Boss, I made 'rigid' handle covers for my early Ozone wing loops. The foam core (now upgraded by Ozone) was too thin/soft to my taste. I also did not want to radically change the OD, so I just added 'stiff' for the tops tops of the handles.  The DragonFly 'removable' handles that were mentioned (I have not seen in person) appear to -perhaps be- footstrap-type overwraps. (mine are similar - except thin).

(early version pic - you can better see the top in blue)


I did something similar for the first fake boom mount. I made a plate of carbon, about ten laminations, and then cut it into strips the length of the inside of the handles if they were stretched tight. I slid the strips into tube webbing and sewed on velcro fasteners. I used them both with and without the boom. Without the boom, they were a big improvement, but with the boom was much better, both for rigidity and control in transitions. But then I switched to sections of carbon tube for the attachment, which isn't as good for stiffening the handles but are more positive in holding the boom.

I think the big problem with the larger duotones is that the canopy isn't controlled well. A solution like the converted Fone is pretty close to what I wanted to do--connect a web of cloth to the boom in a few places. That boom looks needlessly heavy. Thin-walled carbon tubing (I used light Kenalu tapered paddle shafts) would weigh a third of what that looks like from just a picture. I did one telescoping and then decided to just make wing-specific booms for the least weight. I added a ring of carbon for the clew to attach to and an outhaul for tension adjustment. Weight is a big deal with these wings.

I had a little more adventure today than I planned to have. I fiddled with electronics all morning while the wind came up and then headed to Kihei to do a wing foil downwinder. But the wind was offshore so there wasn't much along the shore. I elected to "mow ze lawn" going back and forth, Kihei Canoe Hale to McGregor point. On the first pass when I got close to McGregor the wind got really weird. The gusts were coming from behind me, toward Lanai while the steady wind was straight out toward Kahoolawe. I did my cheap-ass touchdown version of a jibe and got the heck out of there.

It's a long, long reach, but I made it all the way back to the Canoe Hale with one touch down. It's really like I'm flying over the surface. When I got back I was thirsty, so I took a break to drink some slightly skanky water that's been in a water bottle for about a month.

I went back out, popped up on the foil and ran out about halfway to the power station. Coming back I had a moment of inattention and the wing flipped. I was getting myself situated to go again while the wing did the flopping around in the wind thing. And then suddenly the jerking on my wrist leash went away and my wing sailed about 50 feet away. Nasty feeling.

I got down on the board and prone paddled as hard as I could sprint with a wide SUP board dragging a foil under it. I almost got to it when the wind got under it and it flew a few hundred feet away. While I was bracing for another sprint it picked up again and started cartwheeling away. No way to catch this thing without a paddle or a motor.

So I pointed the board for the beach and started paddling. I had plenty of time to perfect my technique--I was out perhaps half a mile. For what it's worth if you're way out on a wide SUP that leaves you with the arm span of a penguin, the best technique I found is to roll shoulder to shoulder as I stroked, reaching out further and going for a little glide. When I got about 100 yards from the beach I spotted Stephen Ross waving, and then a fire truck pulled up and a whole passel of emergency folks piled out to watch me finish the last 50 yards. Firemen, a lifeguard, and an EMT. Out beyond where I started my long-ass paddle, there was a coast guard boat doing search patterns. These folks don't mess around.

I convinced them I wasn't dying. One of the guys got on the radio and directed the jet ski, that apparently had scrambled from the Kihei boat ramp to go look for my wing. I met the ski at the ramp and he handed me my wing. It was fully deflated and the valve wasn't open. He said, "it's done for, sorry". He'd stuck it with a knife I guess. In those crazy conditions there wasn't much choice since he probably didn't know how to use the deflation valve and probably couldn't have screwed with it anyway. No big deal, I'll get it repaired. The lifeguards aren't in the equipment retrieval biz and I'm glad to get it back in any condition.

My leash didn't break, it looks like it just came untied. I reworked the way the leash attaches to the wing after hearing about Shep Nelson having the weenie little sewn-in leash fixture rip out and pop the bladder. It looks like I need to rethink that. I generally try to have critical things like leashes either be super-stout or have a backup.

It was a long paddle in, but it's good to know I can manage it. My shoulders felt great after the long haul--warm and loose. I don't recommend this as an exercise, but clearly, I need to spend some time on a prone board.

I made super lightweight carbon booms for my Duotones. Far superior to the aluminum stuff and easy to do. What I don't like about Duotone is the instability of the 5M wing. What is a minor fault with the 3 and 4M is more irritating with the 5M. It works, and it's a solid second best in my book, but the stability of the F-one is better.

The fake boom on my F-ones would be unlikely to damage anything--less than 300 grams. I've come up with a few designs for ultralight actual booms, but I'd have to take apart a strut and do a bunch of sewing to make one. As soon as I can get my new 3D printer to stop making piles of plastic instead of parts I'll print a few bits and try to get someone to do the sewing.

I went to Ka'a and then the harbor this morning and considered foil surfing, but Ka'a was empty and nasty looking, and the harbor was crowded and a little windy. It looked like fun, but I checked the wind at Kihei, saw 25mph on iWindsurf, and headed for the south side. I wanted to do a downwinder.

I got to the Canoe Hale and the wind looked pretty good. I called Bill Boyum to see when he was going to go, and it sounded like I might be able to get one run in and meet up with him and Steve Ross for a second run. So I launched. As soon as I got far enough from shore I realized the wind was a lot zippier than I'd thought. My 5M wing and 1020 Axis foil were both a bit big. I thought about going back to my truck and getting a smaller wing, but decided I was just being a sissy and I should go for it. Of course, the wind came up even more (20 gusting to 30 when I launched, 30 gusting to 40 as soon as I moved an inconvenient distance to return and rerig) and I was grossly overpowered and had too much lift. I could turn downwind and start catching bumps, but I couldn't get the wing to stop adding power even luffing it fully and holding it with just the front strap. I'd ride over a few bumps and then come off a particularly nice one, so much lift from the wave and the wind just pushing on the wing that I couldn't keep from over-foiling and crashing. With all the crashing to took me over an hour to go from the canoe hale to the Andaz--probably about 6 miles. Pretty slow. I still got some really fun rides though and learned a lot. I think if I'd had a smaller wing and the 920 foil I would have had a much easier run.

Diane picked me up at the Andaz and we had lunch at Maui Brewing. I considered heading home, but I wanted to try my 3.5M wing and 920 foil. So I went back to the Hale for some back and forth. Of course the wind dropped a bit as soon as I got out, and since I wasn't chasing bumps I really needed the bigger foil wing, but I made it work, and it was fun.

I made a fake boom that attaches to my F-One handles. Much better that those floppy things, and it makes transitions easier because I can grab the middle of the boom to do the hand switch.

Thanks, I've been trying about everything. I should settle in on a technique and just work on that. My friend Art does switchfoot foil jibes so smoothly that I can't tell what he's doing. when he explains it, it sounds very different from what I'm seeing.

There are a few people using them in Maui. The big problem I see with them is getting going. The floating bladder is a big help in many ways. Pool noodles work sort of, but not as well. The wings are fairly light, but quite a bit heavier than lightweights like the F-one. I haven't seen anything from the experiments that would make me want to get one.

Sounds like you are shredding, Bill!  How light have have you used the 920 in?  That is a great wing.

I've only used it once, so 35. At that wind speed I couldn't tell any difference in the lift, but I went faster and dropping into a wave by driving over it was more controllable.

Has any of you tried the 2.2 ?

Its very windy for the foreseeable future in Cape Town, gusts up to 44 knots right now...

It's a pretty thing. I've held one in high wind, but not in the water, just looking it over. It seemed so tiny but in the 35+ wind it had some good pull without becoming hard to control. I was tempted, but I'm certain it would just sit in my truck. At 235 I'd need a lot of wind for that, and high wind is rare in Maui.

Easy money today, 25-30mph and a little north in the wind so making way upwind was easy at Kanaha. I stayed out for about two hours on my 4.2M wing and 1020. I kept over foiling with the big 1020. Should have come in and got the 920. One day on that thing and now it's my goto. I switched to the short fuselage and I'm using the 440 stabilizer. I may actually be pumping in a manner that is visible to other people.

Or not.

So much fun chasing the waves at uppers. I do need to do a little tuning. Whenever I foil over the top of a wave I come right up on the very edge of blowing out of the water, and have to hang there on my tiptoes, pressing hard on my front leg and praying that I'm not going to faceplant.

I've got a HUGE improvement in my foiling jibe completion rate. I've gone from 1 out of 40 to 1 out of 20. Amazing. I still don't know WTF I did when I make one, but maybe that's okay. Maybe they'll just go straight to muscle memory and I'll be 1 for 1 without having any idea of what I'm doing. That would work for me.

For some reason, I was really tired when I got out of the water. Not muscle tired--fall asleep on the beach tired. No idea why. I was a danger to all around me when I drove home, so I pulled off and took a short nap. Way better than wandering across the line into oncoming cars.

I did do my highest speed ever crash today, but it was in the water, on a wave. So I got that out of the way.

My only FAST system board is in Hood River, so I was going from memory on the shaft position. The point remains that a bent shaft doesn't necessarily mean a hole in the board--the fin box generally prevents that.

I actually took one of the pushrods out of my FAST board, and it works fine. I thought it felt a little draggy with both, so I took one out and liked the feel. It's not as positive going to the side where the push/pull rod is getting pushed, but it works fine.

As I recall, the spring is in the tiller housing--effectively the same as it is with a batten. I consider this a design fault with both designs. The spring should be on the rudder so if the actuator breaks the rudder stays centered, and of course, any friction drag on the actuators would not result in a misaligned rudder, just a misaligned tiller. When I cared about this a lot more I reworked my boards that way. The return spring could (and needed to be) much lighter, and in general, it worked very well. Of course, when I REALLY cared about this I built a radio-controlled rudder and autopilot so I could have a clear deck.

Just as another opinion I am OK without the window. Once in a while I raise it over my head to glance around, but in general I have not had any problem without the window.

I suppose it could have to do with the number of people on the water in the area you are in.

Anyway, just wanted to mention that in case someone is thinking of getting the F-One Swing but is concerned it does not have a window.

I miss the window going downwind or when there are beaucoup windsurfers aiming for the same wave.

Well, hell. I kind of already knew that. Just keep going in every direction as hard as you can.

I'm also reminded that doctors and researchers work with the patients they have. The bulk of people over 50 are fat, sick, were not that bright to start with, and stopped learning anything new before they turned 30. I console myself by imagining that the number of 73-year-old wingfoilers who study new stuff 24/7 is poorly represented in studies.

And I'm going to keep pretending that that matters and solves everything.
