How to wire for 220v?

Unbelievable! I was climbing a mountain today and my mind was wandering a bit and I thought... wouldn't it be nice to market a keg-erator for boats... no more bottles! Of course the first problem I came up with was with all the pounding and shaking... FOAM! I may have a workaround for it...

But your 30kW radar... are you sure it doesn't want 440 3 phase, or even something hotter? Sounds like time for a designated generator...
 
Guess it was a lousy attempt at humor; but an ice cold draft sure would be nice.
Actually, I was wondering what use a 30 kw radar has. I know large ships have huge arrays like this and larger, but what's the practical reason behind it? Certainly it's not collision avoidance, you don't need that much power. Tracking weather fronts/systems is done by more sophistcated electronics.
So what's it for?
 
Higher power rating means longer distance for starters, plus the ability to provide power to a larger array. The ad stated this set up powered a ten foot array (vs abt 4 for a 8 Kw). The larger array means more definition in the return image.

Since radar is line of sight technology, this would be largely a waste on any vessel like a Sea Ray because the height above water results in a horizon well below the effective range of the beam. On a larger vessel like a yacht with a 50 ft height above water mounting, it would be a different story.
