I was very interested with the topic about fins choice.
To complete it, I would like to share base position in the mast track.
At the moment, I set my mast track for 6.7/6.0/5.5 at 137.5 cm from the tail on my CA 58, which is 5mm back the middle of the track. Back in time, I was at 136.5 with a 1/2 cm lower boom and had a great balance too.
I found out the most forward base and higher boom gives me a lower nose in chop with also a lower pressure on the back foot at speed.
Fins used C3 Venom V2. 36 with 6.7, 34 with 6.0 and 32 with 5.5
What do you use and how do you trim your board ?
