The mystery of the stuck anchor

- In this video I show how an anchor can easily get too stuck to retreive easily. After that Arn and I do a side-scan sonar search to find the likely location of a lost anchor and then Paul and I go for a SCUBA dive to try to find it.

I believe this should become established in maritime law. When boating near Dangar Island, if you pass Renko and she is moored and unattended, you must, without boarding, leave a full six pack onboard.
I have often thought of this exact gesture myself
What cool gesture may someone pay it forward to that person😉
That’s a perfect idea ! I’d give you 2 👍for that one ! Lol
you're god damn right.
May I add no bananas 😏
I like how you used the model to explain the chain situation. great video mate
Other than the dilemma of finding the anchor, my first impression (and from other videos) is how great that Detroit sounds!
My second impression is how great Renko looked in the early morning fog!
Love the chicken action, too.
Thanks Gene!
This episode is the perfect climax to the quixotic decision to restore Renko, and very satisfying it is to watch her in service. I thought the whole introduction to diving and salvage issues was great, treasure or not, and have every faith your underwater videography.
Thanks Cliff!
dude love the hammock on the boat they should be made mandatory on every boat built, i have watched every episode from day 1 and all i will say is enjoy you time in it mate you have earned every minute cheers from England
Thanks Ian!
I like the fact you guys sat down for a while after putting on your wetsuits., I do the same, after hooking up my trailer and strapping down my dirt bike driving to the park, putting on my riding gear, I sit there for 45 minutes to and hour before I start riding. Damn is sucks to get old.
Yes boss....but.."never say die"...👌👌👌👌👌
@Rene Drew Rene: I am thats why I am still riding dirt bikes at my age.
Great explanation on the anchor getting caught.
I believe that blunt ended dive knife is the sharpest knife we've seen on your channel.
That was a great explanation and a great scale demonstration of how it happens. I had never thought about that happening. Great episode!!
Thanks mate. 👍🏼
Even though you didn't find the anchor, on that occasion, it was very interesting to watch. I'm very much looking forward to when you get into the salvage and diving later on. Thanks Stu. cheers buddy and stay safe.
Know we know what we are up against we’ll get it next time!
A Dangar video on my birthday! What a present! Thanks, mate!
Happy birthday!
This is simply the loveliest boat channel there is, so well done and interesting. Great to watch while having a beer!
Wow, thank you!
Hey Stu, have you considered that a way to help those aching, creaking joints and get you started in the
morning would be to spray the affected area of the body with...... " Start Ya Bastard " ?
Lol.
The 'joys' of zero vis diving. A few of our local harbours are like this. I always dive on an incoming tide - cleaner water and the current moves the silt away.
I heard the current moves you away too
Thanks Stu!! good to see the model Renko at work !!
Thanks Thomas, worked a treat! :)
Another great video. I must say that I’m always gobsmacked just how beautiful it is where you live!
Thanks mate, glad you liked it. :)
Fascinating as always Stu! Got my dive ticket with the same mob in 98' at Port Stephens.
Great part of the world. (#1 lesson: no drinkies before a dive)
I am loving your videos, you’ve done a smooth transition from just building /fixing the boat to new adventures. Always looking forward to them. And the chicken ending of the week :))
Awesome, thank you!
This is awesome Stu !!! Finally using Renko for her purpose in life!! Really enjoyed this video!!
Thanks mate. :)
I love that you don't have to blur the details of your licence!
free beers are always a welcome treat! Gratz on the new gear, keep the videos coming....
Signing off a video with you, with a clean face, a huge smile, relaxing on the boat. That is just awesome.
Love the model! Very cool.
It's funny you were worried about leaving a buoy when the anchor initially got snagged. Here in New England there would already be 485,000 lobster trap buoys everywhere - in the channel, out of the channel, near shore, far from shore, no matter! It's like driving your boat through a mine field.
Couldn't help thinking that you were risking Renko's anchor the same way.
Really interesting, thanks.
Wouldn’t be hard to find our own anchor given it would still be attached to the boat!
Oh the sweet sound of the Detroit Diesel! Watching the build was fun. The dives look like they might be funner - for you too.
Hey Stu, after finishing my Open Water yesterday, I now know what the heck you were doing when getting ready for your dive. Best of luck searching for the anchor.
Thanks mate and glad to hear you got your ticket! :)
Very good model example😀Have never seen anything being explaind so good, with such degree of small teaspoons without being ironic or boring💪 😀
Glad it was helpful!
MiniRenko floats nicely Stu! :)
Another great video. I am glad to see that I am not the only one that has wetsuit issues. I have found that mine shrink when left out of the water for a long time! Realy should try and get wet more often. Hope you find the anchor. Look forward to the next episode! Cheers mate!
Thanks mate. I hope we find it too!
Great video Stu love the model boat of Renko great demonstration hope you find the lost Anchor cheers ⚓️⚓️⚓️⚓️⚓️⚓️⚓️⚓️⚓️
Thanks mate!
Daisy and Daffy Turned in to see their seed tree capture... and a brilliant first salvage ... tune the gear... experience the bottom love that stuff thanks Stu....next time I'll drop a twelve pack.
Thanks Frank! :)
Agreed the model video was awesome in showing how it happens 👏
Loving the new 'using the boat' videos Stu. I was at Brooklyn pub today for lunch.
Thanks Iain, hope you enjoyed the pub visit. :)
I enjoyed watching your cute chickens Stu!!!! Just as much as the actual diving vid!!! LOL!!! Cheers & Beers 2 u~!~
Thanks mate. :)
Hi Stu. That was cool to watch. And relevant too. Yes, I have a mystery on my river - just like you. Its best described as 'The mystery of the Yamaha 90 and, 2 x 10 meter control cables, and electrical harness extension. Yes, all that kit that fell off my transom at WOT. My first inkling that something was going down was the feeling of whipping cables running past mt legs and feet. As far as I can work out, someone had removed the fasteners in order to burgle my Outboard.
.BTW, Don't worry mate, have got my respect. Watching your mission has given me a laugh and the heart to keep up my search albeit in the Tamaki River Haystack
In terms of progress so far, Ive only got as far as 3-4 hours of random passes, whilst recording my side scan data of the rivers silty bottom. ' I know she's down there and Im just glad I'm not down there with the outboard. Dodging a bullet is always a happy ending.
Bugger, sorry to hear that happened. The trick with sunk outboards is to get them running as soon as you can after getting them to the surface. Good luck!
This adventure was fun, at least for watching. I feel your pain on the getting older nonsense! Mine is with all the layers of winter gear. The idea with the guide rope weighted at both ends might work, maybe have another rope connected with a ring so it can slide along the fixed rope. That would allow you to explore up and down the terrain, and hopefully not get terribly tangled. Or, maybe attach a metal detector to the ROV? It could become some kind of mad science/engineering experiment.
😂 The hammock is looking a fine addition Stu!
Loving the content.
Have a good weekend.👍
Thanks, you too!
Great video Stu. Thanks!
A1A on getting an anchor out ...including just cutting the chain !! Good Stuff !! Thank You !!
I watched this sitting in a hammock - a fine addition to any location.
Stu dons wetsuit, moves around deck and I am instantly transported to my boyhood watching a Thunderbirds episode.
One of the rare situations where Thunderbird 4 would be deployed.
Another great episode! Love the Tenacious D shirt!
Thanks again!
Nice Tenacious D shirt, love the videos.
Thanks!
A couple of beers always clears things up! For me anyhow. I never tackle anything without a beer.
A handy tool for low vis diving is a tank strobe so you can keep an eye on your buddy! Did a lot of muck diving in sean river in perth and they work well!
Would like to get a handful for sure.
I really enjoyed the video and it's nice to see you are finally getting to enjoy the fruits of all the hard labor you put into this endeavor.
The model was spot on great job!!!!
A friend of mine is a surface supplied salvage diver, we have done several jobs here in NM. Getting him dressed is fun because he is wearing insulated bib and a sweat shirt under his dry suit . Talk about silty jobs we went to retrieve a sailboat in a high mountain lake, Mike found it by running into it! All our camera showed was silt right in front of the camera
That’s certainly the way it goes sometimes!
Hi Stu, great video. Next time your in that situation with no GPS plotter. Take a picture from your phone I'm sure if you go into the photo location it give you GPS coordinates / location, from where you took the photo.
Great idea. :)
Hopefully I will head down past Dangar island in the future and say G'day.
Oy!, I love seeing you starting all your vids from the wheelhouse, the active wheelhouse. Good on ya, Stu.
Excellent 👌👍. All that work getting her working is now beginning to pay off
Love that Diesel Sound.... Old us Navy Sailor...
One thing I have discovered when searching for things is that you will always find it in the last place you look !
Underwater searching hardly ever goes to plan though and you always have to revise your methods to suit the location, it's almost impossible to follow any kind of pattern at times so you will need to be extremely lucky to spot what you are searching for. You will always find more fishing gear than what you set out to find too !
I always keep looking after I find something so it isn’t in the last place I look. ;)
Brillant video mate, your videos are always a bright spot in my day!
Looking forward to the successful completion of the mystery and realizing the location is strangely different from your memory. It’s not only physical slippage but mental happening with age :)
It will be interesting to see where it ends up being.
My dive ticket (NAUI) was first issued in 1974. I recertified (PADI) in 1996. Deepest dive on air was a bounce dive to 80 metres. Deepest free dive and free ascent was 30 metres in Small Hope Bay, Bahamas.
80 metres is huge!
Fantastic to see the boat working as intended! Big like on this one Stu. Congrats in defeat. Cheers.
ahoy Dangar, nice to see you
Stu, one thing id recommend, especially since your doing more work related things, and less sight seeing with your dives, is moving from a "yoke" style 1st stage, to a "DIN" style. the thread in connection on the DIN is much stronger, and less likely to get knocked loose if you bump the top of the tank, or get entangled in something. most manufactures make kits to convert the regulator from one style to another, so you wouldn't need a new reg, just a few parts. Ive also found they tend to have less issues with making a good seal, unlike the yoke style.
I agree. And the O-ring is in the reg not the tank so it's harder to lose.
I guess one approach, when first cutting away the anchor chain, is to attach a small buff on a short rope to it, so that it's well below the surface but floats high enough off the bottom for the diver to find it; if there's a worry it'll be carried away by a passing boat. Anyway, good hunting for your anchor.
Interesting dive.
Got my 'ticket' (open ocean) May 1972
I learned a cheap trick to help slide into dive suits. Slip disposable cheap market bags over your feet. Used it to pass the USCG timed survival suit donning test.
We use diluted hair conditioner to slip into our wet suits. Works a treat.
And you and your suit stay smelling nice. Some of us reckon the sharks hate the smell too...... can’t confirm that though
Interesting tip!
Interesting project....a couple of points; (hope you dont mind the input)
ROV's are great but if vis is low it may prove pointless and with the topography and tidal current may also prove quite difficult/hazardous to navigate especially with the tether....your anchor recovery could easily turn into an ROV recovery project.
There are a couple of other basic options to underwater search survey the area.....comes down to planning.....determine estimated dive time/bottom time and then estimate/predict search area which can be covered in time available/budgeted. Then choose methodology.
1 - Concentric circles tried - determined not suitable
2 - Compass /bearing line search from central point - connect tether to central point choose a bearing (usually start at 0 degrees mag) and extend search swimming that bearing predetermined distance, return on reverse bearing .... collecting tether along the way. Then rotate to next bearing 2-5 degrees magnetic (this depends on search conditions and visibility) and repeat (work area like bicycle spokes). This allows you to search/cover ground through difficult terrain in a systematic method.
3 - Establish baseline transect, a line (marked at intervals like every two meters) from central point (float anchor point) to a predetermined point (usually 0 degrees mag) at a predetermined distance (peg it to the bottom) and run straight search transects parralell from that base line (at 90/270 degrees magnetic).
There are many other ways, too many to note, but fundementally it is about making an educated guess where to start (using all information you can gather....grid survey the broad search area with you sounder could provide a reference), knowing where you have searched so you don't waste time, having a simple easy to execute plan....cause thinking is hard, and using a repeatable method that is effecient and safe.
Don't forget to carry a tag line to possitively mark where the anchor or chain is if you find it (can use the tether but sometime you find more than you bargin on).
Yes, I think searching along compass bearings could be the way to go. We’ll search again soon!
Hahaha.. I can relate to the wetsuit issue. Felt the same when I tried to squeeze into mine on the last dive. Love the card photo, I remember that one. :)
Want to get you out for dive next time you are on Australia Dayne. I’ll take the boat up to Hervey Bay for you! :)
@@DangarMarine Warp Factor Zero! :)
It was really nice to see you go an entire episode without an angle grinder, even having a bit of fun. I forgot which hen it was that went broody a while back, but next time maybe you can slip a couple of fertile eggs under her; two hens does not a flock make.
Thanks mate. Yes, they do need a few extra friends.
that is a fancy sonarplotterthingy you got there! :)
Brownie Points for the Tenacious D Tshirt mate!
Tenacious Stu and the Anchor of Destiny!
Could be the title of the follow up video. :)
Nice to see you use Renco as you planned. This was a good start. You worked hard to get here and well deserved. If you get a chance read the book Marine Salvage by Joseph N. Gores. It is an old book that came out 1971. Fascinating read. 👍🇺🇸
Great video. Thanks.
Try magnet fishing for the chain. If you get a hit and can partially pull it up its probably a chain. Then use the rope attached to the magnet as a guide when you dive. Just a thought. Love the show mate!
It will be interesting to try with the magnet.
Use a big magnet fish for the chain
I love the tenacious D shirt
Hey stew, after a bit of recon with the rover, try looking on the flat with the Excalibur. The chain will likely be laid out in a line. Search in lines 90°to the run of the tide.
Yes, will build a better picture some the riverbed with the sonar then identify some good areas to detect.
Good video, and love the chooks 👍🏻
Nice Tenacious D shirt! Awesome 👍
Mate this was really good stuff....Thanks very much...Cheers State side Kentucky over and out..!
Stu
I see you added a hammock on Renko. Looks like a great place to relax after wiggling out of that suit .🤔💯💯💯💯💯💯💯💯
I have no doubt you're going to find that anchor.
Thanks Michael!
Suggestion, put a small buoy on your anchor in case it gets stuck so you can locate it. We did that a few times when anchoring in rocky areas.
Interesting to see you were certified (ticket) in 1996. I received my scuba certification in 1971. LOL
I forget how old I am until something like this reminds me
I thought this was a really cool video on the channel. I came for the boating stuff originally, and that's got me really interested in to the mechanical aspects of boats now. But I LOVE diving and I feel like I can never find dive-related videos that are right for me. I know how to dive and love seeing the different details of stuff, and I feel like there aren't any vlog-style-ish channels that cover content how I like. I definitely look forward to more videos on this! There's also two other things I've wanted to say, but haven't commented yet. First, in the last month of and a half of summer (in the northern hemisphere...) watching pretty much all your videos on Renko, and it's been really cool to see you getting the boat, redoing everything, and now finally getting to use it regularly. Second, I was wondering if you've thought about putting some mapping-software on the touch-screen computer that you could use to map your sonar scans. Some sort of GIS software would work, maybe reefmaster-pro does that, or if you don't mind getting a little more technical you can use QGIS probably (it's free). I worked in a lab that was mapping the harbor by my university, and one of the things the graduate student did was overlay all these sidescan transects of miles of shoreline using ArcGIS. Not that you'd need to do that, but I thought something along those lines might be useful for search projects like these, or just interesting for many reasons in general.
Thanks mate. I’d love to get some mapping software working on the computer so we could slowly build up a very detailed survey of the river bed around the island. I would be very interested in doing that.
Before you cut the chain, get a GPS fix from your chartplotter. Makes it really easy to find the anchor or rock back.
@Dangarmarine hey Stu a suggestion you could make a clamp to attach a flashlight to the metal detector so you have a free hand. Instead of using two like you were. Would be a handy little gadget. Love the dive video. More please!
Could be a good way to go for sure.
Thinking it may be a good idea to put some handles out the edge of that entrance to the boat
Always clearer at the top of the tide.
Yeah, unfortunately that day the high tide wasn’t until close to dark.
A hook made up out of 1/4 or 3/8 steel is good for reaching through the silt I had one with a T handle in timber so when you do the search you bury and drag the hook back as you proceed. Tough as you say when there's those rocks!!
I left an anchor in a lake and another in the ocean after they got stuck. I had to leave quickly as the winds were picking up and the swells were getting big. I carried a "Crocodile Dundee" type knife at the steering wheel for quick cuts of the anchor rope.
Great video I enjoyed it.
I did quite a few "lost anchor searches" back in the day (visual, no metal detecting gear). My one comment about that is .. a lost anchor is very hard to find. You would think it should be easy to spot with the chain and rode hanging off it, but it never seems to work that way. Unless you drop right on top of it, searches are too often non productive. BTW: my dive certification is 29 years prior to yours (time flies, eh?). The standard tank back then was steel 72 cu ft @ 2250 psi. My "high tech" rig had twin 72's with a custom manifold that had 2 regulator ports so I could have a second reg for emergencies. That rig was very heavy. I don't think I could even pick it up today.
For sure finding anything underwater is much harder than most people realise. I’m looking forwArd to practicing and get better at it though.
Fun episode Stu, pretty lifeless down there. I so wanna try magnet fishing for the chain.
You bring the beer I’ll bring the Magnet. :)
@@DangarMarine Im off beer but still like magnets
Cool video. It was exciting watching the search dive! Is there such a thing as negative visibility 'cause damn that looked rough! Stu, the downward pointing 2D sonar (3D side scan could be used in overlay mode if the Raymarine offers it like my Lowrance unit does) could resolve a pattern like a stretched out chain (and the chain pile formed when you cut the chain) if it is not buried too deeply into the silt. You can adjust the contrast and gain on the sonar and that will help distinguish higher density materials from lower. Worth considering anyway. Good luck with the search. Cheers!
Hahaha love the anchoring simulation
You can always lay out a grid of jack stay lines for searching instead of using a circular pattern.
Good explanation on the use of knifes in diving. Just think about the location of the knife if you become entangled the leg is often the hardest place to reach for your knife.
Need a proper extended pulpit on the bow of Renko for handling the anchor easily and it looks good too !
All that was A M A Z I N G 👌🏻
Memories, I used to buddy Scuba haha was a bit like that at times ☝🏻 Ive learn a lot more about anchoring etc ☝🏻💪🏻🏆
Thanks mate!
Your videos are great and varied so I think that’s why we all seem to love and appreciate them but ultimately they come from you and your blessed willingness to help people🏆
Praying you are always kept safe now champ🙏🏻stay well!
Anchor your circle search 5 m off bottom so your line wont snag as much
I’m 64 years old with bad knees, as I watched Paul climb back onboard my knees were killing me.
