Funny went out to sea the other day with the boat to try some DW tow ins on the prone foil and the ocean was rough as guts ..3 days of NE wind swell mixed with SE ground swell plus some refracted bumps of the rock headlands......well couldn't stay on foil for more than 100m constantly crashing into big holes out of nowhere and ended up being as sick as a dog.I think we chose the wrong conditions.
Total disaster really , had great expectations but ended up getting our arses handed to us. Had much more success just pumping out from a point break on the prone in a NE swell and running down the beach ,or just using the ding.


Sometimes the easy bay runs are the best. I find less swell is best. That Pittwater run I've posted above is a clear stand out for FUN. Opposing bumps can cancel each other out, so you really have to be onto it. See the patterns and get in the rhythm so you don't always trust your eyes, what you see can just disappear in a second or the opposite, something huge can just appear out of no where. But that's DW'ing.

Riding in crossing swells or chop makes everything so hard!.
My biggest crashes have been on days like that when Downwinging, drop into a big one,hit a xchop and go fly :)
Sometimes it is shocking how hard you slam into the water,the speed plus the foil height plus the wave height and you really splat into the through.

To define this speeds* in a different way:

-Stall speed is where flow separation happens,you loose all lift and drop.

-Minimum sink ,just a little faster than stall.If you had 1m of mast above the surface slowing to minimum sink will give you the Longest Time possible before touching down.Could be used to wait for a chop behind you?.
Problem with anything below max L/D is drag increases very sharply so you better have some horsepower in your sleeve (wing,pump,chop) or you are toast.

-Maximum L/D or Best Glide: faster than min sink, with the same 1m of mast above surface this speed will give you the Longest Distance before touching down.I think when pumping we tend to stay at or above Max L/D as it feels lowest drag with good handling,anything below gets very hard to accelerate out of,like getting in a hole,and kind of mushy handling.
If you were towing behind a jetski this would be the speed at which you feel less pull on the rope

*All this speeds are in fact AOA's.They only are fixed speeds at a constant load on the foil.
Change the riders weight,carve a turn or add any up/down acceleration and the speeds will change...but the AOA's at which you get them remain the same for a given foil.



Yep, it is very interesting. I look at the Sink speed giving you an idea of what foil you can get away with at what speed. Obviously we don't know the numbers or have the controlled environment to properly test. Glide ratio is definitely the speed were I think you foil is most efficient, add a tiny bit of power and you what I call "PRIMED" or as some call it foil plaining. Agree, once you go below Sink and towards the theoretical stall, everything gets heavy.

Rider weight, board weight, foilsetup all affect these, but it is an existing terminology to help understand what is going on. Particularly when picking foils. Would be good if foil brands listed the actual scientific Stall, Sink and Glide speeds so we could compare and understand further.


I would really like to know the speeds too but it is a can of worms.

It would be helpful only in comparing foils before buying, but really hard to get significant data.

Even with the same brand using the same testing method you would probably end up with numbers so close together for their models/sizes that they would be confusing.

Add that the speeds will change for every rider weight, that Stab config will significantly affect best L/D and then mix in other brands :) .Mayhem.

I think towing on a calm day can get ballpark results for Vstall and VmaxL/D of your setup/weight but i have never tried it. Once you own the foil you are going to feel this speeds anyway,numbers will be irrelevant.

Thx for the DW tips, it is really hard to write about this but it helps!.

I definitely fall into the trap of going for the big rides when Downwinging,on the other hand it is fun and having the wing to keep going means no price to pay.

Sup DW is very tempting ,i have not tried it yet because i know it is going to be exhausting,humbling and frustrating beyond belief.
You guys make it look so easy, honey trap :)

That's really interesting,So you think a foil which is efficient at lower speeds is more important than one which can go fast and ride the big bumps ,so that would be a mid aspect type foil ? and connecting lots of smaller bumps is better than taking the bombs. It's interesting that you are shimming for lower speed performance as well ,I didn't expect that.So much to learn.......Great info JB.what's your favorite setup atm ?




It all depends on the ocean energy available.

On a dw run in a bay or any zone protected by the ground swell, ususally you go slower as the bumps are close together and are not fast so a super fast wing might not be not the best (except if you can keep up pumping catching bumps in front).

On an open ocean dw run with ground swell, you definetly need a fast foil, so you can go from small slow bumps to big long fast swell line.



On this run it was super windy (40nd) but no ground swell. The bumps were big and steep but not fast. Still I had to use a small wing to handle those bumps. I was using Unifoil Hyper 170 (1090 cm2).




Wow, 1090cm2 is a tiny foil! What is your weight? 40kn is very windy though and definitely helped. 21.1kmh is relatively slow average too for such a small foil. Very interesting? I am really keen to DW on my 1040HA as it is super efficient, but I fear the difficulty in getting up.

Have you got some more stats on this run.

Awesome, thanks,

Ride safe,

JB


Like I said, the bumps were big and steep but super close together, so I needed a foil that I'm super comfortable at low and hight speed (this is the one I use for surfing so I know exactly how it reacts). My top speed was 28.4 km/h which is not super fast, I guess my average speed wasn't super fast (considering the 40nd) as well because the swell was moving slow and the big bimps didn't lined up very long.
I didn't fall, didn't get out of the bumps much (only a couple times when it was too tricky). The good part with this run is it starts on nice easy bumps, so getting up on foil is no big deal even with a small foil.

The best conditions to have a good avaerage speed is when there is ground swell (but it can be harder for sure especially if it is side ways), you keep your top speed longer because the bumps are not super steep, you don't rush things up, you glide at hight speed.


I guess for this run, to have a better average speed, I would need to find the way to avoid those low speed which is hard to do with big short steep bumps. I was also enjoying the ride, doing carving turns, I wasn't racing with somebody else.

Awesome, thanks for sharing. Yep, getting rid of the lows and using the highs is the game I guess. I am just blown away you did this on a 1090cm2 foil. I really want to DW my 1040, but do not think I will be able to. It is a pump machine and so efficient, but I can't imagine trying to paddle up on it. Not coming down with lows like 15, is impressive. I am assuming the two sub readings are glitches. I know I can get this low on my 1040 in the surf and recover, so maybe!!

What is your weight if you don't mind me asking?

So much to learn, not enough runs a day to test everything .

Right now I am straining my brain over wing choices. There is no clear winner!

Keeping the glide and been smooth is key to going fast.
Here some stats from one of my last runs, nothing crazy fast and a few slow kms at the start but pretty even from about the 4km mark. I was on a 1380 foil but this same day ben was on a 1100 and he was about 10 to 15 seconds a km quicker for the condtions.

What was the conditions like ?

You also have to take into consideration speed of the swell, really different from Ocean Pacific to Atlantique.

20knots with a mixed swell, ocean run with a SE wind but East swell which kinda ruins the bigger bumps as it cuts them up a bit.
I think Ben averaged 26km for this day which for us on the Goldy is pretty good as conditions are never lined up and perfect.

26km is a very good average speed for sure ! Usually 26km/h is pretty much my max speed....

I plan on going to south of France Mediterranean where the dw is amazing, Titouan Galea said it is one of best place in the world for dw foiling. We will see if can get a good average speed run there.

186 bpm - That's a little scary, be careful up in that neck of the woods old man .

Nice run. We always seem to get swell 90+ degrees to the wind which is cross on to begin with, makes it hard. Had two cracking bay runs that were too much fun, I will post up soon some stats.

26kmh is smoking as an average - WOW!!

I am ideally aiming to try get my runs keeping my HR under 140 (which is really hard). The ocean just calls for more!

Had 2 awesome runs over the weekend. Both bay runs in offshore winds. Wing-Surfed up to Flint & Steel Reef/Beach, packed down my wing into my backpack, then DW foiled back out of the bay out to sea and around Barrenjoey Headland. Zero swell as it was all offshore, so just short fetch wind chop! Lots of fun, big foils - 2140HA.

Long videos if you can be bothered (edited down a little, but a decent amount of the run) and also the stats at the bottom.

Conditions, Run 1 - WNW 18-25kn. Run 2 - WSW 20-25kn+.

Riding - Naish Hover 125 with JET 2140HA/310HA on 64cm Fuselage. C100/85cm mast. 3 degree shim on plate mount, no rear wing shim.

Run 1.



Run 2.


Stats,

My Wing-Surf upwind on the Naish Wing-Surfer 3.6m. (Only recorded one run as wanted to save battery on the watch).


Run 1.

The thing is prone guys think they can use their small wings, just like they always do, but it doesn't work this way. You have to go step by step (which means bigger foil). It can be frustrating but rewarding at the end.

Yes, definitely. the hardest but also most rewarding form of foiling bar none! Worth every crap run. It's easy to get discouraged at the beginning, but if you soldier on through it you are in for a treat!! SOO GOODD!!

Yes, big board and big wing. No need to make it harder than it needs to be. Even on big gear, you're getting excellent turns and riding for as long as your fitness will let you. 5km waves are now easy, no crowds, just 100% glide and fun!

So riding for as long as your fitness will let......Max heart rate 220 - Age . For me 220 - 58yrs = 162bpm max
Jacko 220-40? = 180bpm max and average 160 , That sounds like a lot harder work than I would have thought !
But I guess it depends on conditions a bit too.

Yeah everyone's a bit different on the heart rate scale so would not go of the 220 - Age, I am 45 and still have a max heart rate of 193.

If the wind is good and I just want to surf the whole way my heart rate will stay in about the same zone as when I walk or maybe slow jog, if I want to push for speed then you can max out as many times as you want trying to run over bumps and hold your top speed for as long as possible.

The readings on my stats above for the heart rate would not be right as I had no heart rate strap on and that was just taken from the watch which is never accurate.

When you learn for sure its a lung buster but once you get it you can really do it as easy or as hard as you like.

The more you get better, the more it is easy and no cardio at all, except as Jako said when you want to go really fast all the time.

So riding for as long as your fitness will let......Max heart rate 220 - Age . For me 220 - 58yrs = 162bpm max
Jacko 220-40? = 180bpm max and average 160 , That sounds like a lot harder work than I would have thought !
But I guess it depends on conditions a bit too.



The more you get better, the more it is easy and no cardio at all, except as Jako said when you want to go really fast all the time.


100%, I am definitely noticing a huge difference the more I go. Yesterday we did a light bay run (well 15-20kn, but that's light with only 1-2km of fetch, so small bumps), and I had to work pretty hard a lot of the way, but then again, am also very comfortable running super slow and conserving energy and try to only pump when I need to. There was plenty of flat spots, so you have no choice there, but on the bumps I was riding as slow as 12 kmh at times. My HR average was 138bpm including 4 drops (it was super hard at the beginning) and a max of 170bpm.

I was also trying something different by using an 80cm fuselage. I usually use the 64cm STD fuse, but wanted to see the difference in pump power and stability. I was expecting limitations on turning and pumping, but these were not so bad and the gains on power were substantial. Totally changed the pump frequency and output produced for a given power. Not sure of my conclusion yet, but definitely going to give it another go. I'd like to do a better run to get more data.

Here's a snipet of the run.









Interesting stuff. This fuse puts my front wing 8cm further forward and my rear wing 8cm further back. I am thinking I will be able to run a smaller rear wing with this fuselage, reducing drag and increasing efficiency.

All about working less and getting more :)

Ride safe,

JB

20knots with a mixed swell, ocean run with a SE wind but East swell which kinda ruins the bigger bumps as it cuts them up a bit.
I think Ben averaged 26km for this day which for us on the Goldy is pretty good as conditions are never lined up and perfect.



26km is a very good average speed for sure ! Usually 26km/h is pretty much my max speed....

I plan on going to south of France Mediterranean where the dw is amazing, Titouan Galea said it is one of best place in the world for dw foiling. We will see if can get a good average speed run there.


Yeah etang de berre on a good mistral must be so good. He said you would be able to do a pop up on a prone board there that's how steep and big the bumps get!

Sup foil dw racing has nothing to do with "free dw", especially is this light conditions, the best guys (young guys, not me...) hammered chasing front bumps.

Nice Frenchfoiler! Looks like you got up on foil just as fast as any of the other guys in that race. Cool to see several of your boards in the race too.

Any particular reason you were on a Takuma for that race? Which front wing? The Kujira 1210?

So you are the shaper of the 52foilco boards?
I was checking them online a few days ago,they look really good.

Nice, looks like the first day was better than the 2nd day from the vids I have seen.

I love the set up with the boat rides straight out into the wind!!
