Beeline,
Not sure if it is a "fix"..but it sure is an observaton/opinion.
Peter did initiate the 'fin-forward' design. It is so unusual to hear people talk about 'fin-forward' stuff, because I have never known anything different. The trailing edge of our slab single fins hovered around the 17" mark..just as it does on our thrusters today..albeit the rail fins though instead of the centre.
The slab design however was dependent on really straight bottom and deck lines for speed because as all 'single fin principle' boards, the performance came from the shape..and not the fin(s).
Enter of course Simon Ando and we all saw what happened when we experimented with multi-fin arrangements.
Perhaps most pertainent to your question however is a guy called Greg Webber and how he reintroduced the concave, showed us what you can and can't do with curve (bottom, deck and outline) and combined it with a thruster fin set-up and boom!
I don't believe any other shaper came close to Webber in the early 90's..everyone was watching what he shaped and what his boards were doing in the water. Webber generated speed and drive with curve..quite the opposite of 70's thinking about straight rockers and planshapes.
Now, a decade later, we have lessened rockers and concaves..but the lessons learnt are still with us. You can have length with manoeuvreability if you have curve..and concave..and 3 fins.
Slabs however, were left behind cause they were too straight to go long.
Personally, I have never liked thick, chunky kneeboards. They don't enter and the surfer always seems to sit on top of the water.
Additionally, I am a kind of big guy..certainly not small and spindley.
I don't wear flippers and have always been very aware of paddle-entry and bottoms that get to planing speed very quickly.
I took what Webber showed the surfing world and combined it with a touch of Simon Anderson and heaps of Crawford. In 1994 I booked advertising space in "Waves Magazine Buyers' Guide" and used a pic of one of my personal boards..it was 6'2" long x 23 1/2" wide.
I knew that David Parkes, Wayne Hutch (Kneeon) and Peter Daniel (Division) would also have kneeboards pictured and I intentionally wanted something published that would show something totally different to the other shapers involved.
From memory, no other kneeboard pictured was longer than 5' 8".
If nothing else, kneeboarders were shown that you can go longer if you choose..and my first ever order to the US some 4 years later had the guy post me a pic of that board out of the mag (thanks George!).
So the advert..and the board, worked
hart.
PS
Sorry for the long post
