Great info. That midships transducer location did not work out so well.
I have to go back and try to get the transom transducer into better water flow.

Re: Transducer inside hull
Thanks for the info. I don't plan on worrying about the angle of the hull as I understand most transducers transmit a fairly wide beam. I guess that would effect the side-scanning features though, making the image lopsided. But, I don't really care. As you said, this is "bottom-only" usage...

Transducer inside hull
The transom-mount transducer on my 2018 North River RAIV loses bottom at any speed except slow ahead. I've lowered the transducer as far as it will go to try to reach clean water flow, without success. I've had a cheap transom-mount depth transducer siliconed INSIDE the hull of one of my fiber glass...

Re: Lubricant for rubber deck gaskets
I have one of those hatches on my North River RAIV. The gasket is clearish/opaque and feels like silicone to me but I guess it could be rubber. Couldn't it simply be lubricated with a little silicone grease?

Re: Corrosion on anode
Now THAT's interesting. I had thought some about how clean to make the interface from the anode to the tab on the transom. But now that you illustrate the issue better, I feel that I may need to put some extra effort into making sure that interface is as low-resistance (electrically) as possible.

Re: Corrosion on anode
Good question. I had to go back and check.
The anode in my photos is a 6x12 hull anode (A-24779 alloy?) which I purchased from BoatZincs.com and cut in half.

Re: Corrosion on anode
Thanks for commenting. The anode is aluminum (1/2" 6x12 plate I cut in half and drilled for mounting), and I think it's working wonderfully. Yes, it's protecting the whole boat, as I think intended by North River Boats. I replace the anode twice a year and it seems to be moderately active. The ...

Corrosion on anode
I know my anodes are supposed to be sacrificial and all but, I haven't seen them look like this before.
Is this just funny looking corrosion or something else?

Re: Heading sensor on alloy boat
Just because I haven't seen the addressed. Are you calibrating the compass on the water underway? Yes, underway calibration. I tried the calibration procedure again yesterday with no better results. At this point it's just an exercise in futility since the autopilot is working reasonably well even ...

Re: Heading sensor on alloy boat
Here's the installation below the floor of the helm area, looking aft. I guess I have to admit that the course computer being only a few inches away from the bilge pump wires is probably not good.

Re: Heading sensor on alloy boat
Is it consistent or all over the place? I’m not sure, I’ll have to experiment some more. It’s primarily the Garmin autopilot Calibration Value in the Dealer Setup menu which concerns me. It’s gives a number from 0 to 100, with 100 being a magnetically perfect environment. Mine is somewhere around t...

Heading sensor on alloy boat
I have a Garmin GHP Reactor autopilot on my North River RAIV with the course computer (heading sensor) mounted below the deck, under the helm area. It works but I’m not able to get very good compass calibration values. Am I fighting a losing battle with a metal boat or should I be looking for other ...

Re: Recent Chine Extrusion Experience
Kevin,
Any chance you could draw a simple diagram of what you're referring? I'm trying to picture the joint you're describing.
Also, I sent you a private message on this site. Did you receive it?
Many thanks from a new metal boat owner.

Re: RockSalt 34 Re-born
I spent some time drooling over the RockSalt that was for sale here in MA when it was at South Shore Dry Dock. Impressive boats!
I wish you the best in bringing plate boats to a wider audience here in the Northeast.
Will you be at the New England Boat Show?

I thank you all for helping me get to the point of having a plate aluminum boat. I recently took delivery of this 28'...

I'm still new to alloy boats but trying to learn as much as I can. I've been hoping to could find something small to start with, and stumbled across this little boat near me here in Massachusetts. Stopped and talked to the owner today and he is not interested in selling. But, he said the boat was bu...
