The Waterjet Difference
 Waterjet
propulsion has many advantages over other forms of marine propulsion, such as
stern drives, outboard motors, shafted propellers and surface drives. These
advantages include...
Excellent Maneuverability
-
Precise steering control at all speeds
-
"Zero Speed" steering provides 360° thrusting ability for docking and holding
stationary.
-
Sideways movement possible with multiple jet installations.
-
High efficiency astern thrust with "power-braking" ability at speed
High efficiency
-
Propulsive coefficients as good or higher than the best propeller systems
achievable at medium to high planing speeds
-
Low drag and shallow draft
-
Absence of underwater appendages reduces hull resistance. Jet intake is flush
with hull bottom to afford minimum draft
Total safety
-
No exposed propeller for complete safety around people in the water
-
Low maintenance
-
No protruding propulsion gear eliminates impact damage or snags
-
Minimum downtime and simple maintenance routines
Smooth and quiet
-
No hull vibration, no torque effect and no high speed cavitation gives maximum
comfort levels on board
-
Low underwater acoustic signature
Maximum engine life
-
Jet unit impeller is finely matched to engine power
-
Power absorption is the same regardless of boat speed
-
No possibility of engine overload under any conditions
Simplicity
-
Single packaged module
-
No heavy and expensive gearbox required for many installations. Simple
driveline from engine to jet coupling
Easy installation
-
Complete factory tested package, ready to bolt in
-
No difficult engine alignment problems
Hamilton waterjets have several advantages over other waterjet makes. These
include...
Superior cavitation resistance
-
Pump design offers up to 25% more thrust than other waterjets between 0 and 20
knots. Maneuverability at low speeds & acceleration to high speeds are
superior.
Precise steering control
-
The unique JT steering nozzle minimizes thrust loss when steering. No central
dead band provides higher course-keeping efficiency and higher overall boat
speeds.
