Hi @ all,

i'd like to present you my latest board.
It's an directional board without volume.

The shape is based on the North Nugget, but a little bit longer and with more width.

The materials are Palownia wood, 2 french pinewood stringers, carbon and glass.

Did you vacuum bag it, or did a hand layup? Not sure from the photos.
How thick is it / how is the flex?
Does it hold any rocker? It looks realy flat!

I don't believe fins will hold long! As you also might noticed, the grain direction you chose brakes like a cookie. Voids don't help either. Fin is under a lot of stress and exposed to hit something under water. They look nice though.

I don't know :D
At the moment we have very bad and cold weather (2°C).
I hope I can test it this Saturday, if the sun is shining.

I build by hand layup.
It was my first directional and I wouldn't get a risk with the vacuum.
The thickness is 4mm at the nose, 10mm in the middle and 9mm at the tail.
Rocker is approx 5cm and it has two 2mm channels.
Flex is a bit stronger than a door (like my underground stella), because i'm not really a lightweight :roll:

I fixed the fins with two steel pins on each and hope this is enough.

I would ever buy a directional, but there was only the Underground Kipuna.
But this shape is not really for light wind in the midland, so I tried my best to get a board for my weight and light wind.

The springback was about 5cm at the first layup and with the second only approx 1cm.

Flex is hard (for normal weight riders).

The blue stuff is only paint on the epoxy edge.
