Can guarantee this will be a slow thread, and it can go any direction:) Will take some time and efforts but in the end most of my projects will get there, sooner or later…
First stage will be slightly off the topic here but i really need a easy test board and a base line to compare for further development of the e -version.
So what I will do first:, will run some tests using 3.5 hp outboard motors, that’s about 2,6 kw and trying to optimize hull and propeller around this power, at least for now. I have a small inflatable boat that clocked close to 24 kmh with that power, will get out of comfort zone and try to reach 30 kmh with this power. That will be a challenge, if even possible…
The test platform then? I have a inflatable sup…got an “great” idea(maybe not). Why not use that as plug?
Had some old polyester, light plywood and some epoxy …here we are. Some comments of the build:
- very stupid idea…next time will just use xps/ eps foam as a core
- will put zero effort on finish, will leave it at epoxy primer and not smooth anything with putty, this is just a tool for testing. Actually one spot is slightly smoothed, the spot where transom and bottom meet. To “let the water go” so to say, this must be sharp and is one of the most important place to get right when you are over hull speed.
Actually the sup shape is far from optimal, so to improve the “design” laminated the plug only partly of the full length to get a sharp stern. Still the sides curves in a bit but don think that matters too much in this case
Its easy to make some quick and dirty mods on the hull case needed (add some shape) as its pretty sturdy. Its huge so it also weights a bit guess 25 kg. There is a removable bolt on transom for the motor, will take some more pictures later.
