I installed electric propulsion in BIANKA for several reasons. One was because my diesel engine died. Two because I spent a good amount trying to get it running again. I began looking at alternatives to having a diesel. Diesel works well where it is worked hard. On a sailboat where most people use the engine to primarily get into or out of the harbor is not the best way to use it. Installed on a trawler is a much better match. So diesels tend to rust out before they wear out or fail at some point when you least expect it. Hopefully in some location  where you can get help and parts.  Another thing about electric propulsion is the ability of it to regen i.e. recharge the battery bank when the boat reaches a certain speed under sail. I thought for the first few years  that my system was not capable of regen but, then one day I discovered that it did. Hybrid Marine has a nice video of how regen works.  The boat in question is a hybrid design and still has a diesel engine. Which would mean the engine might be used even less than in a normal engine setup. But, you still have all the maintenance issues involved with having a diesel installed. But, for those not quite ready to make the leap to a pure electric propulsion system it is an option. Anyway this video is a good primer on the regen aspects of electric propulsion.
