Looks like a largish guy in all that rubber. Would you know rider weight and equipment specs ? Dock starting nicely
Yes, he is "lugo" on the Gong forum, 85kg. With a Gong XXL pro wing (the old name of the "curve") and 40cm kite stab.
The Gong forum have many threads of people discussing dock starts, notably because the various French lockdowns made them able go only to inland waters.
The long "Pump board DIY" thread is also quite interesting of people just using some plywood as boards for dock starts (it avoids dinging a real board). E.g:

(brownie points for whose who get the ultra-French reference to "The Shadoks":
Wikipedia: The Shadoks were also noted for their seemingly useless and endless pumping - as the Shadok say: "Better to pump even if nothing happens than to risk something worse happening by not pumping" and "When the Shadoks pumped, nothing happened; and the more they pumped, the more nothing happened."
