EBOOK – Giải pháp khắc phục sự cố điện – điện tử trong kỹ thuật hàng hải – Tài liệu hướng dẫn cho thuyền viên và kỹ thuật viên biển (Ed Sherman) – 236 Trang.
In 1996 I had the good sense to enroll in a course on diesel maintenance at New England Institute of Technology; that much I can take credit for. What I can’t take credit for was my exquisite good luck at landing in a class taught by Ed Sherman. It only slowly dawned on me that I was in the presence of one of the country’s great teachers and communicators of marine technology. What I knew immediately, though, was that I was getting my money’s worth.
In the intervening years Ed has moved on to the American Boat and Yacht Council, where he teaches the teachers on boat technology, and for nearly a decade now, he’s brought his incomparable teaching into Cruising World’s pages to thebene fit of us all.
You hold in your hand a fine example of his teaching. As our boats have grown more complex, truly competent skippers are part systems operators as well as navigators and boat handlers. Consequently, the line between recreational boaters and technicians has blurred.
Advanced Marine Electrics and Electronics Troubleshootingmay aim at the professional technician and it hits that target squarely but for the dedicated boat owner who really wants to be self-sufficient, this book provides the guidance to solve the most vexing problems in electrical and electronic systems. If you’re like me and you’re serious about wanting to understand all the details that make up today’s boats, you’ll find more than ample payback for every moment spent in Ed Sherman’s company. You’ll certainly come away smarter.
