Proper tube length is determined by tube ID and testing. Lots can be outside of the boat to get C of G correct. Either the tubes are outside or the boat is longer which adds more drag and weight. The steam has to cool and condense long before it reaches the end of the tube or the engine will not run or soon stop running. Reading about how a putt putt engine works will help you understand why. Thanks for watching and the comment. PP4V
Why is length of the tubes so long ? Especially outside the boat ! The tubes makes extra resistance and the steam is getting cooled off before it reach the end of the tubes.

@PuttPutt4video i was really flabbergasted that a very intense research is done on putt putt boats and each crafted so well . I ADMIRE ur HOBBY and DEDICATION. nice watching your video :)
nice you need to make one huge but light boat and add as many tubes as you can it would be really cool and fast.Or why dont you try to make a boat out ofthese tubes????
@TheDownloadfreegames Interesting thoughts. Some technical difficulties arise. The curves, length, diameter and quantity of tubes affect performance. Too many tubes bent into a boat shape would not likely be a better or lighter boat.. Drag from irregular hull shape and weight of method used to keep the tubes joined and watertight likely more than as done now. Like your way of thinking though.
@laranjo123 The design for building these boats out of one piece (mostly) of flat aluminum is basic. For a new boat it is only a matter of changing the measurements for LOA, beam and displacement etc. to get what I require for a new boat.
@888000777666 I really have not thought about it. In the end it is the buyer who sets the price. It would also depend on which boat. Which boat are you interested in?
@888000777666 As I have no real interest in selling at this time and the boat you mention has considerable extra work on the hull shape perhaps $350.00
The statesman and scientist Ben Franklin performed similar experiments to determine the best shape that would result in the greatest efficiency for canal boats. Penn State University runs a giant "water tunnel" that fill a building. It's fine to make hydrodynamic calculations, but they still test profiles in water for real-world results. Nice work.

There are several kinds of steam driven boats. These have no moving parts and yes, this is how they work.
