F-Ribs And Sibs - Inflatable Boat Community

I’m gonna use Steve’s transducer setup, the question is does the transducer have to be below the trim pads so it has a clear view the length of the boat.

It doesn’t need a view up the boat so much as to be in reasonably clean water - ie not turbulent. It also needs to remain below the waterline. As you increase your speed so the waterline behind the transom changes until it is at or below the trim tabs when you are on the plane.

Short answer - the bottom of the transducer should be below the tab.

Thanks Chris, that means I’m gonna have to make a bracket & attach it to the wood to lower it.
Tis is how it is at the moment.

Yeah, I would say that wants to come down a smidge. Second piece of wood underneath should do it!

Hi Mitch

Since I sent you that photo, I’ve used the boat quite a bit and was really impressed with the bracket. It’s easy on / off, twists when required to enable the boat to be beached, and more importantly appears to work well with the fish finder / chart plotter!

Looks like you’ve got yours sorted too. It’s not that clear from my pic, but the transducer is just below the trim tab (as Chris said), so hope that helps finalising your design?

I’m going to change the metal clips on mine for nylon ones; due to saltwater use, they’ve already corroded.

Good luck and hope it works out for you too

That looks great what sort of clips are they?

They’re tool clips or metal spring clips but as Steve stated they do rust out so I’ll be using some plastic waste pipe slit length ways so it clips over the wheel arm.

if you look at donny on youtube he has his transducer mounted in a box the transducer picks up the sonic pulse from inside the boat
