I’m 80kg. I’ve been using a 125L DW sup. After many terrible sessions I mostly have the hang of it when the wind is light and bumps are small. In real wind I still tip too fast.
Are the parawing boards easier to balance on? Or is the main attraction that they are smaller?
The biggest difference is the long nose of the DW board gets grabbed by the waves and wind and is constantly getting turned downwind. also when you need to make adjustments to the angle of the board a DW board will track too well vs a mid length you can just force in to the correct position.
On top of that you’ll find the PW might tangle more in the nose of a DW board.
Less tangling would be one benefit. Doesn’t happen all the time… but the first time your board rides through the bridles lines you’ll appreciate the shorter board. Haha.
I learned para on a DW SUP but it made it harder than necessary. You want a board that does not track well. Something that immediately follows the pull direction of the parawing makes everything easier. Fighting for balance on a board that is trying to go a different angle from the pull of the para is maddening in chop and swell. Midlengths generally work very well and make things easier even on sub body weight volumes. I ride a 76L (20L under bodyweight at least) that is quite narrow and 6’6" and it is much easier to start than my 112L SUP .
