Had a first session with the s142 with the DW1400. According to the Sonar Guide v4 the combination should work for my - super quiet. Not a single hum
- the DW1400 went much faster and actually felt like an HA foil going upwind. Super stable and easier to rise (mind you that the DW1400 is huge and a big lifter)
- very smooth downwind and easy to pump. Was easy to pump too with s215 but this feels better (hard to find the right words)
- I needed to move my mast twice forwards to achieve the same front foot feel as I did with the s215. That was interesting. But I think that makes sense since the area on the s142 is less.. so the leverage at the rear of the fuse is less too, hence I needed to move the mast at least 1 cm forward (two times 0.5cm)
Is it more stable in turning? I'd say less. It frees up the rear more so more ease in turning. But in return I felt more feedback from the foil.
The low end .. s215 vs s142 feels the same but with s142 you reach the take off speed quicker.
Overall good. Thanks Ganeshka for sharing the impressions on the DW900. Everything you say I can relate to and imagine to be true, since the DW1400 is a bigger version of the 900. I went in hindsight too big with the DW1400 and reading your post I'm super tempted to go DW900 but my quiver would then become too full ..
In a way the DW feels like a HAv2 with a better low end thanks to the thicker profile and deep camber. It's for this reason that we need to think in smaller sizes. The more I think of this...I went too big

. But the original aim was to learn DW supfoil with the DW1400 (and my appetite for this has decreased.. looks too much hassle.. parawings on the horizon etc)
I'm next looking to test the s142 with the SF830 in wave conditions. According to the Sonar Guide this works too. I just need to make sure to find the right mast position for similar front foot pressure before making any meaningful comparisons.
