For 40 years I only steered boats without bow thrusters, so know how to handle a boat. Then 9 years ago I bought a boat that happened to have one fitted. I mainly use it for reversing but occasionally use it to help turn the boat around if it is tight or windy. I think in the 10 years i have been on the cut there has been a handful of times that I think to myself that a Bow Thruster would have been useful there! Normally it has been getting in/out of tight marina spots. Link to comment Share on other sites More sharing options...
hypnoticmonkey Posted September 15, 2023 Report Share Posted September 15, 2023 Definitely an interesting read, this thread. I don't have a huge amount of experience in boating, but I've been on a handful of boating holidays and always had boats that didn't have bow thrusters. When you speak to others on the water I always picked up a snootiness about them, like it wasn't "real boating". I kind of get it that if I can start out with 0 experience and manage fine controlling and manoeuvring the boat without them, then they're not entirely necessary. Although, I've always taken the view that why make life harder for yourself if you don't have to? As I say, never used them myself, but I'd be interested to try. Hired a boat for a week in Ireland last year that was a lot bigger than I was expecting. The number of times that week I heard people saying "boat that big, I'm guessing you've got thrusters?" and it was always, "no..." followed by pained looks on the faces. Managed that fine without though! Link to comment Share on other sites More sharing options...

Managed that fine without though! Bow thrusters are never *essential* if you're reasonably good at boat handling, and certainly shouldn't be used all the time or as a routine substitute for the rudder -- and it's this type of boater that leads to the snootiness. But there are occasions when they can be useful, usually involving crosswinds or currents when the room to manoeuvre is restricted, especially when reversing. If people choose to not have them because they're not traditional, that's their decision, and that's fine. If people choose to have them to help in the above cases that's fine too, they're just another optional boating feature like a TV or washing machine. Steering down the canal with the thruster buzzing left and right all the time -- that's not fine... 😉 Edited September 15, 2023 by IanD 1 Link to comment Share on other sites More sharing options...

If you can't steer without using the thruster then when you need it, thats when it will suck the bag in. If you can steer then that is not essential but handy to have.

Tracy D'arth Posted September 15, 2023 Report Share Posted September 15, 2023 Funny how the gas always runs out when you are cooking. Oh, of course that is when I am using it, it never runs out when you are not using it of course. 1 Link to comment Share on other sites More sharing options...

magnetman Posted September 15, 2023 Report Share Posted September 15, 2023 (edited) The problem with bowthrusters is fairly basic. Some people (not all) will learn how to handle a boat assuming there is a bowthruster available if they have one. It appears to be an easier option but in reality it takes away a lot of the enjoyment and cerebral exercise involved in handling a boat. Anticipation, planning, helmsmanship etc. It also means that in the event of failure you are not competent to control the vessel. Bad news. On balance if I was specifying a new boat I would put a Very Good bowthruster in but the idea would be to never use it because it is basically not needed. Fire it up every now and then but definitely don't use it in the course of boating. On that one in a thousand very windy day where it could save your bacon you use it. I have yet to have one of those days on canal or Thames boating up and down long distances with no crew in various different heavy boats. A bowthruster would have helped but it was by no means needed. I did end up in the trees on a 72ft narrow boat once while turning and got pinned by wind in the barge enough to need to reverse out and turn around so sometimes it could be useful I suppose. There are always alternatives. Bigger boats can benefit from these and of course ferries etc have side thrusters and all sorts of clever gear but on a canal boat you basically don't need one. Its not a snooty thing its just a fact. There should be some sort of interlock on a bowthruster fitted to a new boat which won't allow the owner to use it until they have put a couple of hundred hours of cruising in on the main engine and learnt how to drive the boat with no bowthruster.

Push the stern out and reverse, then the bows will swing out or you are far enough away at the stern you can steer the bows out. Or use a spring to move the bows out if there isn't room to reverse far. 1 Link to comment Share on other sites More sharing options...

Well, I got very quickly wedged in the bank on my first try. Trust me to use a lock landing with broken planking/rubbing strakes.

Planned to moor in the lock entrance to the docks, to achieve this she has to maintain half ahead until her bow is already in the entrance when she goes astern to stop within half a ships length! Nicely done but nerve racking when they are aiming for your real estate! Later calls I was on the bridge and even more nerve racking!! Leaving that berth they just let go the lines and rang down half astern and go until they had sufficient sea room to come ahead with the helm over and head the right way! We used a tug to help with the manoeuvre. 1 Link to comment Share on other sites More sharing options...

They're not and also won't help if the boat is moving at any speed. They're only useful for slow, close quarters handling and reversing over distance.

magnetman Posted October 16, 2023 Report Share Posted October 16, 2023 I didn't mean while the boat was moving I was referring to getting away from the side when pinned. I'm sure it could assist in this scenario. If one is single handed, windy day, boat pinned to the side. Walk to front push it out walk to back and the front has gone back in. It is a typical scene. Without a secure bollard to reverse onto with a line to the stern dolly I do believe a bowthruster could be very useful in this situation. They definitely are not for steering when going forwards. That should be obvious. In two trips from Limehouse to Lechlade and back in my 57x12ft barge there was only one occasion where I did actually want a bowthruster. Pinned to the bank by the wind after mooring overnight. The solution in the end (it was Windy) was to reverse out, let the wind blow the boat round go the other way then turn around in a sheltered area then come back up. No one died but a bowthruster would have been handy. Link to comment Share on other sites More sharing options...
