Sorry, still in building progress. But the new addition to our collection is this EPV 1.85m cat.
This time we are really going Xtreme.
This is the beginning of A F*cking lot of Dead batteries.
Peter and I had for some time the idea to build something very Xtreme,
and it had to be electric powered.Something most people not exactly would do. Up a given moment our eyes fell on this hull. at first Peter had the plan this build this boat with two Gas engines, till I suggested the idea to fire it with two brusless motors. After some research, we placed the first orders at several company's. after the first parts came in, we started with the building proces.
Below you can see how far we are in the building progress.

|---|---|
Firts we strength the hull with carbon fiber. |
And placed the drives and rudder on. |
|
|
In the front we put 3 pool noodles for float capacity. |
Here you see the motor mount in its first position. |
|
|
Made carbon plates were the drives comes mount on for extra strength. |
A steering servo plate is made and glue in. |
|
|
This is one of two speed controllers we are going to use. |
The drives in a closer view. |
|
|
All the hardware is placed. |
The motor plates are glue in with Carbon fiber. Also in front you can see the plate where later on a link comes on to hold the battery packs. |

Mounted the front bulkhead for additional strenght
Placed flotation behind this (3 poolnoodles in total)

During a SAW we organised here in the Netherlands we've had a big disaster. We run our bout with a top speed far above 100 km/h to one of the pile's where one of the sencors where on. |

The hull broke totaly open, and some parts came out. ( The reciever battery came with a speed of 90 km/h between the second pile. See the third picture below) |

One part of the hull is complete damaged, some parts of the electroniks and hadware sunk to the bottum of the lake. After getting allmost everything on shore, we desided that this was our most desater off all times. The hull is on repairable, the speed controllers have water damage. One drive is totaly curved. |
