Yes you will hit bottom at some point lol,
As for your Garmin, the 740s is pretty powerful, we had depth readings and clear view of the bottom in 2470 ' of water. Ours sometimes does what you are explaining. If you turn it off and on it clears itself. I think the issue stems from the transducer wire being close to lots of other wires.
Also try slowing down your rate of display or ping. Since sailboats go so much slower than powerboats it might help.

Guess Im not that lucky!
I'd suggest a bucket of prop wash.

What happens if you swing a live boat Kat around your head?

Re: will i go aground?

Why would you go aground if you are usng the GPS/electronic charts and the Radar. Being the Eagle draft is 6 ft, I make sure there is plenty of water under us based on our position. Very seldom do I even look at the depth sounder. the Eagle has two depth, just in cas one fails.

Also I tend to follow sail boats that have as deep a keel as the Eagle so if they can make it so should the Eagle. I have soft grounded the Eagle twice both intentional. At extreem low tides the Eagle goes grounded at our slip.

I assume that you are joking in the above.

Just in case you were serious, trusting charts, electronic or otherwise, to keep you from ever running aground will fail in so many parts of the world... charts are simply not that detailed or accurate in most of the waters of the world. Observation of the actual situation in real time is necessary, and a depth sounder is one of the crucial elements of such observations. A forward looking sonar is even better!

If your sailing (or motoring) life is in deep, well marked channels between marinas, perhaps your philosophy will suffice. If you are a cruiser, more challenging scenarios present themselves daily and other methodologies are necessary.

Cheers,

Jim

We boat in the PNW where the water is deep. With a 14+ ft tide swing, I also watch/time the tides. Nobeltec charts has a great tide/current similator.


I make sure I stay well in side the channels and do not cut buoys/corners. If not sure I wait and watch other boats, preferable sail boats.

Re: will i go aground?

I was once advised to follow a vessel with a deeper draft than yours.
