Joysticks, Part 2: Aftermarket Options

In Part 2 of our look at joysticks for improving the slow-speed maneuverability of boats, we look at aftermarket offerings that can be used for retrofit projects. Many of these systems can be added to an existing boat-and-engine package to improve its handling and give the captain more confidence around the docks and in tight quarters. Let’s take a look at the offerings.

SeaStar Optimus 360

SeaStar Solutions has created a retrofittable Optimus 360 Joystick Control System that can be compatible with twin, triple, and quad outboards. Optimus 360 lets a captain move the boat forward, backward and sideways by pushing the joystick to the left or right, and even rotate with a simple twist of the joystick.

Optimus 360 uses intelligent programming to minimize the amount of shifting required to complete a maneuver. With progressive throttling, the joystick becomes a natural extension of your hand. A light push on the joystick provides minimal thrust while more thrust can be applied by pushing harder on the joystick. Boost mode increases the rpm to generate more thrust when needed.

The three-axis joystick is compatible with third party autopilot systems, has dual redundancy components and optional multi-joystick capability. The 360 package adds electronic shift and throttle, plus the joystick control to complete the system for mechanically controlled twin outboards. Basically, it replaces the conventional outboard controls and cables with fly-by-wire electronics. The i6800 control head allows full engine synchronization with one hand. Owners can set the level of throttle resistance and detent to match personal preferences. The CANtrak display, which shows the system status, can be customized as well.

SeaStar Solutions recently released SeaStation for those wanting to hold position without using an anchor. Applying the same smart algorithms to SeaStation as with Optimus 360 joystick control, SeaStar reduces unnecessary shifting and jockeying of the engines while providing position and heading functions for many engine platforms.

Twin Disc EJS

Twin Disc’s Express Joystick System (EJS) instantly actuates engines, transmissions and thrusters in proportion to the pressure exerted. Point the bow in any direction without moving from a fixed position. EJS adds thruster control to the slow-speed capabilities and directional maneuverability of the QuickShift/EC300 system.

When you reach open water, push a button to transfer control from the EJS to the EC300 levers for cruising. The joystick provides intuitive touch and quick response to direct your boat where you want it to go. It is designed for shaft drive diesel power packages to give owners virtually the same response as a pod drive system.

At the core of the Twin Disc Express Joystick System is the Twin Disc QuickShift transmission with EC300 electronic controls. The QuickShift transmission possesses proprietary technology that allows gradual loading of the clutch to provide various and infinite degrees of engagement.

This permits smooth shifting from neutral to forward or reverse, or even from full forward to full reverse. The QuickShift transmission’s ability to shift quickly, smoothly and reliably makes possible joystick control for conventional driveline systems.

Add the Twin Disc EC300 controls featuring Express mode for slow-speed control using familiar lever heads. In Express mode, each lever lets a captain instantaneously shift from forward to reverse and control prop speed down to 50 rpm while the engine remains at normal idle speed.

Twin Disc also has what it calls the EPS system that is an option exclusively for shaft drive boat owners who have the company’s Express Joystick System (EJS) in place. It can be supplied with a new build or can be retrofitted. A dedicated GPS determines the boat’s location and heading, then instantly directs the Twin Disc QuickShift transmissions and proportional hydraulic thrusters to achieve those coordinates. Working in conjunction with the EJS, it lets a captain park a boat wherever he/she wants and the system will maintain station.

ZF JMS

ZF uses its control system SmartCommand as a foundation. Subject to the vessel’s design and operating requirements (quantity of thrusters, working conditions, tide and wind) it can add the JMS (Joystick Maneuvering System) and then upgrade more with functions like i-Anchor and i-Drift.

Further enhancement is offered with ZF SteerCommand, which is linked to the SmartCommand control system for improved steering with fly-by-wire technology.

ZF’s Easidock ensures positive clutch response for smooth, precise maneuverability in confined areas. Easidock modulates clutch engagement and controls engine speed to achieve optimum propeller speed for safer docking. SmartCommand’s CANbus communication synchronizes engines in all modes without the need for dedicated buttons or switches.

When the vessel operator manipulates the joystick, the JMS system incorporates propeller control and varying amounts of thrust from the bow thruster. Proportional control of the thruster means smooth engagement and only as much thrust as needed to move the vessel in the desired direction. Proportional thrust combined with an electronic compass tied to the main JMS control unit means there is no vessel yaw during sideways movement.

ZF Marine’s patented iAnchor station-keeping functionality is also available. With the press of a button, iAnchor will compensate for wind and current, holding the vessel’s position to as little as a 1m (3’4”) radius depending on external factors at the time of operation.

i-Drift is the latest development to the control system, this allows the ability to control drift speed and direction when the vessel is in windy conditions, or active current. It’s the perfect solution to keen anglers when kite fishing, bottom fishing or game-fishing as some examples.

Sideshift

Sideshift is a revolutionary bow and stern thruster technology that offers an easy-to-install thruster solution for all types of boats.

The big difference between the Sideshift thrusters and conventional thrusters is they are externally mounted. The propellers are in direct contact with the water, providing an instant response when seconds count. Also, the external mounting system places the thruster further forward, or astern on the boat. This provides a pivot-point advantage and a more immediate response. An operator can also use a wireless remote key fob to synchronize bow and stern thrusters.
