such object is strongly nonlinear and its characteristics depends on current work conditions. Therefore one of possible ways to build a proper ship's controller can be the robust control theory approach. It enables the introduction of the effects of the modeling errors, unknown nonlinearities, unawareness of the particular object phenomena into the controller synthesis process. First part of the paper describes the meaning of the weighting functions in the system, the conditions for computing of the H∞ controller and the parametric and nonparametric uncertainties. The next part presents the requirements which should be fulfilled by regulator to the robust one and it describes the way how to calculate the multivariable robust controller via D-K iteration. In the last part of the paper exemplary results of the steering process from simulation and the real-time illustrates the control quality of the obtained closed-loop system.

The main goal of this task was the synthesis of the regulator for precise steering of the real, training ship. One of possible ways to build a proper ship's controller can be the robust control theory approach. First part of the paper describes successively: the shiphandling training boat "Blue Lady", nonlinear simulation model of the vessel and the MIMO state ship model, identified for robust regulator synthesis after experiments on the presented simulation model. Second part of the paper presents: the way to calculate the multivariable controller via D-K iteration, final regulator and exemplary results of the real-time steering for verification of obtained closed-loop system.
