Just recently i tried my brm’s again with my small wingboard.
I am 68kg, ak phazer 5’1x23x55l, progression 140, mediterranean 1.2m windswell… onshore wind with a slight tilt to the left.
First day, lit with the 4.2 wing, not sure about windstrength, probably 20-25kn. Tried 4m parawing, got up no problem, but was well overpowered, so a bit of a handfull…therefore tried the 2.9m also, but too small…
Next day, a bit less wind, not sure about the windstrength, maybe 15-18kn… i could get up relatively easily with my 4.2 wing with some push of the waves, certainly wing was not lit, but no need to totally go for it to get on foil. Then tried the 4m brm, couldn’t get up, no chance…tried the 5m, still did not work, some near misses, but then the chop would slow me down everytime.
Switched back to my 4.2m wing, still worked well.
I guess with better direction to use the push of the swell with the parawing i would have gotten up with the 5m no problem. Interestingly with the wing, the usable wind window angles when pumping seem a bit wider than with the parawing, going out on my good side/regular and port tack/with the wind from the left, i could bear off enough with the wing to use the push of the onshore waves no problem, where as with the parawing, i couldn’t do that as much without loosing too much power. On starboard tack going goofy my pumping technique is less effective, negating the little advantage of the better angle… and also i had less leeway, so got up in that direction once or twice but wasn’t easy, more out of sheer luck than my doing.
In a nutshell, i suppose with a slightly bigger/longer/narrower board i would have made it no problem. Not sure where the sweetspot lays for a one board wing/parawing quiver, as i do not want to go much bigger/more volume winging. I am hoping that something like 5’6x21x60l could do the trick, will have to try my old 5’3x24x66l phazer for comparison…will see…
And answering your question regarding pw with a small prone board, i don’t really see that happening much in the near future unless for very specific conditions like maybe the gorge or maybe next gen parawings with wayy more depower.
