BT,
Not many replies; so I'll tell you about my ongoing project.
I'm buiding a Farrier F-41 cat. I decided some time ago to go
electric, and have picked up so much info. from the forum - especially
from Eric (many, many thanks Eric for your input - I'm sure others
really appreciate that)
I have 2 Sillette-Sonic saildrives, and should soon receive 2 180ibl
motors w/belt reduction from Scott at Electric Yacht, who has been
very helpful.
I'm going with 15" fixed props (for re-gen.) I've had to mount the
drives at an angle inboard of each hull, as I've only built 5" mini
keels, and I want to be able to beach the boat for bottom
cleaning/service etc. I didn't want to mount on centreline, because it
would have meant them being mounted just in front of rudders (hull
shape) So they are exposed to some extent to logs, etc. I live in
B.C., where the logging industry is a little lax about cleaning up
their 'escapees'.
I'm planning to use LiFePo4 batts., as they are really the only choice
(at the moment) for lightweight cats. Scott has recommended 230 Ahr.
banks for traction.
I hopefully will be sailing south to the warm areas of the Pacific
some time next year when I'm finished building; so I will also have a
small gas generator for emergency power for the motors. Down the line
I'll add a few solar panels to add to charging for house & traction
banks.
As you already have drive lines in the boat; you should be able to
adapt motors to your existing drives; but you may have to re-prop.
If I can help with any more info., let me know.
Graham
