| 摘要 |
The present invention relates to a navigational system and in particular, provides for the use of one or more vessels as shunters for maneuvering larger vessels in restricted waterways, each shunter comprising a body portion, a pair of clamping arms with each arm being pivotably connected at one end thereof to the body of the shunter with the opposed end of each arm being adapted to engage the hull of the vessel to be maneuvered to thereby exert a lateral force on the hull. Preferably, hydraulic jet thrusters are employed for powering the shunters and the shunter and the vessel to be maneuvered are inter-connected by mooring lines.
