How to Choose the Right Bow Thruster

Great Points to Keep In Mind When Looking For You New Bow Thruster

Raritan Engineering Company your Raritan marine products experts would like to share with you these topics we thought would be of interest to you this month regarding how to choose the best bow thruster for your needs.

Your Raritan marine products suppliers talk about how bow thrusters come in many styles and sizes. Before choosing a thruster for your boat, many factors should be considered with guidance from knowledgeable dealers and installers.

Consider these factors when choosing the best bow thruster:

  • Strength of winds and currents – The more the wind and water move in your environment, the more power you’ll need from your thruster.
  • The boat’s profile – The higher and longer your boat’s superstructure, the more pressure a thruster will need to push against a cross wind.
  • Bow shape, interior space – The deeper your bow is in the water, and the more interior space is available forward, the more easily a bow thruster can be fitted.

The example shows the different wind speeds that two different thruster installations can encounter and the increased leverage gained when the thruster is positioned further forward.

Significantly lower installed cost, more responsive performance, no mounting holes below the waterline, virtually silent operation.

Tunnel-style thrusters

Although occasionally found on smaller boats (less than 30′ in length), through-the-hull or tunnel-style thrusters are usually found on larger boats. 

First, two large holes must be cut or drilled on either side of the hull below the water line for the tunnel/tube to be passed through the boat. Correct tunnel placement is critical and requires a skilled installer experienced in structural fiberglass repairs, because the area around the tunnel on the hull’s exterior will require fiberglass work, paint and gelcoat. It’s not uncommon for a through-the-hull thruster to experience leakage over time that can void the boat owners hull warranty. 

Sideshift thrusters

Sideshift invented the original externally mounted bow thruster. Choosing a Sideshift bow or stern thruster offers numerous advantages over traditional tunnel-style thrusters. Significantly lower installed costs.

So don’t forget these great points when considering your next bow thruster purchase. 1) Strength of winds and currents – The more the wind and water move in your environment, the more power you’ll need from your thruster;  2) bow shape, interior space – The deeper your bow is in the water, and the more interior space is available forward, the more easily a bow thruster can be fitted;  and 3) the boat’s profile – The higher and longer your boat’s superstructure, the more pressure a thruster will need to push against a cross wind.

The world’s largest ever cruise ship, Symphony of the Seas, is nearly ready for its official maiden voyage on April 7, with Royal Caribbean putting the finishing touches on their new ocean liner before it departs from Barcelona.  The new ship, which will set sail in early April, surpasses her sister Harmony of the Seas in size. Symphony of the Seas was built in the Chantiers de l’Atlantique shipyard in France and is the fourth ship in the Oasis class. 

The ship cost Royal Caribbean more than AUD $1.7 billion to construct. The 230,000 tonne ship features a large waterslide on the pool deck. With the ship standing more than 18 decks high, the view from the waterslide is bound to be impressive. The outdoor pool area also features a children’s water park.

Similar to many of Royal Caribbean’s other ships, passengers will be able to surf on the ‘FlowRider’. After all the excitement on the pool deck, you wouldn’t be blamed for taking a nap on one of these comfy deck chairs. There will more than 2100 crew members on each voyage to help keep things running smoothly. There will be at least 20 different dining options for passengers to try out. And while it’s the world’s largest ship for now, Royal Caribbean already has plans to build bigger and better by 2021.

New Ways to Use Your Outboard Engine to Catch More Fish

Your Outboard Engine Is Your New Fishing Partner

Raritan Engineering Company your Raritan marine products experts would like to share with you these topics we thought would be of interest to you this month regarding how to use your outboard engine to help you fish. 

Your Raritan marine products professionals talk about how surrealistic car commercials: Driver dials a knob on his dash and his pickup truck precisely and skillfully backs his trailered boat. Guy pushes a button and his luxury vehicle parallel-parks itself — hands-free.

That same kind of abracadabra control has come to boats, and it’s beginning to have a significant effect on fishing. 

Those of us “of a certain age” ­experience a creepy Orwellian sensation when we see this electronic voodoo. Others just marvel, mouth agape, at the technology.

Outboard Control Features

“Originally, we were only factory installed. You would go to a [boat] dealer and buy a boat either with or without Helm Master,” says Ry Landry, Yamaha marine product and information specialist.

When SeaStar adds the SeaWays Autopilot feature (expected early this year), it will be a free software update install-able by dealers.

Yamaha Highlights

“I hate change. But this has made me such a better fisherman, it’s not funny,” quips Capt. George Mitchell, a longtime tournament angler out of Florida who has been using Yamaha’s Set Point features with Helm Master since those updates were announced last February.

Yamaha’s Set Point system includes three functions:

  • Stay Point: Holds the boat’s ­position and heading. Best used when you must hover above a specific location without swinging or drifting. 

  • Drift Point: Holds the boat’s heading but not position. The bow maintains its orientation while the boat drifts with the current or wind.

  • Fish Point Bow: Holds the boat’s position with the bow pointed into the wind/current, using the water- or airflow to maintain heading.

But Mitchell is quick to point out, as were all the other captains and manufacturer reps we talked with, that having these functions is not an excuse to leave the helm.

Fishing Can Be Much Easier If You Use Your Outboard Engine

The noise and commotion that Stay Point can create can be advantageous in certain situations, such as near Gulf of Mexico oil rigs. Cobia respond curiously to new sounds. Turbulence can attract other fish as well.

SeaStar Updates

“When we were doing our ­investigative work to develop the modes for SeaStation, we spent time with charter captains to see how they would most benefit,” says Shane DeWitt, electronics product manager for SeaStar. 

SeaStar’s Position Hold uses the boat’s most natural heading and modulates the throttle to the engines, moving them with minimal shifting to get the desired performance.

Using these systems, anglers no longer have to rely on an anchor that allows the boat to swing side to side, Mitchell says. “With Fish Point Stern or Fish Point Bow, all you have to do is jog the joystick to adjust the boat. You’re not having to pull the anchor to re-position.”

Engine Setups

SeaStar’s SeaStation system integrates (at no charge) with the company’s Optimus 360 joystick steering package, which is compatible with twin-, triple- and quad-outboard applications for Suzuki, Evinrude and Yamaha products as well as twin mechanical Hondas.

With quadruple Mercury outboard setups, the two port engines might be tie-barred together, with regular and counter-rotating props. Ditto the two starboard engines. “It’s like a big dual [engine].”

These station-keeping and joystick systems all function similarly, employing a GPS sensor and other instruments mounted on the boat’s hardtop, several computers and devices such as inertial measurement units and digital compasses at the helm. 

Future Outboard Options

Outboard companies won’t say what features they might be working on next for station-keeping systems. SeaStar will soon roll out its SeaWays autopilot function, allowing captains to transit to a waypoint or follow a track using the Optimus 360 system.

“We’re always working on new things.” That’s all Mercury’s Balogh will say. “There’s a lot of interest in the joystick in general. We’re happy with the position we’re in right now.”

So don’t forget to use these three functions of your engine to help you fish better. 1) Stay Point: Holds the boat’s ­position and heading. Best used when you must hover above a specific location without swinging or drifting;  2) drift point: Holds the boat’s heading but not position. The bow maintains its orientation while the boat drifts with the current or wind;  and 3) fish point bow: Holds the boat’s position with the bow pointed into the wind/current, using the water- or airflow to maintain heading.
