Paul, i, too, have had a failure of the sonic speed transducer but the new one - a much revised model Airmar I’m told - has been working flawlessly for 2 years.  If you do not have a BSP reading, you should check what the source of BSP is in the Settings Menu, likely under „system“  If it is the Airmar transducer, you should switch it to the paddle wheel (which is part of the depth and sea temp transducer, which is likely a dst200) and see whether you have BSP.   If you do, replace the sonic speed.  I would contact Stéphane at Pochon for this.  He may be able to get you a new one for free because the old one had known problems, but at least he will be able to tell you which type to get.  I’m not on the boat but can give you that info in late August if you still need it.   If you don’t see BSP with the paddle wheel either, you should check the other settings. Again, I can help in late August. 

You need BSP (or better yet, the drift corrected STW) to calculate the true wind direction and speed that you are seeing on the water - ie the wind speed and direction you need to make decisions whether to tack or gybe, for example, or to calibrate your wind instruments.  You could use SOG, but then you are calculating the TWD and TWS without any current effect and since the boat is sailing in the current, this will give you wrong info.    Even in the Med, current can make a significant difference.

Paul,

You are welcome. Some things are very difficult to sort out. Also, it is difficult to diagnose via email, but I am usually luckier than wrong.😀😀

To take this a step further. There are more than a few Amel owners who have lost SOW mostly because of faulty B&G Sonic Speed Sensors. A significant number of those do nothing because they say they have SOG on GPS. Without SOW, TWA and TWS are not accurate. Because I am not a smart sailor, I wanted and used TWA and TWS all of the time. TWA and TWS can be calculated using SOG, but you have to use a black box from A&T Electronics to convert the SOG data to SOW data before it is read by the B&G processor.

Thank you very much Bill, I just found the issue, you lead me to the SOW being the reference for wind and the SOG was not referenced or switched on in the H3000 set up so now it’s activated alls working. I must have switched it off along the way or there’s a gremlin lurking 

Thanks to all for the community support its a great help

Thank you Bill for the help, I have recently replaced the paddle wheel and as mentioned under motor the other day the issues seemed to rectify for the rest of that journey, with accurate wind and speed through the water, so I am now suspecting an intermittent issue as a possibility also.

I will be visiting Palma Mallorca early in the week so hopefully get a good B&G technician aboard 


Kind regards Paul

You mentioned that you have no SOW. My guess is either your Sonic Speed or Paddlewheel transducers are not working properly, or a defective H3000 processor.

Hello all,

im inquiring if someone can assist, my B&G H3000 has an issue with regards to displaying the TWS as the AWS and the AWA as the AWS so both are the same, with no displaying of the TWS. Also the boat speed is not displaying despite the paddle wheel being operable.

if I run the engine the displaying of the TWS and AWS and boat speed functions as normal but then when the engine is off and we are sailing the issue continues.

any assistance would be appreciated

There are indeed some awesome quotes here. Thanks so much for sharing. I have a new favorite now: “Waves are not measured in feet or inches, they are measured in increments of fear.” – Buzzy Trent

I have to laugh at the “Twenty years from now…” being attributed to Mark Twain. I see this all the time on peoples blogs and FaceBook etc. It is a motto so many cruisers use as the credo for their lifestyle. But, Mark Twain never actually said or wrote this. It has to be the most incorrectly attributed quote of all time.

The first time this quote ever appeared in print was pretty recently in 1990. It is in a book by the bestselling author H. Jackson Brown, Jr. He published the work containing the quotation, but he did not take credit for it. The book “P.S. I Love You” contained a collection of wise aphorisms from Brown’s mother, Sarah Frances Brown. Each page contained one thought, and this quote was printed on page 13. Each remark was prefaced with “P.S.” and ended with “I love you, Mom”. I guess attributing it to Mark Twain is more impactful than the actual person deserving of the credit, Sarah Frances Brown.

I got that quote from here.

There are some great sayings here.

Hi Paul

If you’re unable to solve the problem via the forum then Sarah at A&T (formerly Tinley Electronics) in Lymington, UK maybe able to help. Bill Rouse introduced me to them. They’ve built a business servicing B&G but also now provide their own processors and other kit which fully integrates with B&G but has the advantage of being fully serviceable. I plan to replace all my Nav electronics this winter and will explore A&T as the ‘hub’. My H3000 keeps ‘freezing’ - unnerving! 

Sarah is highly knowledgeable and helpful - Tel +44 1590 610071 or sarah@...

I’ve attached their product info. 

Best of luck.

There is not sufficient current when your engine doesn't run perhaps?
When your engine is running and everything is OK as expected the B&G H3000 seems to have no problems.
So a low electricity current might be the reason for that.
