It seems he's pimping the bolt on tee bar thing. He is intentionally ignoring the fact that it will dive in and out of the water as the boat passes over waves. Those bayliners, and any small boat really, will slam down after every wave they hit.

He doesn't seem interested in a real thruster. Just the bolt on toy.

I agree with the other posters, a bow thruster is too much project for a an older Bayliner. Wouldn't you rather have 5k worth of tackle?
Where your slip is makes a difference. I try to get one without a boat on the other side and the prevailing breeze blows you into the slip. That way you get close, cut the power and drift in.

A 5 series Vetus thruster will do the job for you. The big issue will be the current that the thruster needs to perform properly. As I am not an electrician I can only tell you that the bigger the battery the better, A 4 or 8D should do the job with enought reserve. In order for this to work you will also need to look at you alternator and its ability to charge the battery. Contrary to the captains with 1000 ton credentials advice on this thread if you want a thurster go for it. There are many boats in the 25 to 30 foot range that have thursters.

Rather than spend $5k get a personalized boat handling course from a pro.

You'll need at least 3 Gigantic batteries in bank for those babies and other electronics on the boat.

Whatever...........

Good luck with the project. I predict it will be a disaster due to the type and size of your boat. A lot of hull reinforcement will be required to do the job right. Battery storage should not be a problem but you'll need some space to route the large cables from the batteries to the thruster motor. Done right, this will be a very expensive project.
butch it must be hard to be as bright as you are thanks for all your information ,

Learn what a spring line is, and how to use it. All you ever need.

Unfortunately, your statement that a spring line is not valuable when docking highlights how little you are aware of about maneuvering your vessel. Sorry, but it is a fact that spring lines are very helpful in a variety of docking situations, especially when coming into port.

I pilot a 38' Jupiter with NO bow thruster, in a canal that is 49' wide including several very tight turns. I have to pivot it around using only the two closely spaced motors within that 49' area, and when the winds are up it can be very challenging due to the very small amount of space.

For what it is worth, I've only been piloting my boat for WEEKS, and have already found extremely high value in spring lines for docking needs. Granted, I grew up around boats so I do pick up quickly, but this is the very first outboard boat I have owned! If I can do it, so can you!

Use of a spring line allows you to jump the boat or stern away from the dock, or alternatively when coming in pull the bow or stern into the dock.

On a 26' boat, having a bow thruster is completely unnecessary. you can easily use the boat's power to maneuver, you just need to know how to do it and how to use springs to dock properly.

I know you're defensive since folks are taking shots at you, but really do spend the money learning how to pilot your vessel. It will be lots cheaper, and less hassle!

Default Sea Quest 38 narrow fairway

Thanks forebones for starting this conversation and taking all the advice.

I'm about to buy a Sea Quest 38, single screw 195hp and am nervous about docking. My slip is angled so as to be easy to get into bow first but Id rather back in.

Fairway is maybe 20' wide, I'm 6 slips in with a 45 degree turn to port to get into my slip. I'm in a double slip with my dock on starboard if I go in bow first.

Backing out my stern will go to port so it should be easy enough to back out by getting up enough boat speed and going into nuetral, wind permitting.

Backing in, not only do I have to get up enough speed to steer in reverse in nuetral, then I'll need to swing my stern to starboard.

To paraphrase, I don't want to approach a neighbor's boat faster than I'd like to hit it. I know only rookies buy stern thrusters but I'll lose a lot less pride installing thruster than repairing boats and docks. Spring lines do wonders but I want to be able to come and go single handed.

Any suggestions?

Sounds like you have a straight drive inboard, not an I/O like the OP. A bow thruster is really nice to have on one of those. You can get a lot done with a single and no thruster but it takes practice backing and filling, knowing how to use the prop wash and the rudder and bursts of power. Try that first before getting a thruster; you seem aware of the effect of your prop wash, use that with some practice, you are already on the right path.

I bought the Lewmar 185tt bow thruster for my boat/24' cruiser. Heard the same arguments from all my friends about docking lessons. I did the install myself about 4 years ago, and if I remember correct it took about 2 1/2 days for the install and cost about $1500.00. Best money I ever spent [except for the boat], took all the stress out of docking the boat. Anything that makes my life easier I'm down for...

Single screw inboard I would totally install a bow thruster. Well worth it in that scenario! Stern thruster not so much.

Think most will find the cost well exceeds $1500. If it was really that cheap for the gear and install, wow!

Those prices was about 4 years ago. Do a google search and you will find the price for my unit is about $1400.00 plus accessories figure about $2000.00 today. Shop it and you might find it a few hundred cheaper...

Ah, I'm not talking just the cost of the thruster. Install is where the cost is expensive on most boats. It is a solid $8-10k for one on mind, even thought the thruster is $1699.

Did my own install. Not to trustworthy with my stuff and other people touching it. My unit came with detailed instructions, been 4 + years and work flawlessly...

I put a Vetus bow thruster on mine, twin inboard, 25 ft, w/o counter rotating props, it was a lot more work doing the tunnel than I expected. Inside glassing and fairing it up took a lot more time than I thought it would.

I come in off of a tidal canal with a ripping current into a narrow calm canal with boats on both sides. It used to be white knuckle coming in the entrance if the tide was running out or coming in, now it's easy. It replaces the mate with a boat hook ready to fend off. They are also a really fun toy to play with when docking

Gerg, you the man. I didn't notice that until you mentioned it. I was about to reinforce the docking lessons. Agreed. Caught red handed.
