Two years ago, while participating in one of our clubs events, A club member, and a friend, had gifted me a classic DUMAS Chris Craft Cobra. It was a welcome gift. Yet plagued with problems , right after another. It was basically broken out of the box, and marginally not safe to drive. IT plowed water, rode low, and was a death trap, when going into reverse. It would and flood, eventually sank. And almost two years later it was fished out by another club member, and took three weeks to restore. It became my daily driver 6 months ago, and is officially one of my best running boats. It become known as the "Phoenix," because it basically came back from the dead, and was returned as a much better boat. It's got some kiddy' up, and is 4S ready. ON 3 S. I'm skirting 30 MPH, from a 2000 KV. motor.
The build history is unknown. We don't know who the original builder was. Only that it changed owners at least 4 times. ME being 3 and 4. It was basically , the boat came back to me , after I was the one who lost in the first place . NOW, it's resting on my table, fully restored. THE photos , were of the restore process, and the first day back in the water.
I was there the day it visited Davy Jones Locker!
Super glad you got it back, and with the help of a talented fellow club member it was made sea worthy again!

Weather was perfect tonight for a test, so I did the 15km trip out to the Gulf harbour pond (most weed free pond) to throw the boat in. After a thorough under water hull inspection from the marine department, she was off. Everything worked ok except the silicone drive tube which had become enlarged due to soaking in the grease coming out the front of the jet shaft. It was slipping badly and probably losing about 60% of its' thrust. Manoeuvrability is excellent but reverse leaves a bit to be be desired. Steering in reverse is perfect but the thrust is not going forwards enough from the bucket. Might have to build in some nozzles to direct it better.
Smoke air and water are working as well as can be expected, (smoke is a bit wafty, but with too much air introduced it will disappear as it gets thinned out too much to see) I was not expecting miracles as this was a bit of an experiment (modified cheap jet unit with unknown abilities) but at least it shows promise😁. If I can find a coupling which is concentric it will solve the drive problem.
Trouble is, the Chinese insist on making a 4mm shaft, 4.95 (or whatever) which is useless for balance in a 4mm ID bearing for example. Fine for cars, but no good for boats or planes due to balance requirements (it's a mission trying to balance plane props due to this thinking,- they do it with everything) shafts for electric motors are a nightmare at times as the play they build in, can ruin an otherwise good motor. I might have to buy a flexible rubber/nylon universal or a collet style( preferable as these take up any undersize on shafts) to fix it. They included a spiral alloy one with the jet unit which is as loose as a rooster in a sock, and only good for slower things like 3D printers etc. One of these days they will learn how to machine things to fit.😐
Seemed to work a whole lot better in the tank for some reason Martin. Possibly due to the coupling slipping, (the squealing is it slipping) Just a bit of silicone fuel tube. I use it on all the boats as it's quiet, self aligning, and lets go if your prop gets jammed by weed. Problem is with the jet, it has a flat on the shaft for some reason which doesn't help the tube grip, and lets grease in causing slippage. I'll sort it eventually,- didn't expect miracles first time out (same with planes) - Almost always some small initial problems.
Motor should be spinning at 15,000 rpm with a 3 cell, but performance is not matching that, obviously,- just piddling along😁 Mind you, I used to cruise like that in the full sized boat, as the Zodiac motor used to suck gas like nothing at 20 knots plus, (gallons per mile, not miles per gallon!)
This video is taken from 2 different vessels with cameras, there are multiple salvages and a few crashes 😊
This will be the last video from Hubertus for an unknown amount of time due to the CoronaVirus my Government has shut down all nonessential services including clubs.
Two models seen at the Plymouth Gin Factory in the Barbican. Whilst there I had to sample the product and chose the Plymouth Navy Gin, which is gunpowder proof at over 57% and like drinking a single malt compared to a blend. Recommended. We were in Plymouth for the IMASS shipwreck conference the next day, which ranged from Byzantine to WW1 Naval shipwrecks, including HMS Hampshire and HMS Vanguard.
These two boats were tied up at a dock on Lake Coeur d’Alene, idaho. My nephew sent me the pictures. Tomorrow he will try to get the names of the boats and maybe information.
Hi Brian
The hull is very similar to the Tarpon produced in the 1960's, especially the four portholes on the raised deck.
The cabin is different but this could be a later addition/modification.
I did think it may have been a Dumas kit but I have scant knowledge of their range and was hoping one of our American friends would comment.
It certainly looks the part and I hope you have many hours of happy sailing.
Hi,
I know this was a long time ago but only just saw this, and you may have found the answer by now. It is a design by John L Langford called Margaret and was published in a book of drawings from Brown, Son and Ferguson in Glasgow. I think the drawings are still available and I bought a set years ago- never got built!
The hull was 48" long. Lovely boat.
All the best,
Ian
This is Serenity (AKA) Jersey City, she is a reworked and renamed 1:32 scale Tugboat. she measures in at 36" X 9"or 915mm X 229mm her weight is unknown (?) but I estimate it at about 7.5lbs to 9.0lbs give or take some ounces. Serenity is named after my Grand Daughter who is my pride and joy!
An ebay buy now fully restored custom made and commercial fittings. Power unit Electric manufactyrer and voltage unknown it will soon be time to test it on the water
Mate , lovely to hear , I felt a bit poorly somewhat going at you as over the top, which was unwarranted. I ran my vessel the last two weekends with my mates at the Lake Illawarra channel ( see google maps?) South of Wollongong New South Wales Australia. Well we are just a bunch of old boaties , sick of clubs and fights and restrictions/ rules/ flat earthers. We have a lot of public look at us and the Council Ranger and staff lookeee see at times , but AS we are in zone of the Lake Channel HiGH/ LOW tidal mark any authorities do not want to know us. Here in OZ you can still boat as we have a lack of ponds in the land (not like your WW2 type ponds built in villages for water for vehicle fire tenders from FIRE and bombing raids). We have extensions on household insurance in OZ to cover liability and we tell any noisy race/race boat types to ".... off". We sail 1 meters etc thames barge, steam and electric and i/c and all big stuff we ALL run together on the water on the "pond", old sets 27 40 and 2.4 gig. And I spelt Peter Dimberline incorrectly with a T , so he will find out and knuckle me!! I do clean the engine bay with motor car degreaser spray and the decks cabin etc with household Kitchen cleaner and paper wipes. Such is good old Dulux house paint over the years. Fold down f'wrd mast , crane sits in a brass tube at the port engine bay ,rear mast sits on a peg at stern, rear stbd hatch opens, ALL to avoid knocks breakages of bits and over the years I have actually cast alloy bits in plaster-moulds and screwed down with brass. Just a standard red plastic graupner 40 mm prop (4mm thread?) this motor is a SC china copy ? of a OS40 I think , I just run her at the first plane to look nice, no rev head stuff as not necessary, wide turns, but goes so well in 2 inch to 4 inch chop no pounding/ bone shaking during winter runs as it HAS to perform SCALE on the pond rather than toy boat behaviour such as dig in and flick turns and she is heavy to handle waves! Just standard home made fuel 4 to 1 and my mates talked me out of Castor, so now I use synthetic lube . We share all things. Too much talkie . All the best and just fly out to join us good weather too .
Here are a few pics of my Scout which wwas originally built in 1958, but left in my parents loft when I left home in 1966, but thankfully still there when my Mum asked me to clear the attic for insulation installers last year.
So far have cleaned it and fitted a MabuchI Brushed motor of unknown power, but appears to work well at 6Volts running a 2 blade plastic prop 30mm 'S' type.
Havent got round to fitting radio gear yet, so have done tests as a free sailer, setting rudder on a slow arc and watching as I walk round pond.Will update as soon as next stage is complete.
Thanks and no restoration work yet, but may have to coat hull as some seepage at joints.Will hopefully be able to keep model integraty without too much trouble.
HI Fellow Modellers,
Another model from the RADMC fleet at the fleetshaven workshop and boat yard in Ponthir.This model was built from a Caldercraft Kit, This model came into my possession for the price of 20p, a raffle prize at Bryn Bach Model Clubs OPen Day 2010, when it was built is unknown. The item being made for display use and not finished off, no internal electronic fixtures. Did have a prop shaft and prop that had not been fitted correctly. 50% of all the fixtures had to be removed and refitted before they fell off, some didn't stay in place from the show back home. The model was finised off using a photo of the Milford star on the internet. The fish boxes and figures being obtained off DON one of the Society members who had a mould to make them in white metal, only required cleaning up and finishing off. A graupner 6 volt steam unit is fitted in the funnel and to make the boat a little more realistic on the water,a maplin steam sound system has been used to generate the sound of the engine. A simple mod allows the revs to be linked to the engine voltage. The drive motor is a 550 with the lowest revs I had in MJB's this was married up to a 2.5/1 gearbox I also had in stock. The main motor and steam unit are supplied from a 7.2 volt nicad racing pack. This model has had meny fishing trips on Cwmbran Boating Lake and at shows the Society visit. Hope you enjoy the pictures, Regards GreyWolf.
More before and after and on the water ( video grab from video taken by minI cam on PT boat) There is another minI cam in the helm position on the launch looking through the screen.
A few more photos of before and after. it's possibly an Aerokit, Dumas or similar from he 60s or 70s. Have also added a new shaft along with the other bits.
