Hi Pascal,
Motors are brushless ME0913 from Motenergy (5kw. I believe); packaged and programmed by Electric Yacht using Sevcon 4 controllers and belt reduction. E.Y. need to have Sevcon 'brain' returned to them to make any changes to the controller. (I'm not smart enough to program them myself). Motors get a little warm. I understand they are discontinued. New one is ME1306.
My 48v. battery banks are 700ah each. (Got a deal from Balqon)
Electric Yacht recommended 260ah. for 3-4 hours motoring (if I remember).
So far we have motored about 8 hours under batteries alone.
We have Honda 2000 generator on board; 110v. into the charger. We can motor as long as we have enough gas (petrol). Solar panels will be installed on the hard Bimini soon.
The Farrier hull shape is finer than yours - so doesn't take a lot to move the boat.
We had mast problems soon after launch (still waiting for replacement); so have not sailed enough to check out regen; but from all info. found on this forum - we should get some regen. over 6 knots. We only need 10 kts. of wind for that.
48v. battery chargers are Chinese, purchased from Elcon in Sacramento. Do NOT deal with them - they will not answer questions about the products they sell. Chargers are programmed to cut off charge at 56.8v. (conservative)! The chargers are available under different brand names from others.
We use Victron battery monitors.
Cheers
Graham
