Its possible we have all had this issue.. boat in the middle of the pond not working, I used one of the other boats I have to retrieve it, not very easy.. I am thinking of building a rescue vessel, square(ish) front, twin prop's and rudders tucked out the way for reversing and with soft rubber edging all around it to push or even guide (if damaged rudder) any boat back to shore.. or is this going a bit far?.. your thoughts or what you do when or if this happens when your out on the pond?

Maybe something like this!

Or I've heard of plastic tubing being use as well!

Couldn't have said it better myself Martin , we do have a 2 seater rescue boat that we use for our meetings but generally we use one of the members tug boats to do the rescue.

I do think the rescue dinghy is the best idea, but of course that is a club thing, organisationally and financially.
I guess the OP wants to assure himself he can rescue his own boat with something suitable when it's only him on the water. Fair enough. A tug is a nice idea IF you can get a tow line aboard the stricken vessel, so I suppose the all embracing lobster claw style has potential. A floating Brabham BT 34 comes to mind.

Cheers,
Martin

I've been pondering a neodymium magnet on a derrick on the stern of my Southampton tug and steel plates set into the foredecks of my boat and ships! Still pondering, reeling in with a winch is easy, running out the cable to drop the magnet down onto the boat is causing me mechanical headaches though. 😡 Maybe just raising and lowering a suitable boom would be easier!? Any ideas folks, especially amongst you winch using sailors?

First time my destroyer conked out I swam out 'in me knickers' to rescue it cos the wind was pushing it towards the lake fountains. It's NOT a flying boat! Got a round of applause and some interesting suggestions from some of the er 'ladies' present 😲😉
Second time we had flat calm on a balmy summer evening and she started very slowly drifting home.
So as it was early evening we went to the lakeside restaurant terrace where I could enjoy a steak and a glass or two while keeping an eye on her progress. Hard life ain't it 😉
Whatever, I'm sure there's a more elegant solution than more plumbing than there is in my bathroom! I even once used my sharp pointed destroyer to push a failed plastic RTR so called speed boat home. Took a lot of manoeuvring with a long thin destroyer but we made it.
Once I managed to get it lined up and close enough to shore a good shove with all ahead flank then full astern let it run up the shore.
Was good helmsmanship practise.
A simple shaped rubber block I could hang over the bow would have made it much easier!
Cheers all, don't get stuck! Doug 😎
PS One other 'Schnapps idea' as they might call it here in Bavaria, I've been playing with for a while is a model of the 'Big Lifter'.
It's a conveyor ship like a big powered dry dock. To take on the load she floods huge tanks and sinks herself😲 slides under the load, pumps the water out again and up she comes load an' all! Would be fun wouldn't it?😉 All the bridge and accommodation superstructure and engine rooms are in the stern. At the bow there are only two tall towers for guidance when taking on the load. The rest is just flat loading deck. Sounds simple don' it 😁 an' a lot more fun than half the plumbing dept. of B&Q. 👍
PPS: I also tried the grab claw idea of Martin's. A sort of 4 prong grappling hook. As he rightly said the first snag is to get the line aboard the stricken vessel in the first place.
I tried it with one of the depth charge derricks on the stern of my destroyer. Reeling in - fine. Getting the line out ? Another kettle of fish. I considered a spring-loaded system to fire the line out IF I could make the winch free run to pay out!
Got no further than considering (the spring launcher I still have) before I completely stripped out the destroyer for a total refit.
Thinks, thinks, thinks ......

Hi All
This is my idea which fits on a number of boats.

Easy Doug. Ever heard of a pawl and gear. Have a free running motor and gear wheel with enough weight on the line to pull the line off the pulley if the pawl is lifted and no power to the motor. the weight will pull off line from a decent diameter drum and the motor turning backwards.Line pays out with the magnet's weight.Once contact is made the pawl( spring loaded ) is released after enough length of towline is achieved. This re-engages the pawl and stops the motor and drum turning. Power then applied to motor again as needed to recover line. Gear ratio may need playing with for best results. Suggest 2:1 for starters. likewise drum diameter for best results. Get the idea? A derrick would be needed for reach of course.
P.S.I don't get the "it's not a flying boat " bit though.Why would we imagine it was?😜😋🤔👍

Evenin' John, yes I do understand the pawl concept👍
problem is the weight😲 The magnets are very light. I even tried casting a lump of lead on top of it. nix!
I came to the conclusion I needed something like a tin o' baked beans to weight the line 🤔
Still fiddlin'. Hope never dies😉
Re 'Flying boat: if my destroyer had gone into the powerful fountains it would have been propelled up to about 60 feet at least 😭

I built a tug just for the purpose of rescuing, powered vessels are no problem at all, but I rescue more yachts than anything else.
Have rescued everything from a Micro Magic to a Marblehead.

Here's a pic of my tug bringing home an RG65, sticky rubber tyres on the side help. 😁

I think I have found what I think is what I am looking for, a Springer push tug...

Morning Doug Yes gotcha. I was thinking heavy magnet like a speaker magnet. OR arrange a relay with a double throw switch to reverse the current and hence the motor. Piece of P-ss for you mate.Just have enough weight to avoid tangles as you strip the line from the reel and fine synthetic string better than fishing line. It is less likely to be pinched in the roll on the drum. Also more scale.You may want a speed controller or esc perhaps. Or just rely on the gear ratio. An old brushed motor would do I think with about 4volts.You may still need a pawl to prevent the load stripping line when power is off the motor. I hope I tickled your little grey cells mon ami. Bon chance👍

Indeed you have John👍
if I get time today I'll dig out the winch I used for the trials on my destroyer, only operational boat at the time! Trouble with a destroyer - the stern is so low you can't reach the deck of most boats😲
I had also built a reversible ESC for the winch, a hefty commercial job with about a 385 motor I think. Ran on 6V.
Now I have the Southampton tug I was thinking of a much higher derrick, or A frame, on the stern!? Have some 0.5mm nylon line for the tow line, what do you think?
As an electronic engineer I sometimes need help with the mechanicals - which others seem to find sooooo easy 😲
Have right now a mechanical problem to solve on my Gina 2 fish cutter - more on that in the Blog. Cheers, Doug 😎

I have had this problem several times myself especially with fast electrics when they "flip" over. At present I take my old Aerokits Sea Commander with me to use as a rescue boat but there is always some element of difficulty when trying to line it up with the upturned craft.

How you deal with it depends on the size of your boating lake.
On small ones it is possible to have a vertical pole mounted on the bank with a long length of string attached to it. You then roll out the string and walk round until the string makes contact with your boat then slowly walk back bringing the boat to the side.

Building a rescue craft like you describe is perfectly normal as I have seen them from time to time and also you see them on You Tube when retrieving usually (you guess it), a fast electric in distress.

Good luck with your project and you can also disguise your "rescue boat" to look like a pusher tug etc.😁

boaty... something that hasn't occurred to me and it came to mind due to what you have mentioned, there are fishing rod's (or fishing pole's) that extend to quite some distance, I think the idea is so you don't disturb the fish from casting out...
