[Score: 6/10] 34"/10000g Maggie M Capable of 3mph and a runtime of 120mins Single Propellor (4 Blade 50mm) Direct Drive Powered by Lead Acid (6v) 12Amp/h Batteries - Comments: A Model Slipway Kit Built by my late father in law, Frank Ballard Runs well, handles Ok with its Becker Rudder and Kort Nozzle. Maybe time for a refit
Well Martin, its their loss. I try to make everything except the electrics. I suppose I'm lucky in being a retired prototype engineer, with my own machines and space to work. These days I am restoring more than building, I find it more challenging. Spotted a vintage boat in antique shop today, it had diesel marine power and valve and relay control system with a strange adjustable korts nozzle arrangement. I am trying to get the wife to let me buy it. Cheers Colin.
yes also building one A lot of work to complete yet. Fitted with 2x mfa 6/1 motors and bow thruster ,kort nozzle, becker rudders,all windows fitted with individual glazing a lot of time consuming, still a lot to do

Hi, I can't profess to be a Tug expert but I believe the general rule is 'Low revs & Hi Torque'. I hope one of the tug fans here will pick up this thread. Also this forum might be useful to you; a discussion on kort nozzles & tugs 'Fixed or steerable'. https://www.rcgroups.com/forums/showthread.php?1536288-Steer... Good luck, let us know how it goes. Cheers Doug 😎
I recently bought a on Ebay 'stranded' vintage harbourtug which will be fully rebuild. (I actually bought a NOS hull, and old - but good build - superstructure and all the deckgear & fittings. Except for some essential parts... There's no kortnozzle/rudder and propellor. I would like to know what size of nozzle and propdiameter I should mount. Originally it was designed with a steering nozzle/rudder, but the only item which comes close is the fixed nozzle as used on the Robbe Happy Hunter salvage tug model.(which has twin nozzles) That nozzle would be fixed with a seperate rudder for steering. What would you advise? What alternatives are available? (Making a proper nozzle myself which actually works and looks to scale is out of the question.) Attached three photos: one showing original (steering nozzle) and teh other with this Happy Hunter fixed nozzle, and te drawing showing the design.
Scratch Built 1:32 scale Dover Harbour Board Tug, DHB Doughty. The main hull is a standard Damen hull purchased from Mobile Marine Models, see their website for Portgarth. the hull is fitted with 2 x T12 Motors for the main propulsion,2 x 60 degree kort nozzles for steering, with 2 x purpose made brass props. Also fitted is a 12v Graupner water pump for the working fire monitor and Fwd spray bar, 2 x Mtronks 15 amp ESC's, Futaba steering servo and Futaba 40 MHz Receiver. Approx Dimensions including fendering Loa 41" Beam 14"

A bit vauqe about the fiqures because we are still on the slipway. It is scratch built from the Phil Thomas drawing "Shell Pioneer" Twin prop with Kort nozzle steering, bow thruster, working fire monitors and lights. Throtle & steering control via Action Electronics P40E mixer. 2x 2S25C4000mA lipoly's. 6 Ch radio (4 used). draws around 4.5A hope to get 30min run time minimum. Third ESC for bow thruster.
Modified HegI Fairplay V tug built by My late Father. Mods include bigger 65mm Prop in a brass kort nozzle, working fire monitors, lights, radar, engine sound and grappling hooks to rescue nitro boats. Built 1980-81.
Alan you are right they are from another thread this was just a quick option I will try & get the trawler out later it is up in the garage loft & take some pictures for you, as I remember the motor was amidships to allow room for a 12v battery the servo horn is straight to the kort nozzle rudder arm pleased to help if I can Bob 👍
