Join the Electric Revolution!
ST 37 single-motor drive |
STI's high-torque,
low-rpm motor drive provides clean, quiet electric power drive systems
for all kinds of boats.
It replaces diesel or gasoline engines
in
- sailboats
- displacement powerboats
- workboats
- water taxis
from 20 to 55+ feet in length |
System Overview
The basic STI system includes
drive unit (containing one or two motors) to turn the propeller
controller to operate each motor
bank of twelve batteries to supply 144 VDC to the
motors
power distribution busses
shore-power battery charger
Batteries are regenerated under sail by the
prop spinning in the wake. Hybrid-electric systems also include
a DC generator to recharge batteries for long-distance motoring
and heavy auxiliary systems use. An optional inverter supplies
120 VAC for onboard appliances.
Boat owners are responsible for
propeller
prop shaft
stuffing box
# 410 shaft coupling
ventilation system for battery storage area
ventilation system for motor compartment
main 12 volt power switch for house batteries
12 V house power system

System Options
Solomon Technologies offers two basic "power
charging" system options:
Basic Battery Bank Only.
Those whose sailing style includes day sailing, weekend, and
short holiday cruises may choose our basic battery bank only
configuration without a backup generator. (For more information,
see Fuel-free Motoring.)
Hybrid Electric. Sailors
who go on extended cruises and ocean crossings, have extensive
motoring requirements and/or a wealth of electric-powered
systems on board may choose a hybrid-electric system, with
a diesel generator backing up the battery bank. A hybrid system
will supply plenty of power for long-range motoring and amenities
desired for extended on-board living, including refrigeration,
air conditioning, electric stove, microwave and hair drier,
to provide all the comforts of home. (For more information,
see Better Fuel Economy/Extended Range
and Fuel Efficiency Comparison)
Racers may want to order a customized lightweight
configuration that provides generator backup with a smaller
battery bank strategically placed for optimum balance. (See
Condor 40 installation and
Prop Size Matters.)
Going "Green" and Going
Solar. There is no hard-and-fast rule for choosing
a battery bank only vs. hybrid electric system. If, like many
sailors, you enjoy traveling solely from the energy of wind,
water and sun, you may opt for our battery bank only system,
even for extended long-distance cruising. The longest-distance
STI customer we know of - a retired Los Angeles physician
- has been at sea for years with a battery-bank-only system
and no backup generator. He has successfully sailed the Pacific
to Tahiti. And for the "green" sailor who wants
additional power, boats with sufficient room for a 12 panel,
144 VDC solar array can gain supplemental electric power for
battery bank recharging from the sun. A young environmental
executive from the Washington DC area is outfitting his Hunter
38' with an arch platform-mounted solar array that will collect
energy and serve as a bimini for his aft-cockpit sloop.
