May I suggest one of the ABYC courses.
Good one.

And you do that for a living?

Does not say much for the ABYC courses.

Got to be some blizzard, fog, pollution down there.

Re: ABYC Standards on new boats

Wow. just wow. How in the world does 120v vs 220v change the amount of greenhouse gas emitted? E=IR and P=IE. P is P. Burning coal, splitting atoms, spinning an alternator, or gathering sunlight - power is power.

Re: ABYC Standards on new boats

Wow.

Just try P = (I * I)* R and do not get too much a fix on the amount of greenhouse gas emitted but on the amount of heat produced.

That is incorrect in most boats. This is because in most boats under 50ft the AC wire gauge is determined by ampacity, not voltage drop. The relationship between ampacity and gauge is independent of voltage.

Another story is that for a given *power* requirement, 120V will require higher current than 240V.

Good move.
Less weight, you will be able to carry more ice cream.


The value for Electric power transmission and distribution losses (kWh) in Australia was 13,313,000,000 as of 2011 (5.27%). As the graph below shows, over the past 51 years this indicator reached a maximum value of 18,151,000,000 in 2001 (8.09%) and a minimum value of 2,646,000,000 in 1961.(11.48%)
