The case is not that hard like my carbon board. Weight is about 7kilos (only the case). The mast and as well the foils are in my opinion the more dangerous parts.

Do you plan to improve / modify your design further, and/or share more details of the conception?
I don’t know what we should change to be honest 
We can share the 3D of the stiffener. What else do you need?
I’ve got an RL mast as well and would like to print the setup you have with the motor mount and prop. Would you share files as I can’t seem to find anything online and I’m not great at Cad yet!
Well, I don’t understand how do you :
- waterproof the holes in the case for attaching the aluminium frame (I don’t get how the rivet help in waterproofing)
- how do you keep water from coming from the mast hole
- which tool do you use to fold the aluminium plate, and how did you calculate where to fold it so it fits perfectly the angles of the board
?
Si if you could share more pictures of the holes with rivets also from the outside so I can understand how it works that would be great !
Hi nicolaje
- to attach the aluminium frame we put M5 flathead screws (covered with innotec adhesive) through holes on the sides of both plastic and aluminium and secured them with self-locking nuts
- between mastplate and case is a thin sponge rubber plate to make it waterproof, also the motor cables are glued in the mastplate with innotec adhesive to prevent water coming through the mast
- the aluminium frame was manifactured by a local lasercutting companie, we “just” had to generate a precise 3d file (credits go to @superlefax
)
I hope these informations helped you, maybe i can take some pictures on the weekend to show you

Great build. helps a ton with chosing right parts for first build. What prop are you using? Is the 7" prop that Maytech and Flipsy package with their kits of any use? Can anyone share a list of sources for props that work well for efoil w/120Kv,14s and a larger wing (moses w1100, moses w950)
Aloha,
The say imitation is the highest form of flattery 
My first attempt at a build

It’s so cool that you are going the same route than us. The case looks massive Please keep us updated and show some more details. What is the weight of that tank ?
I’m really looking forward to that
The whole setup is about 64lbs. Went out for a morning test session
^ That’s my partner in crime
A very senior builder on the island gifted us the VESC mk6, it was cutting out at 120 amps. Its going to take a bit more current to get this barge to fly! My 5” PLA printed prop also may not be helping. I’ve got a 200 amp controller and will try to install this evening.

Did the case stay water proof? Which one did you use?
Hi the riflecase surfers,
actually, can you post more pictures ?
I would especially love to see the screws that link the base plate to the case and the mastplate etc… and if possible, have the .STEP or .part of the base or the whole assembly (spoiler : I want to 100% copy-paste you 
)
Hi @nicolaje: I gonna try to upload all the CAD data needed to Thingiverse today or tomorrow. Maybe @kotnascher can send some more pictures
May I suggest a folding bow to ease your take-offs and touch-downs ? During transport it can also stay inside the case. A triangular rib will stiffen the assembly.

Aloha,
No, it hasn’t stayed waterproof. To be fair, its a pretty old - well used, pelican case. I’d suggest starting from new like superlefax and kotnascher did.
Also - I need to build a new battery pack, may as well go ahead and do a 16s 9P 
. You guys know what’s going on with the Samsung 30q’s? They seem to be out of stock at many of the reputable sites & those that do have them are asking $6.50 - $7.00 each… ouch. Any ideas on safe alternatives?
Oh snap! I made our first YouTube video haha.
Stay tuned for more development.

Thank you so much !
I’m still affraid of this part:
You waterproof this by just puttin silicon on the screwhead ?
Also, how do you put a screw here, under the plate to fix the vertical bar, without it creating vertical offset / void between the case and the plate ?
Cheers
For the screws outside we used those ones with a bit silicon underneath the head:
Did you ever heard about countersunk screws ? I’m really looking forward to your build.
