No way I could carry kit on my head, not good for compression in the neck area!
We have lost our local beach due to COVID, so our other launch area's can be a real b!tch. We have slick mud banks rather than rocks but plenty of folk slip and land in a mess.
If it's a loooong way, we carry board, then rig, connect and use the wind/leverage method.
I lean back holding foil mast in right hand using my body weight as leverage (I'm 90 kg though), boom in left with the tail of the board on my thigh while trying to use the wind to loft it. It helps to have a light rig and short foil board (like the SS wizard)
