The transducer has to "see" water and the only way that can happen is
if it's in contact with the water.

Not true.

There are plenty of intallations where the transducer is mounted inside a
fiberglass hull and shoots through the hull. The last three boats I have
owned were set up that way. It definately cuts down the range it can reach,
but it doesn't need to be wet.

I am not sure how well it would work shooting through an aluminum hull.
It's easy to try, however. Just take a small tube of RTV and squeeze it out
into a puddle on the inside of the hull. (it would be best to clean the
hull first so it will get a good stick). Rock the transducer down into the
puddle, being carefull to avoid trapping any air. Just "moosh" it down into
the puddle.

Now see if it works. If it works okay, let the RTV cure and your all set.
If it doesn't work, pull it up before right away.



However, do you need a depth finder? If you can beach a 60 foot boat,
there can't be much draft to the vessel making the whole point of a
depth finder mute.


I sure don't follow your reasoning. There are times that I might beach a
houseboat, but I would do it very carefully. The outdrives will still
require a few feet of depth for operation, just like any boat. I wouldn't
want to hit my props on a houseboat any more than I would any boat.

I was thinking that if you 'beach' a 60' boat, a through hull
would be the least of your worries. :^)

Around the places I fish in CT and RI, beaching a boat would be a more
or less permanent installation. :)

I was thinking Cape Cod beaching where you run the boat right up on
the beach.

Of course now that I think about it, your approach would be more
reasonable.

You are correct.

I misspoke.

Ever seen Izaak Walton's recipe for cooking a whole pike? To die for! Or
from. Lots of butter.

Is done all the time with houseboats in Lake Mead and Lake Powell. Run the
bow on to the beach and an anchor off the stern. Run a gangplank down to
the beach to go ashore. I have an aluminum river jetboat and the transducer
is on a plate on the transom and just kicks up if you get too shallow. Run
over a small sandbar, or park the boat on top of a gravel bar. Gravel bar
is worst. Smashed one chine flat. $175 to repair.

That one must have escaped me somewhere along the line.

Yep: we see the houseboaters doing that all the time on lake Lanier.
Looks like a good way to spend the day :-)

Yep, that's pretty much the idea. My reasoning behind the DF was that
Lake Lanier varies a lot by year in it's water height and where an
island that is now 5' underwater could next week be 2' underwater. If
I had a DF near the bow then I would be able to see the island rising
and turn to avoid it. As to beaching, as you said, the front is shoved
up about 7 feet onto the shore and then stern lines are attached to
trees at 45 degree angles to prevent the stern from swinging up onto
the beach.
