T&T: Fw: 110vac

[Larry N. Brown]

Capn Al-- The late Al Pilvinus- had an elegantly simple solution to this 
problem. The cruise generator. You can find good quality brushless generator 
heads all day long on Boats and Harbors at ridiculously low prices. Belt 
drive on to a main engine through a clutch and pulley it so it generates 120 
vac @ 60 htz at your optimum trawler cruising speed rpm. Wire ultrasensitive 
loads through a  PSW inverter. For KISS, remotely control the clutch so it 
doesn't spin when you have to play with the throttles. Or automate it the 
control.

Capn Al said it save his bacon on many a Bahamas charter.
