Hi

this hull looks nice but is a little bit complicated to you. It was only an example.
Try to find any deep - vee hull made from fibre glass.

The lenght about 650 -700 mm.

Then buy two 6v batteries and marine ESC with water cooling inside. Find any aluminium rudder you can get or similiar made from reinforced plastic. Get your remote control in local hobby shop: two channel fm system ( Futaba ). Buy two props: 39 mm and 42 mm diameter.

If bought, put your hull on the water. Put all you have to the hull. Try to put 700 on the middle, and two batteries on each side of inner space of the hull. Think where to put receiver and ESC. Try to find a place for rudder servo.

Now, wait a second and try to make a thin line with waterproof marker to mark water line on the back, above the expected place for making hole for the shaft tube.

Maybe this method is primitive, but that's the simplest way of planning your first speed boat. Remember - you are going to use piercing prop. I did it many times and I was succeded.
