Thanks for this, from a fellow Navigator owner. I've been looking at it. I did talk to a surveyor about it, and he said one of the things needed is a solid hull. It can't be a cored hull because it won't carry the ultrasound past a balsa cored hull , like some of the Cruisers Inc. boats, I was told. Love the channel. You guys are spot on with some of the endemic issues, like the head fans! Safe sailing!
I have been very curious about these. Thank you for making this awesome independent review. I long since thought these were a type of snake oil. I probably don’t need one since I keep my boat in the freshwater. But if I ever decide to do some extended travel in saltwater, I would definitely consider these now.
Thank you! You have excellent content. Your delivery is engaging and helpful. You don’t waste time. Your repetition is intentional and helpful. You are a good thinker which gives me confidence in what you have to say. You both do an excellent job. I enjoy watching the rapport between you. A couple that enjoy boating with each other. Imagine that. I’m looking forward to your follow up on this product.
Off topic here. You’ve been living onboard for a bit now. Curious if would you do it now that you’ve had some experience? Is there anything you miss from a land home? Is there anything you’d change? We were looking at doing the same back when you made your move then changed our mind. Now we’re reconsidering it again.
Sounds great. So if I understand you correctly you have 2 transducers in the bow area, 2 on the hull in the ER and 2 on the engines, so a total of 6 ? What kind of wiring do you need to extend it all the way to the bow ? And maybe a strange question, but does the sound have any effect on animals ? We have dogs onboard and they might be able to hear the sound, don't want to scare or annoy them all day long.
If this worked as shown everyone would be buying one. I'm so skeptical every other review I see people say it didn't work for them and their dog hates the sound. I'm in for a bottom painting next week.
What kind of paint did you use on the running gear? With primer, 2 coats of Interlux and hull shield, I still get growth. I am in SW Florida, so there is that.
Good question! We haven’t seen any interference with fish finders. It does give off a ‘chirp’ every few seconds, which I would probably be annoying when you’re sleeping, if it was too close to your bunks.
I would rather pay the $2k with a ROI of less than 2 years even if I were paying only a $100 a month for a diver. The bottom line is does it work??? I guess we will wait to see your results. Great content ty
Thank you, my biggest issue is having to constantly brush the motor mounts and trim tabs (I have twin outboards) I also brush the water line every other week which unfortunately also removes the ablative paint. Definitely a first world problem 😂
6’ away. I will note these transducers just send out an ultrasonic pulse to the hull/rudder/running gear that microorganisms don’t care for. Kinda like Oprah music at the 7/11 keeping the kids away. It doesn’t send a focused signal like a depth sounder so, I wouldn’t expect (educated guess) that the two would interfere with each other.
My experience system works for hull but not so well for bow/stern thrusters or keel. The transducer on the thrusters were not effective as the gear oil and gears absorbed too much of the sound. On my boat the keel is too much mass for the sound waves to prevent growth. Here is a video review that I did, there is a link to an update. Plan to do another update in a few weeks. ruclips.net/video/9Syf3YqY7QU/видео.htmlsi=_LNXSxGRRPutuOXv
I would assume with a good bottom paint and no ultrasound system your hull would look the same because you have cleaned it 5 times. The purpose of these expensive gadgets and coatings like copper coat are that you dont have to clean it. Our hull has less growth than the boat in front of us who has copper coat and neither of us clean the hull and both use the boats about the same amount. Coppercoat is a waste of money in my opinion and the ultrasonic system sending constant vibration thru everything is not something i would want on my boat, i think it could produce failures in parts/systems that would not normally fail.
The rudders were the components that were protected in that test. Not the hull. The rudders were not cleaned. That said, if anyone has doubts about the ultrasonic system, I’d recommend against it. However, claiming that a 20kHz to 45kHz pulse would break your mechanicals or electrical is a reach. If anything it would reduce lubrication sludge or fuel deposits in mechanicals. Think ultrasonic cleaning.
@@theelliotts3840 I'd love to find a $100 diver. In CA on our 38 foot boat it is about $400. That does include some zincs and full running gear scraping. Had a cheaper diver years ago. Then we hauled out. Never touched the gear. It was a mess.
@@MVPaneeVino I've had 2 divers in 2 different marinas in Southen California and I paid $100 for the 27 during the pandemic and pay $150 for my 36 currently. Bottom paint is about $3000 every few years.

In Florida, you need the diver 2x/mo when it’s warm, around 9 months, and monthly when the water cools.
Good information! That’s crazy!
What do divers charge in your area?
@ About $2/ft. Some people don’t want to have it done 2x/mo but they get charged more.
Agreed, Im Ft Lauderdale, have a 68’ and have it done 2x monthly $350. includes 14’ tender. I’m looking into the system.
Well worth the money if just on the running gear. Please do a long term update.

Interesting. What is the material your hull?
Would this induce additional wear on metal to metal parts in the running gear, gearbox, etc?
Keep us posted, great product if it works as advertised
Will do!

Disconnect one of the rudder transducers for a while and then compare the 2 rudders.
That’s a good idea

No one is telling you to do anything, just sharing an experience. Have a safe and productive haul.
Great news will look them up
Interested to know how you attached transducer to the rudder.
I filed the rudder arm clean, sanded the bottom of the transducer and JB Weld’ed it on. The epoxy filled the gap in the center of the arm.
Good info; thank you sir
You bet!
What kind of paint did you use on the running gear? With primer, 2 coats of Interlux and hull shield, I still get growth. I am in SW Florida, so there is that.
Sea Hawk Sharkskin
Great Info! I just sold my first born for Propspeed.
Awesome ...been wondering about that
Thanks! These long term reviews are never my strength.
So it will not work on a 48 Volt system? Or can you add something to take it down to 24 Volt?
They recommend a Victron DC converter. 48V to 12V
I wonder if it's really a possible use on a 40 meter superyacht.
Does it have any effect on fishfinders etc?
Good question! We haven’t seen any interference with fish finders. It does give off a ‘chirp’ every few seconds, which I would probably be annoying when you’re sleeping, if it was too close to your bunks.
@@theelliotts3840 Thank you for your quick reply. How far are the Hull Shield transducers from your fishfinder transducer?

I have found the waterline sill gets slime. It still needs a brush while washing the boat.

Great review! Beautiful Kadey. How did your stabilizer fins fare? Did the shafts insulate the pulse or did they stay clean?
@@ElliYacht1ok, light algae growth which easily wipes off

Obviously this guy is trying to justify the costs. Must work for the company.
Dude, don’t buy it. It’s just a review.
Your monthly estimate for a 50 foot powerboat at $400 a month is crazy. It’s about $100 a month in California.
That’s a deal. Washington is a lot more expensive. At $100 per dive, I’d never consider these

@ that’s a hell of a price. Much more here in the Bay Area.
@ here’s my last one :
R-2 shaft zincs. 18.00 ea. 2 ea. 36.00
R-3 rudder tab zincs 24.00 ea. 48.00
1 1/2 shaft zinc anodes. 2 ea 28.00 ea. 56.00
Zinc install 90.00
Bottom clean 5$ ft. 190.00
