Hi so work goes on

Next step is to laminate the Hull
For Laminating i used Carbon/Aramid Fabric 215 g/m² and Resin L with Hardener PH 161.This Maretials are all from R&G Germany.
First i layed the fabric on the Tunnel.
This takes several hours .
After this i made the upper side.
This work was very hard.
I had the resin all over my arms and also in the hairs

[Chris Nason]

That is going to be one hell of a machine

I'm really looking forward to see this come together. I've never seen these motors before, all the more exciting! What type of sandwich material was used on the deck and tunnel?

Sandwich material is Rohacell foam panels from R&G

So next step.
After the hull is laminated in the front i made the rest sandwich material on the tunnel.
Next work was to lay the fabric in the back on the downside.
After this i closed the holes at the rear end with 1,5mm carbon plates.
First i fixed the plates with superglue and than i lay the carbon/aramid fabric over it.
Last work was to lay the biggest piece of fabric in the middle of the boat.
The size of the piece was 100 to 120 zentimeters.

This boat will be a piece of art when it is finished! Nice work!

Hello

to make it complete is the next step to reinforce the cover.
First i closes the hole where normaly the air scoop is mounted.
For this i take a 1,5mm Carbon plate.
I fixed it with superglue.
After this i grind the cover insiede.
I reinforce the cover with the same fabric as the hull.
After the fabric is hardend i cut of the ride out fabric

Hi

next step is building the air scoop.

For building i got from my friend(who also builts a HPR 233) the original air scoop.
From this part i made for me a silicone mold.
This mold i filled up with epoxy.
After a few hours i take the scoop out of the mold.
It looks very good but the weight was to high.
So i decide to grind out the innside of the scoop.
Now the weigt of the scoop was reduced from 350 gramm to 120 gramm.
After this i glued inside a bolt for fasten the air scoop on the cover.
Than i fileld the sccop inside with 2K Foam from R&G

Air scoop ready

Hi Guys

next parts are the premenilary Motor mounts.

First i cut it out from a cardboard.This is very easy.

After this i transfer the cardboard template on a 6mm wood panel.
I cut out the two motor panels and i grind it that it match exactly in the hull.
For getting the right screw holes to fasten the motors on the panels a good Friend(Flo,he was at the last SAW in LA)
makes me a drill Template of aluminium.
After this the motors take first time a seat in the hull.

greetings from germany

Man those things look tiny inside that hull!! Sweet boat! Can't wait to see the finished result.

[Espresso]

Can you put the motors next to a soda/beer can so we can compare how big they are? They look pretty big/fat compared to a 3080.
