outboard steam launch
Looking for a new project i decided to try to make an outboard steam launch. The engine and drive took a while to work out but in the end it all came together well. The boat travels at a nice speed fueled by tablets for lightness as the boiler and engine are quite heavy for the boat size which is about 22"long. There is a brief glimpse of my paddle steamer that i also made. Pictures taken at TILFORD rural life museum Farnham. Next show is Easter Saturday Les Breame

    The tablets are the same ones used in all MAMOD toys after they stopped using meths.Get them from DREAM STEAM under name MSS Mamod Solid Fuel Tablets. They are not liked by many as they are quite toxic in confined spaces so dont use them indoors!!! For small boats they are great as they weigh nothing and give good heat. Les Breame

    Really good. What is her length? Cheers
  • lesliebreameChief Petty Officer 1st Class
    Hull is about 36" long and from ORION Mouldings[i think !!] its quite nice and shows all the rivets in good detail. We are at present making a Puffer 54" long and i am going to make the hull from soldered tinplate[ i hope !!! ] Les Breame

turbine
Hull is from boot sale. Turbine is 3" dia and is driven by twin boilers. I made them both. Speed is not blistering but it goes !!! Boiler pressure is 100lb/sq in. Les Breame

KD Perkasa
I acquired this boat part built some months ago through Dave M.
I have not put too much scale in detail but I am quite pleased with the overall finish. it is powered by two brushless 1250KV out runners and in the first sea trials I used 12v lead acid batteries. (That video was posted a few weeks ago - mdlbt.com/26793).
This video shows its second sea trial after I was persuaded to use lipos. The difference in performance is very pleasing.
Thank you Dave M for your help and advice during the build.

    Thank you for your compliments.
    This is in fact my second Perkasa. I built the first one about 40 years ago (see photo), before the introduction of the GRP hull. Losing interest in the hobby some years later, I sold the boat and have lived to regret it. (I was also the proud owner of a 37" Aerokits Crash Tender powered by a Frog 2.49cc diesel. That went the same way!)
    The first boat was quite lively powered by a Merco 61 i/c engine.
    No pictures of either I'm afraid.
    Hindsight is a wonderful thing.

    Hi Edward, its a fine balancing act of electrolysis to hydroide gas, compression then ignition but utillising vacuum formation as an assisting force to the power stroke so effectively making it a one stroke which sounds odd.still in development ive tried turbine,oscillator pistons and hydraulic recoil as end movers but the best seems to be the straight reciprocator. its scary,how the hell can they tax water??? cheers Neil.

Norstar Wave Princess
Built this Wave Princess 30 years ago meaning to use it with my children. Languished in attic since and now retired going to resurrect her for Grandchildren and would welcome any advice on motor size, prop shaft length, Propeller size etc etc. Picked up an as new MacGregor Digimac 111 transmitter receiver and servos at Boot Sale for £5, seems fitting I should use it for the old girl.
