Moving Sounder into the hull

Finally did the deed today.

Marked up the hole.

Took a jigsaw to my lovely clean deck

This is what you find inside a ViperMax.

Then drilled a hole in the corner of the transom box into the adjoining cavity and fed a coat hanger wire through over the bulkhead to drag the cable through.

Pinched some plasticine from the kids and used it to create a well in the hull on top of the flat bit which is the planing pad then a few tubes of araldite to glue the sounder into the hull.

Fitted the Bomar hatch to close it all up again.

Not a job I want to have to do again

What's that stringer for Chris? The central one that the transducer is mounted next to. I thought it was part of a drain system for ensuring any water that gets trapped in the hull goes strainght to the transom end. Wish I'd paid more attention when I saw mine without the deck on.

Andy you are right it is a tunnel that is used to drain water throough to the back of the boat. it runs the length of the boat along the centreline and ends about 6" from the transom.

You can see it on the picture you posted although the picture has been take at a funny angle and it does not look like its on the centreline (ignore the red)

i am not sure if you hae done it, but would be a good idea to paint the exposed ply, from the cut out for the hatch, with some resin and flowcoat, or either, to seal it.

other wise water will get into your deck and you will get a 'soft area' which no one likes!!!

Thanks butty, I smeared sikaflex all round the exposed wood and used Sikaflex to seal the hatch to the deck.

If it is a drain channel, where does it drain from and too? There's no opening on the end of mine IIRC. (I purposely cut a hatch into the deck during my fit-out, partly to be able to check the biges for dryness and also as prep for a sounder at a later date)

I assumed it was a piece of timber acting as a kind of keel line for the moulding.

It definately looks like a tube, as seen in Chris's photo. I'm guessing here but I assume that it has holes drilled into it to allow water from any sealed compartment to drain into said tube and give clear access though the many bulkheads and straight to the transom area.

As a postscipt to this I took the boat out on Saturday for its first outing with the sonar relocated and was stunned at the performance, I was getting a signal even at 40 knots+ and at lower speeds none of the interference caused by the wash from the transom and prop that I used to suffer.

The definition on the fish finder screen is also strong without having to increase the sensitivity.

A definate must do for anyone who has inkling

Spec'ing a boat requires a great deal of thought and deliberation. Alternatively, spec'ing a boat in the French Alps on a snow covered slope, using a borrowed phone works quite well.

It would be so much more fun if he bought an RB.
