Surfing Waves

I am having trouble to find which are the MR Supertwin stock dims.
I found dims for the tuflite versions which seem a bit different, I then read some selling ads with other dims as well...
any idea?
thanks

LOL, the problem you are having is that Mark Richards is no longer making boards, a company that he contracts with does. So, the design is what you are paying for, the size depends on what size you need/want. There is no "stock dims"

For a better, idea, let us know your age, height, weight and how long you have been surfing, then someone familiar with Mark Richard twin fins can give you their recommendation.
