I'm new to this foil caper and just had a couple of great days, my first flights (SUP foil) and long fast rides, starting to get some control of the climb and a few fast turns. The stoke is real and the wind has well and truly blown my hair back

.
The dopamine high came crashing down when I got caught inside this morning and got rolled by numerous over head whitewater sets, nothing I'm not used to and I wasnt too concerned, nice deep water and no turtles here, but I came up with a bent alimimum mast and twisted base plate. A $300 lesson for me to avoid getting caught inside - and stick to smaller days... maybe

I've done a bit of forum post searching and now understand the foolishness of letting the foil go through the washing machine. But I'm still wondering how to handle whitewater best..... to protect the gear, and myself.... beacause it will inevitably happen again....
If you're off the board and about to get cleaned up, should you push the board behind you, and let the white water hit it square in the tail? or maybe tip it upside down, foil sticking up in the air? Any other techniques (other than buying a carbon mast)?
Also I read something about paddling over large whitewater being bad, the foam lifting the board exerting significant pressure, basically separating the board from the foil, again busting masts/baseplates/board tracks. So how do you get over large white water - bury the nose and jump? Spin around and ride it like a man?
Thanks in advance
