Extra installation care needs to be taken with the stray current in an aluminum boat while running a Hybrid electric motor. Years ago, the German manufacturer of the Distancia 60 built-in fiberglass had a generator running an electric motor advertised. When I sailed her in La Palma, I found they removed them to Volvo diesel motors because of damage created by Stray currents from the e-engine they had installed. The stray current damage was done to the prop and prop shaft. Since
I am an owner of a 15-meter sailboat, and I'm very sensitive to even leaving my boat at a marina pen. I had left my boat for 4 months in a marina. What happened was the anodes dissolved in a few months at a guess, and then after four months, a few pinholes leaked water into the hull because of corrosion damage because of stray currents leaking in the water from other boats connected to shore power. I will only stay at a marina for a few days at most, I have it moored on its own mooring 99 percent of the time when not sailing. Best SV Skoiern IV

Ahoy guys, so excited for you! So I did some calculations a while ago based on our electric cooking. We got rid of propane 5 years ago and went with induction stove and electric convection oven, along with a electric kettle for tea and coffee. Averaged over a 30 day period we use about 60AH @ 24V, so approx 1.5 KWH for cooking per day. For the electric kettle , assuming it's 2KW (most are close to this) to heat up 500ML of water takes about 2 mins. 2/60 = .033H X 2KW = .07 KWH each time you use the kettle to boil 500ML so it's pretty minor. We have a 9.6KWH Lithium bank and found this to be plenty for our needs. Hope that helps! Brian

hi have you seen the bybrid motor they put in tally ho on sampson boat co channel?

Funny, over the past few years the conversations were all about "I don't think it'll work/ can't trust it/ no systems available", now we're spoiled for choice and we talk about scaling systems over time to keep up with the rapidly evolving innovations.

Regen and electric drive on a sail boat make perfect sense! Electric drive is so much more reliable than diesel only. The availability of much more electric power thru regen gives heaps of extra comfort. I did convert to lithium and induction cooking 2 years ago. I modified two 750 watt induction chafing dish heaters to go beyond 100 C to 180 C for baking, by adding a resistor to the temperature sensor circuit. Normal induction is often sold on being much faster than propane. In my setup it is a bit slower, like Alcohol cooking. Advantages are no hassle with bottles, but most of all only the pan heats up, the galley doesn't. The power need in my case is very little. 50 watts for a single cup of coffee. 250 Watts for doing dishes, 250 Watts for a simple meal like mac and cheese or 600 Watts for meat, potatoes and veggies (yes, I am Dutch:-). My 2 kw battery lasts me just over 2 days including a small fridge.

Hello Paul, hello Sheryl

I work in the RV industry and a few weeks ago, I had the opportunity to talk to a sales guy from a Munich based company, which builds and sells compact fuel cell generators.
I asked him who is buying these generators, because big solar systems are almost standard on the bigger RV‘s. And you don’t need solar and a fuel cell in parallel. His answer was astonishing: it seems to be very popular with the sailboat customers! Because solar is always compromised by weather and the shadow of the tall mast and rigging. And of course the independency from good weather, which you need to create power from solar. I think he has a point.
Maybe you should also at least have a look at those fuel cells :-)

Many greetings from Germany

So much great info in this episode. A conversion to electric is an absolute must on my list. Though, knowing we will spend the bulk of our time sailing the BC coast, a serial hybrid probably makes the most sense. Just need battery costs to drop a little more!

Not sure if you follow the Tally Ho rebuild but there was a session on power systems that, if you haven't seen it, I thought you might find interesting/informative. This is a link to the session: https://www.youtube.com/watch?v=xohxmwPfctg

I think hybrid is best suited for a catamaran, given the ability to carry so much solar. There is a constant demand for electricity on board. Being able to use electric to get away, or into, a Marina or anchorage would be nice, but it is done at the expense of “stealing” battery capacity from the house needs. Even if price were no object, a monohull has more space constraints for battery storage. (if you keep them low in the boat) With lithium’s increased charge times, adding a high output generator to facilitate charging while motoring into and out of marinas etc is probably a better way to go. Maybe one day a boat designer will design a boat the way Tesla designs their cars, incorporating the batteries as part of the structure, integral to the car/boat itself. A little outside the box thinking could go a long way – could not some part of the keel be used for storage? Just thinking out loud, best of luck with the boat!

On our Boréal 47.2 Fabule (Canadian registered) I cook a meal for 4 with 10% of our 10 kWh Li-ion bank, so about 1kWh. For more elaborate cooking I would count 1.5-2 kWh per meal.
On passage the most demanding equipment is the auto pilot, with the fridge and the freezers. Drains about 4-5 kWh per day including pilot, electronics and life support ( freezers, fridge, microwave oven and water boiling, and water maker).
No AC though which drains a lot of power.
Generation:
2x 350W wind generators,
900 W solar arrays,
600 W Watt&Sea hydro generator.
Diesel 4kW generator for hopeless days without wind or sun (and to drive the dive compressor).
Hot water for shower is on hydronic diesel Webasto or with diesel generator.
I would increase solar if I could (lack of place on monohull unfortunately) but the rest is sufficient even on cloudy passage so that the genset is almost not used, but this includes often bit of motoring which tops up batteries, say 10% of passage time in average.
Hope to cross path on the sea sometime.
Salutations de Lagos.
