As spotted by Kami in my post on the Quatro thread, new custom 7'8 twin fin under way! First time messing with step rails and need to do more work on them plus tail shape and get the bottom rail turned but getting there!

28 3/4 wide and around 108 litres. Twin plus trailer

Yes Kovert, like the Hipster Twin from SMIK already done it, Twin fin concept thought as a SUP is a more accurate shape than other SUP shape. The Twin concept is the purpose to add static stability by enlarging the tail without losing any reliable behaviour to the Quatro or Thruster and more of that gain of static stability standing on in a waiting period or during the quick paddling strokes to take off, it's adding stability and drive while surfing with the benefit of a longer rail line and a large and powerful fin at the end of that long rail . The bonus of the Twin fins concept is that: it's giving looseness on the top of the stability of the single fin round pin. Kovert you made the right choice
Reading the PM you send to me about the CNC hasn't cut properly your file, I've got the same issue with some boards as this one had been cut in NZ that I've to convert the S3Dx into a version 8 with no editing of curves. What a shame! but your hand shaping experience will fix that as Graeme did in NZ helped by this video.
