Hi all! I want to prepare properly before taking the Y4 modules. Can anyone recommend suitable literature? I have the syllabuses from MGN 156 (and the updated ones from the MCA website and also the obsolete MIN 208) and I have made printouts of relevant pages of MARPOL, STCW and some M-Notices. But where can I found the "non-regulations" stuff? I have H.D. McGeorge's "Marine Auxiliary Machinery" which I personally think is very unstructured and actually not usable at all. Any other recommendations? Pounder's "Marine Diesel Engines and Gas Turbines" seems to be an excellent book. Is it worth buying or is it too much tankers etc? For electricity I have "The Marine Electrical and Electronics Bible" by John C. Payne and "Boatowner's Illustrated Handbook of Wiring" by Charlie Wing but they are more for smaller boats. I also have "Stamfords Fault Finding Manual" which is very good but of course a bit specialised. Reed's Engineering Series "Basic/Advanced Electrotechnology for Engineers" seems to be a bit too technical. What I lack is something that applies to yacht's electrical systems. Any hints are greatly appreciated!
