External thruster Not reccomended
Thanks for the advice. I single-hand a lot in the Chesapeake. I think an external unit might be my best bet. But would have to be even more careful about snagging a crab pot. Any horror stories of an external thruster snagging or being ripped off the boat?
Firstly, I know of 2 hunter 43 boats with bow thrusters. One of them was installed after delivery.
I would contact Hunter, and get specifics for any factory installed thruster options. That would be a good starting point.
I looked into the external thruster for my 49 as a stern thruster. I did a fair bit of research into the unit, and talked to the US representative.
I contacted their office, and asked if they had any existing installations on Hunter 49s. He told me there were several. I then asked him for one or two references. At that point he backtracked, and said they had installed on "many Hunters, but no 49's"
I made an appointment to meet with the head of sales at the Toronto boat show.
I went to his booth, and introduced myself. The sales guy then made me wait almost 20 minutes, while he talked with an obvious "tire kicker', paying no attention to me whatsoever.
When I finally got his attention, he told me which model I needed, and was 100% sure that it would work. I then asked him for the kW output of the thruster, so I could make some calculations confirming that it could handle the side load. He said he didn't know, and that nobody had ever asked him that question.
He then said that based on my displacement, I, in fact, needed two stern units; not one.
I then found out that the larger units were only available in 24 volt, requiring a complete set of additonal batteries, plus a 24 volt charger. This would be further complicated by finding a way to charge these batteries from shore as well as engine.
He then told me to buy it, and if it didn't work, I could send it back for a refund.. Pardon me, but i don't drill large holes into the bottom of my boat based on those types of assurances.
Just to find out how sincere his offer was, I asked if he would ship it to me, and I would install it. If it worked i would pay in full. If not, i would return it, and they would reimburse me for the cost of fixing my hull. he said they couldnt do that.
I then decided to ask Hunter their opiion on this unit. Their response was that they would categorically never fit one on a Hunter for either bow or stern application.
So, in summary I have little confidence in their salesmanship and customer support.
I believe that a bow thruster on the 43 is a good idea. It will assit you with docking in crosswinds, and probably bail you out of one or two scrapes.
I would also consider either a max prop or vari prop. The reason for this is that it eliminates prop walk in reverse.
Good luck
