[Electric Boats] Possible C27 conversion

 

Hi All,
I joined a few weeks back and have been pouring through postings and searching the internet. Great resource.
In February I bought a Catalina 27 sailboat (not my first and probably not my last) with an Atomic 4 and have been repairing and updating as needed. The boat will be sailed in the mid south on a lake/river so will not be required to travel more than a few miles if the wind dies. I believe this would be a good candidate for electric conversion, not to mention my dislike of gasoline.
If I do a conversion in the future I will probably do it myself. I have been thinking of the Mars brushless motor and Sevcon controller offered from numerous vendors vs a Etek brushed or other brand and Alltrax or Curtis controllers.
Connection to the prop shaft would either be belt reduction or gear reduction.
Would it not be prudent to use a brushed motor so in case of controller failure and no spare available one could limp back to the slip by direct connection to less voltage?
I'm kind of undecided on which path to take. Also I'm no stranger to electrical/electronics as my degree was in electronics and I dabble in electric RC helicopters.

One thing I would like to see is follow up from owners of previous installations on performance and longevity of the systems.
Thanks for your thoughts
Doug
