Both these are mounted on solid laminate and require no hole in the boat and don’t have a problem with bottom growth, which I like.
As Jedi mentioned, doesn’t work mounting inside a hull if shooting through core. You can cut away the inner skin, de core and build up the laminate from the inside if one wants to have a depth sounder mounted on the inside of a cored hull.

Yes. I don’t know if it’s clear or not but that’s what I did. Mine was mounted in liquid Epoxy because that was the latest internet consensus. Didn’t work at any water depth for me. Makes the clicking sound, doesn’t return a depth reading.

Yeah, just wasn’t sure if you have a core below waterline or not. Mounting in a small tub of mineral spirits no doubt made ours more sensitive than mounted in the epoxy.

Sheaves not right. Slightly bigger than ordered.

Options:

1) leave out the spacer plates between sheaves having them slightly loose (but are bronze on stainless)

2) jam in with spacers and they don’t turn well.


I’m thinking #1….

I do. I’m sure your method worked better since mine didn’t work at all. Lol

The core is almost certainly the issue. Removing the core in a section would allow the shoot through setup to work.

[s/v Jedi]

Back in post #445 I explained that a transducer shooting through the hull only works without a core. Every installation instruction has that in big boldface print. Why is everything so difficult?

Lashings, done many times many pages back. I guess I need a break from this thread.

You've demonstrated great patience so for.

Yes. Everyone knows that you don’t shoot through the core when shooting through the hull. No one has questioned that in the entire thread. Standard procedure. I don’t know why you keep saying that. Over and over and over again I have said that I put mine in liquid epoxy. This has to be the third or fourth time I have said that in the past few pages. I installed my through the hull sounder eight years ago. I’m not sure why everyone is talking about it. I didn’t ask a single question about sounders in this thread. This is a standing rigging thread. Maybe I need a break also ha ha.

Temporary lashings were somewhat unclear since 3 different people said 3 different things. 2 of them are professional riggers who own rigging shops, so I’m not throwing out their advice. Im listening to all.

Bowline to shrouds, then lashings with the bitter ends after a few loops seems good. I just don’t know how to do the lashings and things are not loading well. Im getting severely deprioritized and can’t load a pdf today. So I’m just trying to see how to do and terminate the lashings, which the yacht rigger was going to send a video of, but got too busy.

Nothing is as complicated as it’s being made out to be.

Oops! Sorry Chotu. Stupid Hurricane Idalia got me distracted. I can still do the video if you need me to?

It’s ok. You got busy. That’s a good thing. Can’t be doing a bunch of remedial pro-bono work. Ha ha.

Only if you think of doing it and are bored. I just don’t understand the steps of the lashing part to finish up. Definitely do real, paying work and don’t worry about me.

I don’t understand why no one is reading my posts.

I said that I put it in liquid epoxy 5 times now. There is no core. It was in liquid epoxy. I’m not even asking anything about transducers. But for some reason everyone’s talking about them. Why?

Jedi introduced the topic of transducers by saying I need to run a transducer wire through the main structural bulkhead (he was thinking of a monohull). I responded that I don’t have to run it there and it’s nowhere near the centerline of my boat. That’s it.

I’ve had my transducer installed for 8 years now. I got a free forward scan sonar from a promo. I’m trying that out. That’s all that’s going on.

I asked nothing about transducers, I have no questions about them. I have one that’s been installed in liquid epoxy for 8 years. It doesn’t work. It has nothing to do with this thread.

My brain hurts. Why is everyone talking about transducers?

Feeling like I need a break too

There, this is the first time you write that you have no core. Previously you said you did, see attachment.

Smj: not sure if you have a core.
Chotu: I do and it doesn’t work at all

No core on the very bottom

[Chotu]

OK. To clear up the confusion, let me explain some details. Then can we please drop the talk about transducers? I had no questions about transducers. I asked nothing at all about them at all.

My boat’s laminate schedule:

————
36oz triax
25mm (1inch) corecell
36oz triax
————-


All 36oz triax has the uni fibers running uninterrupted from the bow to the stern.

Locally, there are some high density foam areas and extra fiberglass layers as needed.

For instance, in the keel area, there is an extra 24oz biax tape outside the hull on top of other layers of extra 24oz tape both inside the hull and outside. All of that glass is around 1” corecell.

The transducer is in the forward starboard hull. It’s in an area that has been decored with a hole saw and then liquid epoxy poured in to mount the transducer. It doesn’t work.

My theory is in 100 degree northern Florida heat, the big lump of epoxy overheated a little bit and got bubbles in it. There is no direct evidence of this, but what else could it be, really?

Now, Can we please stop talking about transducers? This has nothing to do with standing rigging. All I was doing was obliging the conversation about them. But it is become quite a negative on the thread. It has frustrated both jedi and myself. Lol and probably everyone else.

I would really prefer to talk about the standing rigging in here. Not only that, I don’t even have questions about transducers. You guys just want to talk about them. But maybe we should make a new thread to chat about them. I don’t know.
