Thrusters

We are contemplating installing bow & stern thrusters on our NT42. The yard is recommending Wesmar (they will install whatever we want) but I don't know one make from another. Another NT 42 has Sidepower with 10hp bow and 7hp stern; the owner is very happy with the product and the power.

So if we were to install ~ 10hp bow & stern thrusters, what is anyone's experience with different manufacturers?

We love our Side Power bow & stern thrusters believe they are about 12HP a piece, each has a set of 8D's tied into the house. Bank that give plenty of run time. They really help in close quarters.

Definitely a fan of the Coot's bow thruster. Question the cost/benefit/risk-of-damage of a stern thruster on the boat, however.

Thanks Oliver. 24V? That seems to be the preferred approach from what I've heard so far.

What manufacturer Mark?

When you are side tying to a dock in a parallel parking kind of way and the winds are blowing you away from the dock, a thruster at each end of the boat is very nice.

I'll have to look up the manual, which is on the boat. Please send me a PM tomorrow to remind me to look it up as I'll be on the boat Sunday. It's a 24-volt model. As far as the stern, I'm relying on the single-propulsion propeller and rudder.

The early 47's had 12v so they went with 12v thrusters since the rest of the boat is. They work great!

Wesmar makes good equipment.

I don't see the point in a stern thruster. Since you already have a very large one now.

These might be worth a look,

Wesmar is top notch stuff and they are based up where you boat. Shop around and get references, but that, or ABT, also a west coaster, is probably the direction I would go in. I'd also go just with the bow unit first then evaluate if the stern is really worth it to you.

If you were out here I would rec Vetus (which the Hatt has), simply because of the great customer service (which I have direct experience with) and reputation of their distributor and main installer Florida Bow Thruster.

I'd suggest talking to Nordic Tug. They offer Sidepower on the 42 new now. This is the standard bow thruster:

Bow Thruster - SIDE-POWERŪ SE100/185T-12V, 220lb thrust

I don't know the specifics on the stern they offer as an option.

They've had experience with a specific combination, locating them, and tying them in with the rest of the equipment. This is not meant as Side Power vs. Wesmar or anything else, just I always like the idea of following what the builder has had success with.

I am very happy so far with my 24 volt, 10 inch Vetus bow and stern thrusters.

Great Laker has Sidepower bow and stern thrusters. Both are very useful in many situations. Since the value of the stern thruster seems to be in question by some, let me give some examples where I have found it key.
  • Holding the stern close to a lock wall in winds and swirling waters when the main engine is off and the Admiral can't hold on to the line.
  • Moving the stern off a dock against the wind when there are other boats ahead and astern, and it is necessary to back away.
  • Steering the stern when backing into a slip.
  • Steering the stern when backing out of a narrow fairway into the wind.
  • Quickly spinning the boat 90 deg when in a narrow fairway with winds and needing to enter a slip.
  • Moving the stern over to get a line around a pile while in a slip.

I have said in previous threads that if I could only have either a bow or stern thruster, I would seriously consider just the stern thruster.

Really? You mean as opposed to the two giant ones you cut for a standard thruster plus the one cut in the tube to install the thruster unit itself?

Thanks Larry. You have nicely articulated the reasons that we are looking at installing both thrusters. At our dock, as mentioned, we often have the wind blowing us off the dock which is okay when leaving (although I do have to execute a quick pirouette once in the narrow fairway or the wind will put us into some very expensive yachts) but we also have hard winds onto the dock which can make leaving a challenge. We're pretty tight between boats fore and aft.

If a strong northwesterly is blowing off the dock there is no chance of a successful mating with the dock.

Using the stern walk is very helpful, but when you have very limited fore and aft room the stern walk can only do so much.

We have a very anemic 12V bow thruster (factory installed) that is virtually useless.

The comments are confirming my general impression that Wesmar and Sidepower are good units - thanks everyone.

Cool product.That would work on my shallow draft, but I plan to beach, and also dry out at low tide.I'd end up ripping my bow open below the water line.

With my single screw Carolina boat, I find the bow thruster very handy. I find no need for a stern thruster, anything back there can be handled by rudder/prop and alternating fwd/rev.

All these units (except hydraulic) have run time limits , find out what they are and be sure you can live with the restrictions.

If the purpose of a stern thruster is to get you off a dock with little space fore and aft, make sure you get a BIG one. I have seen a few collisions where the thruster did not get the boat clear fast enough against wind/current. God originally invented spring lines for this purpose.
