Thanks 
ok, the surface is very simply worked by gluing the different parts together with epoxy resin + microballoon before laying either fiberglass or carbon fiber in the same way as you did for your board. Nothing too complicated.
1st time in water to see if everything is tight. Check
Sealing for mastplate as on board V1 molded with Wagnerseal
Last step now building the battery packs:4x 8S6P to get 2x 16S6P
As Molicel P42 was sold out, I took Samsung INR21700-50S 5000mAh - 35A

Hot wire was not so fine this time. There will be a lot of filling and sanding
One last step of filling and then glassing.

Today maidenflight after testing of watertightness.
Starting is more challenging as on the 120cm board, once in the air it feels good. I think there will be a lot of fun in 2025

awesome builds! what hatch are you using?
Thank You!
It‘s the Osculati round inspection hatch. Size I think is 230mm. It‘s the biggest one.
It‘s 100% watertight. For opening after foiling you Need a Special tool as a lever

What kind of tool? Can you 3d print it?
Yes, I have 1 3D printed and one made out of wood
Would you mind sharing the 3d printed tool to open it?
Next time on the PC I can Upload to Thingiverse.
But I prefere the wooden one.

It was qick´n´dirty, not nice, but is woking.
You have to screw it on a wooden stick for example to have a longer lever
