Look beery, it's simple, I got the award last year, and so every chance I've written something to require that comment ... don't sweat it, rather, give us your thoughts on the fin plan for the franken thingy ma board ...
Like to hear JD's thoughts too ...
JD, paging JD, ... you're wanted back in your thread (before the 'tard takes over )
I usually wait til' i've got new pics before I respond, but I dislocated my shoulder again on Friday, out surfing - my secoond lil' trip n an ambulance, so I've slowed down on the work front...but not for long!
I actually buy into Beery's attitude to twin-fins. Prettymuch everything fin-wise is a variant on either a single or a twin. When you move quad rear fins up closer to the front pair, you get progressively twin-fin-like characteristics. If you move them back and closer to the centre-line you get more thruster-like.
And then with thrusters clustered close, you get single-fin-ish.
With Matty's board, the front pair is further back than for a thruster, and the fins will be larger than standard. Literally as if to save on the tedium of excessive numbers of plugs that quad/fives mean.
Also the flex of those big swallow sides - keep it clear from the obstruction of a quad rear pair.
I'm enjoying mine, purely twin-fin, but despite the long straight rail line through the tail, I get some of what aeronautics calls "Yaw" - that'd be like having the rudder in an aeroplane too far up - the plane will face diagonally to the direction it's flying, with nothing pinning the tail to follow the nose.
This is the drifty feel twins are both notorious and well-loved for. I once loved that feel, but as a big guy and not getting younger, I like less of that. I think of my board, the Baumgartner some way back in the thread, as a "Dual-single".
The stabiliser on the Frankenboard would be for giving just a little of the central directive influence of a tail fin behind the back foot. This is what I also did with Dolf's Gizmo - his initial reports were a bit of a worry - though he stated it was blindingly fast, it was'nt giving him the joy in the looseness dept, so and I've decided Matt's will have less of the Tomo no-toe-in or cant story. Dolf tells me the Gizmo has grown on him with some more conventional sized fins.
