Thumbs down Electric Powered Newport 30

I am looking for any experience and advice from the Newport community or other similar sailboats. I am about to start a project of replacing a dead Atomic 4 in my just purchased 79 Newport 30. I have selected a new electric brushless power system from Electric Yachts.
Do you know of anyone who has done a similar re-power. I am looking at going with a 180amp motor, 48v system, providing 9shp to a new three bladed prop. The plan is to install 8 6v Trojan batteries I am expecting to be able to cruise up to 30 miles at 4.5k. longer at slower and less at higher speeds. Solar and wind will also be part of the package.

Hi Mike,

I responded to your other post in the electric sailboat motor thread about your Newport 30 repower.

Something I would talk to Electric Yacht about is two separate 48 volt banks. I know the numbers come out in favor of a larger single bank, but I believe the safety gained by the redundancy of two banks is worth the slightly reduced range and extra systems cost.
