for only 1 hour a day to provide sufficient water, refrigeration and electricity. In some cases
1/2 hour will suffice but in hot climates 1 - 1/2 or 2 hours may be required. Remember that
you will consume a lot of electricity on board and most of it will be 12 volts.!
"QUEMALT"!
"Quintal Electric Marine" have developed an alternator which is totally automatic and
coupled to the propeller shaft. If your engine is equipped with a "Hurth" gear box, you can
let it freewheel and your batteries will be charged while you are sailing. The first tests of
this system were made by "Quintal Electric Marine" on a CORBIN 39. With a 3-blade, 18"
X 12" propeller, the alternator began charging at 3 knots and was delivering 20 amps at 7
knots. These results are extraordinary and, to our knowledge, there is no system on the
market that can compete with this performance.!
INSULATOR!
If you decide to install an additional alternator on the propeller shaft, it should be
connected by an insulator which is coupled to the engine alternator.!
GENERATOR!
If you prefer 110-volt, "Entech Inc." has one that will produce 3,500 watts and weighs only
160 lbs. Many of our customers have installed one. Please avoid the systems which will
start on demand; they will cause you nothing but problems.!
