Just to start off, pic of the Thalia. This is a small 110 ton vessel that is embedded into the seabed as far aft as the wheelhouse. the stern and engine dechouse are clearly visible even though it lies in 52m of water and isn't a particularly large ship

That's not the watch I lost is it?

[Lets go boating]

wow thats amazing

[gossy]

i must be missing something ..... prob too much sauvignon blanc ce soir

That was just the deepest scan so far at 52m and the wreck was picked up well enough to pick out detail. Its easier if you have dived it and know what the wreck actually looks like. I was quite impressed to pick up something so small at such a depth using a hull mounted transducer. I would like to see others that are deeper if they can be done as I am sure they can.
Next time I may take a run over a local wreck in 90m that is 6000grt and see what gets picked up!
this may be easier for those non divers out there as its considerably shallower and much larger at around 4000grt.

Bruce, love the pics, there are loads of vessels named thalia, do you have a link to a pic before it went down?

also any more underwater wreck pictures??

keep them coming!!

Thalia (ex Protector)

Golden Gift, wooden drifter in about 16m. You can just make out the ghostly outline of the wooden hull which has rotted away leaving parts of the metal superstructure and mechanical parts on the seabed.

amazing, you just have to know how to read them , ive often wondered if there is anything that you can dangle over the side of the rib that will give you really clear and vivid pictures of whats underneath as you trawl along, years ago i used to dive a lot, did the torry canyon and some other wrecks etc and it is fascinating, is there anything on the market without spending millions?? keep the pics coming!!

[BruceB]

I am at an advantage as I have dived all of the marks scanned at the weekend. This was deliberate as I wanted to check what I knew to be on the seabed with what the scans showed.
The next flat calm day I am off to look for new wrecks

Bruce - these are really impressive. Do you need to drive the boat back and forth to build up the image or do you stay still and the device does the magic? How long does it take to create an image? As I don't dive I won't ever be able to justify this for myself - but its amazing how much you can pick out. If you know what you are looking for can you spot these wrecks with an ordinary fishfinder?

Here are our ones from a current project: http://www.corribcharts.com/sidescan_images.html

I think the pipe is fantastic, any more?

Polwart, you just troll along in a straight line around 4-6knots and the pictures comes up as the boat passes the seabed. All the shots shown are screenshots of the actual view as the boat goes along.

The Thalia I found by using an ordinary sounder and running up and down for three months till I literally ran right over the top of it. With this kit I could have found it in a few hours.
If you know where the are you can pick them up on a sounder without any problem.

Are the results very sea state dependent? Can the system cope with a bit of a swell?

Cheers

[BruceB]

Because it is hull mounted and the boat isn't so big the sea state is fairly important.
I have been out trawling around about three times in the last fortnight and think I have found another Catalina. I would have dived it to confirm today but the wind got up as we were coming back from a picnic on a beach in the sun on Morvern . it is now so foggy the foghorns are going on Lismore and that is pretty rare
This one is slightly deeper and aircraft, because of the small size and condition of them, don't show up very well below about 20m or so.

Bruce,

You are fast becoming a repository of wrecks, you could sell this info! and not give it away for free - Side Scan Position pimp?

[markymarkP]

can you flag up the specs on the kit you were using, the pictures are great, i would love to see about a simular set up

[oracle]

Hi Bruce,

What sort of sea state have you been able to work up to and still get useable results?

Cheers

A little contribution... its an awesome little machine:-)

Could have gone a little faster over it.
