Mike,
Search for the thread pingers and resquebuoyes, there i've posted my vid.

Good stuff Manfred. I'd love to see a photo of your buoy, the spool and the servo switch etc.Leave a comment:

Tom,
As for using the wfly failsave, the instant failsave is too direct, i did made a conversion using this at my V80, added some electronics giving me a delay in releasing the buoye, using the failsave of the adf is the best method, less complicated.

Yes, Manfred as always great advice, I will look into it. The only issue I can see is with the wFly programming on the RX, there is zero delay when there is a signal loss. So, will definitely need to use Kevin's failsafe.Leave a comment:

Mike, i made a instruction vid at my youtube channel some time ago, all my boats have a requebuoy, wether this can be made commercially, it will depend on the type of boat.As for the stuff needed, i always use the failsave of the adf, add one more servo and make a mechanical lockingdevice connected to the servo, the failsave of the adf will give you a 3 second delay, the buoy is made from styrodure foam, i always try to hide this under a hatch at the aft part of my boats.It will take some weeks before i get back to the cave since i'm on travel, when i return i'll tackle the XXIII buoye system.
Tom,
Building a resquebuoye is the easiest way, on all occasions she popped up, giving me the location of my boat, once your boat is in deep water, gas won't help you, the boat is squeezed together by waterpressure, giving you a much smaller volume, at least not enough to get her to float to the surface.Only mistake i made in the past was, i left the line too short, about 10 mtrs, now these days i spool it up to 25 mtrs, why?, on some occasions your boat will be some distance from the shore, you can use a fishingrod to retrieve the line.

As I have read old SubCommittee Reports and watched old seminar recordings (including David's), everything from dropping weight, to buoy, to alkaseltzer type tablets have been used. I am finding nothing new under the sun it seems mechanically, but I think after my recent loss, it is worth re-investigating and look into some "old" school technology. As much as getting away from gas would be nice, it does work well!Leave a comment:

I think, in the wrong hands, this means of boat location, identification and retrieval is a great way of losing the boat to a fouled propeller.

Here's a rather interesting gadget http://equipped.outdoors.org/2010/06...-buoy.html?m=1. Wonder if it work with a sub?
Uses the same ingredients in bath bombs to generate CO2 gas.
Hmmm, Would it be possible to put some of this powder inside a small dissolvable container inside the ballast tank that will release gas after an elapsed length of time?
The amount of gas would need to be sufficient to surface the boat though. According to this post 1gm of NaHCO3 will procduce about 290cc of CO2 http://antoine.frostburg.edu/chem/se...ing-soda.shtml.
Need to do an actual experiment to determine how much gas a certain amount of powder really produces.Last edited by redboat219; 07-24-2014, 06:55 AM.Leave a comment:

If you haven't already, could you post some details of your buoy. I happen to think its a great idea and worth commercialising.
ThanksLeave a comment:

Yes boats have been succesfully recovered because of having a pinger on board.Leave a comment:

Loosing a boat is part of the risks we take when driving in open water, it's very sad you've lost her Tom, almost happened to me last year with the type 212, just like David described, dove too deep and lost the positive bouyency.
The added bouysystem saved my day, wheeled her in like a fish, when i return back home i'll place a bouy system also into my type XXIII, made allready some provisions for this in the past.

And they have successfully located and recovered a boat using this?Leave a comment:

The less sound, the lower the power consumption, so that would make sense. 5 second interval is adequate IMO, and don't forget as I pointed out earlier, sound travels much more effectively through water than through air.Leave a comment:
