Surfboard paradigm bending: mid point curve acceleration toeside/ rear hip on the heelside of the 66/838 asymmetrical gun

look at where the hips fall to imagine where the feet go |
The left heelside rail has slightly more area and an apex near the pressure spot around the foot.

The assymetry is subtle when it comes to area distribution, some find it hard to see the difference. |

The facet is marked for the asymmetrical #gunproject surfboard. This will be cut at a 45 degree angle with a handsaw.

This surfboard design is for a goofyfooted 45 degree stance. The pressure areas are outlined by the planshape to provide maximum curvature and control, So for the issue of having that one foot further forward than the other... the heelside rail foot is further forward and the toeside rail foot is back, the long nosed foil shape with a wide point pulled back to 50 % is trickier and more sensitive. This is ideal for the more sensitive toe side of the board. Similarly the forward foilshape used on the heelside is more forgiving.
Being able to customise for the individual via assymetry effetively opens the Pandora's box of surfboard design. For example simply matching a heel side to a toeside along a stringer squares the number of possibilities. This is without opening the Pandora's sister's box, (of twin pins and matching foils via diverging stringerlines and other amazing mathematical tricks which robots have not managed yet.)
What this means for a surfer is that each board becomes more suited to the individual. It is not just a matter of whether you are a goofyfooter or a natural footer, it's also a matter of how you stand on the surfboard. Where and how are your feet placed? Do you favour a foot? Is there an awkward spot in an otherwise smooth ride? Do you fall off occasionally, an how? The questions asked when designing a new board go beyond length, width and colour choice etc. It takes into account ones humanity and foibles. Once I realised the widening and exponential expansion of the matrix of surfboard designs within my mind, which incidentally literally felt as if all the creatures had been released, there was no looking back.
Ergodynamic design comes to assymetrical surfboards easily once one realises the possibilities.
These sound like questions not often asked in an industry full off gladitorial exploits and robot shaped mass market objects finished by girls in Asia. What would happen if humans started building boards for humans?
Guess what? Robots are firmly in the confines of the symmetry box. NAnenanenana.
The #Gunproject so far:
When we started on the #gunproject we began with the 'old faithful' model which is a design I first trialled in 1997-8. The design was based on a NACA 16 series foil and led to my understanding of displacement tails and how guns surfboards use this feature.
The next board in the series was based on the NACA 66 series. This is what I would call a pig style board but with a difference. The tail has been cut in to streamline the waterflow and leave it less disturbed.
The next design in the series is a 64A series eleven footer, which has a straight tail. This is made on the new custom blanks designed with my own rocker
