Re: [Electric Boats] Re: Generator and battery charger

 

Some points .. both good and bad.

For 6 (5.6) kW, it is very heavy at 145 kg.
This is very good -- industrial long-term reliable equipment is like that.

Heavy/power output, low-load/system/hp, thermally stable with good dissipation.

Something like that, will last industrial hours with suitable minimal industrial maintenance.
10.000 - 30.000 hours.
I used to do such maintenance, with military jet aircraft (Mig 21bis) and power plants aka gpu.

Yet...
Recreational boats = yachts are used == 7 days / year.
If you do not use the engine/genset/gear, it will rust and die, over time.
Unless exceptional engineering resources are used to protect and save the motive components.

Boats die over time, not because they are used, but because they are not used, mostly.

My point & opinion.
IF you are going to use the boat/genset all the time at low-medium load.
Pick anything cheap, or maybe something like the fisher panda.
Any cheap import diesel genset will deliver power, for a long time, when used, often, at 50-60-80% of power.

The fischer panda is == similar to a northern lights.
Heavy, reliable, lasts nearly forever if you use it every now and then.

For fishery, world-cruise now, I would always prefer industrial stuff.
Fischer/panda, Northern lights, etc.

For "your-boat-now", 98% of people are better off with a 1000$ import diesel of 5-8 kW, you can throw away in 2-4 years.
Most boats are sold at less than 10  years ownership.

Recap:
Best for real-use industrial, Fischer-Panda or any of similar mass, always, when using 1000+ hours/year, or 40+ days/year, 24x7.
Less than 1%, probably less than 0.1%, of recreational boats are in this sector.
Even a powerboat crossing the atlantic, back-and-forth, every year, 3.500 m/leg, at 15 days each, is 30 days use.

This shows why recreational boats have very low use ...

Hi John,

I like (if I were in the position to afford) the Fischer Panda options as I'd prefer diesel to petrol:

Their Neo looks nice for a small system:
