Hull weight is 800 lbs. I think all set up it’s around 1200. So pretty light for a small cruiser.

Re: Maximum input voltage for outboard?
A change in plans due to the weather forecast: My launch has moved to 1 PM on Sunday the 23rd. Chance of rain, but not as much as Saturday. Fingers crossed. :)

Re: Maximum input voltage for outboard?
Hello again,
After resolving the wiring and voltage issue (went with changing to 24 volts just because it was something I could quickly and get the boat on the water.)
Speaking of which...? if anyone in the area would like to stop by at the official launching, I intend to put her in the water at the Magnuson Park launch ramp on Lake Washington at around 1 PM this coming Saturday (the 22nd). There's still some work to be done, but the "make it go" system is functional. :)

Re: Cutis 1238-5601 Motor controller failure.
Mine did something similar, check the motor encoder, thunderstruck has a page explaining how to change out and test.

Hello,

I was getting error message 37 “motor open”.
I spoke with Bill over at HPEVS, when I told him the leads from controller to motor tested good, he right away suspected the controller.
He was going to have me send it in to them to see if they could fix it, but when I told him I could hear something rattling around inside he said sounds like a fried MOSFET and suggested I send it to FSIP in Pa.
FSIP will ONLY do a full reconditioning for $1200.00, tempting as it will come back like new condition with a one year warranty.
But I was curious if anyone knows a place that might just fix what is broken and cost much less, or if any one has opened up the case of one of the Curtis controllers and had any luck replacing burned out mosfet’s.
I think FSIP’s price to rebuild will be the same even if I was to mess up up even further!
Thank you for any help you can offer!

Re: Cutis 1238-5601 Motor controller failure.
I've killed two Alltrax controllers. While I can't speak for the Curtis, the Alltrax were effectively unrepairable as the entire circuit board is encased in resin. However, I imagine any controller that could be potentially exposed to water is potted in resin to repel water. To do a board repair on such devices means you have to dissolve the resin first and then clean the residue off the board so you can solder. None of this is impossible, but it's labour-intensive. It's often cheaper to just get a new unit.

Re: Converting an Allmand Sail 31 to electric
Hi Dan! Thank you for the article, it looks very detailed! I have a lot of questions that I want to ask you but as I read I find that everything is very well explained on your website, thank you for sharing it!
After I finish reading it in its entirety, I will ask you for some doubts I have.
Keep in mind that I have my boat in the water and I don't see the possibility of taking it out soon.

Re: Converting an Allmand Sail 31 to electric
Hi Agustin,
All in one units like the one you chose is find for house, maybe even an RV. For a variety of reasons some obvious some not, an actual marine rated rated inverter will serve you better. Probably more expensive but may be worth it. Look into Victron.?
Look at the specs, on your inverter. The minimum solar operating? voltage is 120. You will have a very hard time achieving that on a your boat.?
I have not yet seen a use case where CIGS make sense. Better shading performance maybe but it will almost certainly not make up for its much lower overall efficiency.?

Most say 100w or 200w and then you have to check the sizes within each publication and that makes it quite difficult.

Re: Converting an Allmand Sail 31 to electric
No se perfectamente como funciona el inversor solar, pero el mismo estára cargando un banco de baterías de 48v y 320ah. No se por que se llama inversor solar, o lo venden con ese nombre. Pero en realidad es un Cargador MPPT de 48v + Inverter 48v dc to 120v ac. Y tiene la capacidad de seleccionar cuál es la fuente preferida de energía, puede ser la red externa, puede ser la energía de paneles, o puede ser las baterías.
No se si alguien mas probo utilizar este tipo de equipos en barcos, por lo general veo que tienen todo por separado.
Yo elegí este, por qué me da la opción de conectar un generador o una fuente externa de energía sin tener que modificar ningun switch. El administrará la energía de forma transparente, o eso al menos espero.
Todo se encuentra en etapa de desarrollo y aún no tengo todas las partes para probarlo…
También me gustaría saber de paneles solares, por que por el momento vi como una buena opción los paneles CIGS que tienen menor pérdida por sombra, pero son más caros.
Y por otro lado, no logro encontrar paneles que los publiquen por su tama?o, algo que es por demás importante en un velero.
La mayoría dicen 100w o 200w y luego hay q verificar los tama?os dentro de cada publicación y eso lo hace bastante difícil.
Estaba pensando en dibujar la superficie del velero y empezar a calcular cuál será la mejor distribución.
La cantidad de paneles que coloque será la capacidad máxima que pueda. M Agustín Filsinger USA +1 929 255 5418 ARG +54 9299 521 0128

When I removed the old motor I took out everything it had, including the cooler and the pump, the truth is that everything was in poor condition.
Now that I am going to buy the electric motor, if I choose the solution with liquid cooling I would have to buy the entire cooling system, and if I choose the air-cooled version it is not much of a problem because I have 2 new blowers that I was thinking of installing for an air conditioning but that idea was cancelled.

Re: Converting an Allmand Sail 31 to electric
Thank you! That's the kind of help I need. Well, I'm telling you that I had also thought about it, but I wanted to install several of these "Solar inverters" connected in parallel to distribute the loads. But the problem is that for 110v only 3000w come and not 5000w, which seemed to me very little for them to be two.
I like these equipment because they receive off-shore energy or generator, and also that of solar panels, they also have the batteries connected, and they manage alone from where to get the power, if it is enough they use the one from the panel, if more they take out of the battery, and if the generator or the marine plug is connected, they take the energy from there.
I also found on AliExpress that I can buy separately the plate that gives the team the support of another in parallel.
The good thing about that is that you have double everything, and I could use both at the same time or one of each.
That was my idea, to have redundancy.
But it would not be bad at all to have a small inverter in case of failures, also a mppt charger.
