I will continue this thread for further updates......
Sorry for inconvenience.

So here I started with HD thermocole of width 2.5cm .
And made layered body for the boat.

@pranavk09,
Looks good!
And super light.

It will probably be 99% out of the water.
Hence danger of being top heavy with the motor on top.
Can be compensated by heavy lipo as low as possible in the hull.

You can also consider making another one of these, and making it a twin hull catamaran.
Motor can be mounted on the cross braces connecting the hulls.
Single air rudder in the center, or twin water rudders on hulls...

Just one caution:
A high mounted motor/prop on a super light hull, will tend to dig its nose in when you increase power.

But more important, build whatever catches your fancy. Then you can build variants.
Good start. Best wishes.

Thanks a lot sir......

I applied over night glue on the hull.
And now installed all the electronics today.
Made an rudder from coro.

Auw - 380 Gms
Motor-2822 (1100 kV)
ESC - 30A
Servo- 9gm
Lipo - 3s 2200mAh
Prop - 6*4
Material used :- HD termocole

Yes sir it is exactly as you said.
Tried in a tub it was totally floating.
Will try to put the battery inside hull.

Angle the motor upwards.
It will counter the effect of motor on the boat.
The boat will appear to be 'nose heavy' on the application of power if the configuration you have shared is used.
Regards

  this is good idea
I was going to put battery inside
