Limpet Mines look sort of like what you are describing, did you buy the boat at a Drug confiscation auction.

Sounds like a transducer.

Actually that does make the most sense...but it seems huge for that purpose..do they make transducers the size of a shoe box ? Is there anything inside a typical external depth transducer or are they solid metal ?

I think Capt Bill is right. Large 1 kw Transducers can look as you describe. Airmar makes the Chirp in several shapes and sizes including a "shoebox" looking critter

Perhaps, but I would think the people in a boatyard would recognize a transducer.

Man, those big ones are expensive. I hope he's right as the previous owner upgraded all the electronics about 4 or 5 years ago, including a new transducer (much smaller and more water dynamic shape). So I could have the yard just remove the thing and plug up the hole in the hull....but I need to be there when they do it in case some diamonds fall out....

Could it be some kind of sensor for a stabilizer or a stabilizer than didn't work out?

No......I do have usual Naiad stabilizers, but thinking everthing for those except the fins is inside.

It is indeed a transducer put there by CIA to be able to follow your boat via secret satellite. Didn't you know that the PO of your boat was pablo escobar? Now diamonds are becoming more and more plausible!

It's very clear for me.. it's a warp accelerator neutrino controlled... now you need to find the way to accelerate and brake before reach Jupiter..

PD: don't tell NASA you found one...

call viking and ask them? that boat was built in st Pete Florida i delivered a few of them to new York back in 1989, may be even yours? they were built in the old gulf star factory.

Actually no it wasn't....was built in NJ along with the convertible Vikings. But you are right that it's heritage is a Gulfstar 55. But by 1993 this was a new design....with bulwark bow, no bow pulpit, a day head near the galley and salon, and other changes.

Designed from the get go to be a cockpit motor yacht...but previous owner did extend the aft deck and added lots of storage under that deck accessable via doors in the cockpit. It even has a third control station, usable in the cockpit (behind the smallest door on the starboard side)

As to asking Viking...highly unlikely they would know....Lazarra might know. But I won't bother him with it.... I'll figure it out next time I visit the boat on the hard...probably this Wednesday.

Well, a water-maker does need to draw in seawater from which to produce your desalinated water, so it probably is an intake for that, with the strainer close in on the keel side (where you can't see) so it is less likely to suck in jellyfish and similar detritus. If it is not the intake for the water-maker, it has to b a possibly redundant sonar transducer, if there is no lead now connecting to it inside, I would suggest.

I now have a couple of those. Really annoyed me that newer sonars could no longer use the ones I had through the hull. To avoid more haul-outs to fit them, and more holes in the hull, my replacement transducers are all stuck to the inside of the hull in good places with black Sikaflex, and work fine, by the way, but I don't ever go in really deep water.

FWIW, I also have an inside depth transducer...round in shape....for a 1990's vintage digital depth display unit (forget the manuf)....which is sort of nice to confirm the much newer multi-function Raymarine color display is in agreement. Only annoyance is the older unit seems to have no backlight and kinda hard to read sometimes.

Hit it repeatedly with a big hammer. When the yard finishes repairing it, check back and let us know what it was.

Something must be connected to it on the inside of the boat - either a cable if it's a transducer, or a hose if it's an intake scoop/screen. You need to locate it on the inside of the boat.

it was not a new design the 63s and 74s had the same setup,they built all of the motor yachts down there the 44s 55s 63s 74s 82s then they shut it down and the boats that were not finished were run up to NJ with no interior and finished up there. somr layed around up there for 2 or three yrs
