Carl,

It is designed to be sailed in both Uni and sloop configurations both with a kite.

The photo is actually of the Blade F16.
The Blade 14 will look pretty much the same.

The 16 carries heavy crew weights very well.
I've sailed two up with 180kg on it and unlike other boats of its size you just wouldn't know you had that kind of weight onboard. Sails like it does one up.

I'll do the plans for a 14 ft version once I've finished drawing the plans for the F16.

The platform in the photo is simply made from 4mm ply as will the Blade F14.

It will be bulilt in glass but I will keep the home build option available.

Sorry I can't give you the hull width. I have it detailed at home in the preliminary design but as I'm also working on another design for very young kids I just can't keep all the numbers in my head. The Blade 12 will be a Uni no kite.
Good luck with your design.
I would really like to see some more photos as things progress.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
