Foil Math Wave Size = 2X + 1 and Big Waves
« on: January 30, 2023, 02:22:48 PM »
When foiling the size is multiplied by 2X +1.  This is what makes foiling so exciting.

A 2 Foot day feels like 5 Feet

A 5 Foot day feels like 11 Feet . . . . 

 
During the latest “Eddie Swell” the buoys rose up to 11 feet @ 18 seconds.  Mavericks was crowded with 50+ people.  So Jeff Clark called and said “Let’s go tow foil!” 
I would love to tow in or around the reef at Mavericks but Jeff is pretty staunch about his opposition to wakes when people are paddle surfing.  So we went a bit further North. 

I said “No need to go deep, there is plenty of stuff to catch flying wide.”   And here is where he put me.

think of how much weight you could have gotten rid of with a small tow board/foil setup though.

Bigger surf = smaller crowds. Always, no matter what the gear is.
Foote 10'4X34", SIC 17.5 V1 hollow and an EPS one in Hood River. Foote 9'0" x 31", L41 8'8", 18' Speedboard, etc. etc.

Sick!
I like the equation.
Jet skis are noisy and stinky (gas fumes).  An all electric jet ski always seemed like the obvious answer, and finally became a reality in 2022.

Rad.  The foil math may also involve adding some exponent for injury potential.  With more size comes remarkably more speed, and the wipeouts start to hurt, even just hitting the water, but worse if the board or foil is involved.  Whiplash and concussions from the bucket effect, ribs, charley horses, joints...damn it sucks to be in your 50s.  My last bigger day out, I think I peered over the edge for as far as I want to go, the point where the fear of injury overtakes the rush.  Which is another way of saying when I got scared.  ::)

I agree a smaller board and foil would make it more fun! But also agree it comes with cost, especially if you haven't practiced the gear. That's the training element for big wave chargers...you have to actually use that gear when it's not huge, so you aren't learning the gear in a critical situation.  That's particularly a problem for people who don't tow much, as the water start can be a challenge on a small board without straps...so maybe better you go with what you know. 

Finally, I am mind surfing these waves on my efoil.  That's been blowing my mind lately, getting into larger stuff super early, "letting go of the rope" (turning off power) and gliding for SO long, then kicking out way before it's even breaking.  It's allowing for chasing waves that are otherwise impossible without a tow team.  It would be nice to do so without an 80lb craft, but work with what you have.  My last session I experimented with a small front wing but a comparatively larger stab, to get faster speeds but with added stabilty/control...seemed to work pretty good.

Impressive. Would love to be able to tow into some waves with my small wakefoil board, but that's looking pretty insane size for mere mortals!! Can't believe I'll ever think yeah I want do that! Great thing about foiling is how fun small waves are. If anything your math is too conservative.

Wait 'til you hit 76. I'm amazed at how things that I used to bounce back from instantly hurt so much longer. I got a mild concussion from a fall a month ago and my arm went numb (yeah, it was fairly violent). I felt like shit for two days. If it had gone on a little longer I would have visited the ER, but I felt fine by the third morning. I mentioned it to a friend who is a retired doctor. He chewed me out, gave me a quick parking lot physical, and finally pronounced me OK.

He said concussions past 60 are potentially a lot worse. Less flex everywhere. A lot easier to break one of those hoses in your head and wake up dead.

Blooper Shots.

Since I am barely an 'old guy' I managed to shake this one off pretty quickly. 

1) I was towing and hit some kelp.  But I seemed to recover.  Then when I was dropping I got the speed wobbles.  See the kelp on the Wing Tip.

2) Then I went flying
