Mr. Lopez gives us knowledge and information about ship systems that are quite specific and it is difficult to find such detailed and precise literature on the Internet, as well as video lessons. His program will benefit everyone, beginners and people who know this profession will find all the necessary information, knowledge of the systems and the rules by which these systems must work to be safe for us and the ship. I, who have been working for more than 4 years as a marine electronics engineer, also find some important details that help make the job even more professional. Let us support Alvaro to continue his work to make marine systems efficient and safe.

Me. Lopez is by far the best in the business! He has a true understanding of the marine field is with his teaching you will go very far.

There is nothing else that I’ve watched or read on the internet that is as comprehensive and easy to follow as Mr Lopez Classes. He explains complex Marine systems in easy to understand language and demonstrations. As a cruising sailor I find these completely invaluable.
