Yachtwork kits - An out of the box solution
Yachtwork kits arrive standard with a double groove, 1/2" V belt
drive pulley, for ease of maintenance, compatibility, world wide simple
belt replacement, and reduced side load.
Yachtwork economical mounts accept the J180 standard alternator. The
J180 is the worlds most popular alternator mount and in use on every
type of heavy equipment, large engine, road truck, the large frame Balmar
alternators and the Electro Maax .
To you this means an inexpensive alternator is available ANYWHERE
in the world.
All our mounts are made from steel. Steel is used by EVERY major engine
manufacturer to build alternator mounts for two reasons-
* Steel has vibration resistance that provide years of trouble free
service.
* Steel matches the engine’s galvanic voltage potential, thus
preventing rust.
Ever notice how stainless steel makes steel rust?
That is because they are dissimilar metals and should not be mixed in
a marine environment and why Yachtwork uses steel mounts.
Yachtwork kits have been proven in the field for over 20 years.
Yachtwork produces brackets for most boat types including-
Catamarans,
Beneteau,
engines under stairs, or
wherever you have extra space.
Yachtwork marine alternator kits fit the Beneteau series of yachts
and were built specifically fit the new Oceanis 43, 46 and 50.
Yachtwork produces alternator mounts that couple the new 4JH4 and 3/4JH5
Yanmar to the 130 amp, Delco large frame economy alternator, the high
quality low RPM Electro Maax large frame marine alternator or the Balmar
marine alternator.
Yachtwork designed the elegant mount for Yanmar New Zealand and it
fits the Beneteau 43 perfectly. It is now one of our best selling mounts
producing a combined steady 245 amps to charge marine marine batteries.
Yachtwork even just built one for the CEO of Team New Zealand.
Yachtwork customers rave about there high quality products. It simply
ends the issue of charging marine batteries.
"I would recommend the system to every Beneteau cruiser over
other charging systems. I love it...
We use all the power we want including a 600w inverter for laptops,
battery drill, camera etc and have never been below 700amps in marine
batteries.
No doubt your kit was one of our best investments and the price
was perfect at the time. Your kit and instructions were incredible.." Ross Blackman
CEO Team New Zealand and Beneteau 43 owner
With today's high electrical usage in yachts, the ability to fast charge
is now more important than ever. Many yachts have over a 600 amp hour
battery capacity with 1200 amp hour not being uncommon. To charge a
system that large the old single 80 amp marine alternator (that really
puts out 70 amps) can take hours to charge.
The Dual Alternator option is the simple solution for the long range
yacht. You receive two direct advantages with separate marine alternator
systems.
Charging time may be reduced by more than 80%.
Second, and maybe more important is the security in knowing if
an alternator fails while underway you are covered as the second alternator
continues to charge.
For example, I know of many boats that have overheated a single alternator
while underway only to have the marine batteries slowly go dead, with
the engine still running. The wind came up but the crew could not shut
down the engine as they would not be able to restart with dead marine
batteries. They were sailing at night making decisions weather to run
the radar or the running lights.
If they had had a dual alternator system they would have simply noticed
the problem, noted it in the log and dealt with it at their leisure.
Customer base for Yachtwork high amperage kits include:
Offshore cruising yachts
Charter yachts such as the Moorings fleet
Beneteau production yachts
Marine electricians wishing for an easy method of driving a large
frame alternator.
Yachts with moderate electrical loads that do not wish to dedicate
space, effort and spares to a genset.
Large amp hour battery banks
Yachts that wish to shut down the genset while using the main engine
Marine batteries such as AGM that can take high charge rates
Split voltage charge systems IE 12/24 volt electrical systems
Yachts with large inverter loads ie. washer/dryer
Yachts that wish for a back up charge system for safety
Yachts that wish to utilize short engine run times to quickly recharge
marine batteries such as cruising boats that only run the engine when
lifting anchor.
Yachts with large electrically driven motors such as electric bow
thrusters and electric anchor winches
