you got me Tardy, Tardy you win a video , I hope you understand my english but you can only watch it if you don't. I caught this timing to show off my last design what I'm cooking on my computer during those winter time here in Northern hemisphere.
About this tail , didn't think specially about tube riding those wings are more for carving and manoeuvre on the face, in fact i really work on the rail line because I usually find barrel on my backand so I need some good rail from the nose of the board which is quiet difficult to blend from a SUP thickness even with a zero flotation like this 88 liters for 80 kg.
Here a another sketch with a better adjusted rocker which might allow to hold high line like Slatz is dealing with while he is making the end section of is local reef break. SUP got thick rail it can be hard to stay high...
I put all my knowledge tweaking geometrics to blend the faster sweet spot till getting bite from the front rail to the front fin.
