Lost my fin the other day. Very slippery without one! Harness use is quite dangerous to impossible so better hook it up around the rear strap.
I was stubborn and just free armed it all the way in (about 800-1000m) total burn forearm burn out.
The nice thing is that it made me understand how the board moves, feels, when we need back foot support etc.
Often rigs break at the top of boom clamp. I have gotten in after this happen by stuffing the top section of mast into the luff pocket below the boom and lashing the mast sections together near the boom clamp with the uphaul. I was actually able to get foiling on the ride back in this way!
Not enough downhaul.
