Im not sure if Martin or one of the admins could copy this bit of the post to make a 2nd entry as a seperate topic.
I do own a steam boat but not in the same sence as what others here whould think, many years ago when i first started learning the skills of GPR i decided the only real way to learn was to build a boat from GPR so i looked at suitable engines to power a small boat (15cms in length) i found all sorts of micro motors etc but i felt that something else wan needed, ( more on that in a moment)
I first looked around the shops a for suitable kit that i could mod it, plenty of them but i came across a plastic bath toy boat froma cheap shop the hull was quite good for the application so i brought it £1 bargin, took it home, now no one laugh this was the first boat i every built and more so the first grp moulded boat i ever made...
got the boat home took a box and mounted the plastic hull of the boat i just brough in it, i then processed to pour in 4kg of mixed up plaster... at a cost of £10 getting expencive now,..
next let it set ( took 9 days!!) once dry flipped my mould up and removed the plastic boat which i cleaned off and was good as new,
next up was making the boat i took the mould and procedded to cut some strips of matting and placed them in the mould and then using a brush painted the resin over the matting i did this twice so it was pretty thick and heavy. i used some fastglas from halfords £20 for a 5kg pack it was the smallest they had there.
2 coats of matting and resin dried in about 30 mins and i procedded to pop the gpf hull out of the mould.. and whooops! i didnt know i had to use a realase agent so in removing the hull i had to destoy that mould

after popping out the new hull it needed a clean up nothing major.
ok engine time.. i remember back in school the process for 'flash steam' and looked around for systems of a flash steam boiler and came across an old method of creating flash steam nick named 'pop pop boats' or put put boats, apparently and old school method for making an old tobacco tin into a boat used by the scouts as far back as they can remember.
so next job was to look for an engine, i never found one separably only in tin boats that you had to purchase, so i built my own engine. using 5mm copper tubing i neaded the metal into a few coils and then added some lengths as the entry and exit points.
i drilled a few holes in the back of the boat and mounted the engine place with some resin and made a stand for the fuel source, which would be a tea candle.
next up i made a hull deck and a superstructure of a type ( remember this is my first boat i ever built so it wasn't going to look pretty) i gpr the superstructure and deck and painted it.
put it in the bath and lit a candle and waited .. and waited.. about 2 mins went buy and sudden it burst to life pop pop pop pop and the boat thrusted forward! bingo my first ever steam engine boat..
And now some pics of it be kind it was the first boat i ever built!




and thats as far as i have ever come to owning a steam powered boat but one day
