On several other forums recently there have been some discussions of this new generation of Diesel-Electric propulsions. I made an attempt to keep abreast of this subject, and I offer these reference website discussions to anyone wishing to know more about the subject First here are some forum discussions that have appeared on the BoatDesign and Yachtforums sites...lots of good discussions: <http://boatdesign.net/forums/showthread.php?t=9310> <http://boatdesign.net/forums/showthread.php?t=676> <http://tinyurl.com/ysrp6e> But the most highly regarded reference would be the excellent series of articles written by Nigel Calder and Graeme Hawksley for the magazine Professional BoatBuilder. I believe you can access a digital version of these articles here: <http://www.proboat.com/digital_issues.html> You would look at Issue #107, June/July 07 Hybrid Marine Power Pt1 Issue #108, Aug/Sept 07 Hybrid Marine Power Pt2 Issue #109, Oct/Nov 07 Beyond Efficiency Criteria Alone There was also a really good article back in Issue #92, Dec/Jan 05, Diesel-Electric Technology, that I have as a PDF file should you want to see it.
