Formula Windsurfing 3 - Selfmade Mast Mount

First Impressions from my Selfmade Mast Mount, paired with a GoPro Hero 3+ Silver.
A beautiful Formula Windsurfing day on my home-lake, the Möhnesee combined with sunshine and stable West winds is always worth hitting the water.
I used a Lorch Formula board along with a 8,6 Gaastra (GA) Vapor and a Hurricane FRB-1 on that day.
For anyone intersted, I went up to 24,90 kts topspeed in these shots...
