Hi guys,

I still have to learn a lot about sailing downwind.
I've started to sail now with the hull well out of the water but I'm not sure about spin tension.

I see a lot of boats rigged like Gary's (with the spin not entirely up). This gives the spin a rounder, fuller shape, whereas mine is entirely up and is straighter in front.
I have the feeling the spin isn't pulling enough so I guess it could be the set-up. How do you know/see you need more twist, ...
