Cruising with Talamod

Wooden Classic with JT-30 Bow Jet Thruster

Docking a boat can be a real challenge: You've got the wind, the tide, and navigating through smaller marinas can really stress you out when you find yourself in a tight spot. That's where bow thrusters, and nowadays, stern thrusters too, come in handy. They not only add to safety but also help prevent any damage to your boat's delicate paintwork.


But, you know, despite the obvious benefits, some folks we meet at boat shows seem to think thrusters are unnecessary. They'll say things like, "Just learn how to sail properly!" But as manufacturers, we know better. We've been out there on the water ourselves and have seen firsthand just how tricky it can get.


"I've had my fair share of experiences navigating boats, especially in my part-time gig as a captain for a Dutch boat tour company. We operate four classic boats in our bustling hometown and let me tell you, there are plenty of situations where you wish you had a bow or stern thruster. So, in this article, I want to share some real-life stories that highlight the importance of thrusters in navigating the waters effectively."


Being out on the water offers both relaxation and a dose of stress. Amidst managing a company and crafting our Jet Thruster systems, the water serves as a sanctuary for clearing the mind. There's something truly blissful about hopping aboard a boat and gliding through the waters surrounding the picturesque city of Dordrecht. Nestled at the confluence of several major rivers, this city boasts a bustling waterfront steeped in history.

Si-Barone - Boat Tour Company

From bustling barges to commercial vessels, and an array of support crafts including water taxis, law enforcement, and rescue teams, the waters here are alive with activity, especially during the summer months when pleasure boats from around the globe flock to Dordrecht. Amidst this lively scene, you'll find the boats of Si-Barone Boat Tour Company, offering tourists from far and wide the chance to experience the city's charm from the water.


Operating four boats during the tourist season means constant movement through the channels and ancient marinas. With a climate that fluctuates throughout the year and a year-round tour schedule, our part-time captains have plenty on their plates. The ever-changing conditions, from sudden winds and shifting tides to bouts of limited visibility, keep us on our toes. Safety and maneuverability are paramount, especially when waiting for a closed bridge or navigating tight spaces.


To minimize the risk of accidents and ensure smooth operations, Si-Barone sought the expertise of Holland Marine Parts and opted to equip our boats with Jet Thruster systems. These systems provide the precise control needed for safe navigation in challenging conditions. Guest satisfaction hinges on a secure and comfortable tour experience, and seamless boarding and disembarking are essential. Jet Thruster systems lend crucial assistance during docking maneuvers, particularly crucial for our classic wooden boats, which lack the option for conventional tunnel thrusters.


Jet Thrusters, powered by robust battery-operated water pumps and small through-hulls, are ideally suited for wooden vessels. Their installation requires no extensive modifications or expensive epoxy work, making them a practical choice for our fleet. Take, for instance, Talamod, a classic Iverson from the 1950s, outfitted with a JT30 Jet Thruster boasting 30KGF of thrust at the bow. At 8 meters in length and powered by an inboard diesel engine, reversing such a vessel can be tricky due to its single shaft and large propeller. The strong prop-walk makes maneuvering near docks a challenge, but with the JT30 Jet Thruster in place, a world of opportunities opens up. As you approach the dock slowly, you can execute the following maneuver seamlessly:

Prop Walk

We're well aware that a right-turning propeller creates a prop walk, nudging the stern towards the port side when the boat nearly comes to a halt. We leverage this to our advantage: as the boat begins to move sideways, edging towards the port side, we activate the Jet Thruster, prompting the vessel to glide smoothly sideways. With carefully positioned fenders to cushion the boat's approach, it docks gently against the pier.


One of the most delightful aspects of the Jet Thruster is its whisper-quiet operation. This means there's no noisy thruster sounds disrupting the maneuver, ensuring a serene experience for our guests and peace for those residing along the waterfront in this area.


Given Talamod's venerable age of nearly 75 years, it's no surprise that modern technologies like the Jet Thruster were not available in its heyday. However, retrofitting the vessel with this advanced system posed no challenge. The Jet Thruster, designed to work with relatively standard through-hulls, can be installed by any reputable yard, boat technician, or skilled boat owner.


One of the standout features of the Jet Thruster system is its flexibility in pump placement. Unlike traditional propeller thrusters, which require the pump to be positioned close to the nozzles expelling water for thrust, the Jet Thruster's pump can be located anywhere within the boat, as long as it's below the waterline (given it's not a self-priming pump). This opens up a world of technical possibilities and opportunities previously unattainable. With this setup, any boat facing space constraints in the bow or stern now has the option to position the power source—the water pump—remotely within the vessel.


This innovative approach not only addresses practical challenges but also enhances the overall maneuverability and functionality of vessels, breathing new life into even the oldest of boats like Talamod.



Experiences

Let's take a deeper dive into how the Jet Thruster system functions. While we touched on one aspect earlier involving simultaneous operation with the main engine, there's a lot more to it. When we're cruising the intricate canals, we often find ourselves moving at a crawl. One big reason folks book our boat tours is to soak up the rich history of Dordrecht, the oldest city in Holland, which you can really appreciate from the water. Our captains don't just steer the boat; they double as knowledgeable city guides, filling guests in on the fascinating historical sites along the way.


We often slow down our pace to give people plenty of time to admire the architecture and to navigate around other waterway traffic. Now, historic boats like Talamod have tons of charm, but they're not the easiest to handle at slow speeds. With their relatively small rudders and no propwash, they're pretty vulnerable to wind and tide. That's where the Jet Thruster comes in clutch.


At the helm, there's a control panel with a joystick that lets the captain easily guide the boat where it needs to go. When you push the joystick, the directional valve kicks into gear, directing the flow of water. The pump springs to life, shooting the water through the Jet Thruster nozzles positioned just below the waterline. These nozzles shoot the water out horizontally, giving precise control over the boat's movement, even when we're creeping along.


So, in a nutshell, the Jet Thruster isn't just for docking—"it's also about making sure our guests have a smooth ride and can fully enjoy exploring all the amazing sights along Dordrecht's historic waterways."

Jet Thruster offers great and flexible Thruster solutions for Jeanneau Yachts. But there is more! Why does a Charter Companies like Boomerang Charter in Sardinia, Italy choose for Jet Thruster? The answer is all about performance and reliability. With almost every weekend a crew-change, there is not much room for maintenance during the busy season. It's super easy to catch a mooring line with a conventional bow thruster. Let's not even mention a Retractable Thruster. These thrusters are very vulnerable, and any damage results into unwanted time consuming repairs during those few hour a Charter Operator has time to change the crew. Jet Thruster however has NO moving parts in the water. The water will pass a small filter. No lines can be sucked into the pump unit. At the nozzle section, only 2" holes are present. From these nozzles, the water is pushed out by the pump. Nothing can get into the nozzle as there is no suction here. The pump inlet is located deep under the water line. The grate prevents debris, plastic and those floating mooring lines from coming into the system. All of this makes a Jet Thruster offers a high level of security and less in-season maintenance jobs for Charter crews.

The car industry already discovered composites many years ago. Jet Thruster systems are designed for the heavy use often seen in Charter Boat industry. Reliability is a very import topic. Due to the continuous use of the charter boats, and short service time, available between changing of the guest, there is a demand for technical equipment with a minimum service-level. With no moving parts in the water, no mooring-lines can be caught by the thruster. Mooring lines floating in the Charter base marina's are the no. 1 reason, traditional propellor bow thruster will fail. No with Jet Thruster. Lines are not able to enter the pump unit.
