It's all about having fun...regardless. Today was hardly 10 knot, 84 kilos, 10 mt Reo and charging up wind. The dolphin boats were out in numbers. Really beautiful day.
Kami, I have noticed on KF the weight of a Zeeko Alloy is claimed to be 3.8kg and this is pretty much std area for these types of Alloy foils. You do notice the extra weight v's a Carbon foil but not enough to spend the extra dollars for many free riders.
Nice,
They rent the foils out for $50 a day in Italy, which is where I learnt - bloody cheap. 2 days was enough to confirm they are cool.
Only issue I have is postage + my location makes it real difficult to have a "big" one, I'm looking for a smaller board, normal freestyle length, 140ish and not silly wide either - so it's easier for me to have a crack - also it helps me with the "other" project I have, getting more CNC/Printing and winding experience
Olly's Union Jack painted board looked ok.
The Slingshot offerings look very nice. I would consider them, if the price is right. I believe Slingshot have partnered/absorbed MHL so they should have a fair amount of well developed product to sell.
I am a bit concerned about the combined total weight of the Hover Glider being 5.2kg. My Liquid Force weighs 3.7kg.
Weight is not an issue riding, but it's a huge issue carrying it or wrestling with it in the water.
I've been a long time stalker on Seabreeze (and I've followed this thread from when it was started), but this is my first post...
Yesterday, I received a TKF Manta (one of the boards mentioned in the original post), and I've had two sessions on it now. Since I've read this thread dozens of times I thought I would chip in with my thoughts on this foil, cover off a couple of points I've seen debated (weight, galvanic corrosion) and also mention some things I've found elsewhere that haven't been discussed on this thread, but would benefit a beginner foiler (the original focus of the thread).
Firstly, I initially went down the DIY path and built a foil. It actually went pretty well, flew straight, more than enough lift (actually a bit too much); however, it only lasted 1/2 a session before the connection points started to give way. The wings and fuselage were all strong enough, but I underestimated the force that was put on the connection points and they just didn't hold. I tried a second time to glue the everything in place (I got lazy and didn't glass them in when I should have) and the second attempt on the water led to pretty much the same outcome. The DIY project actually took me about 6-7 months (limited free time and not really knowing what I was doing) and probably cost well over $1000 (bought more supplies than I needed, bought a drill press, belt sander, clamps, etc, etc...).
Bottom line - it was an awesome learning experience, but unless you have done a decent amount of composite work and have all the gear already - probably don't expect that your first attempt will be a 100% success. Attempt 2 or 3 are probably going to be the ones that actually work... or you might just end up throwing in the towel and buy an already proven one like I did...
DIY Attempt - Looks the part and worked - just not for that long before falling apart...
As mentioned, I had only 2 sessions on the DIY version. I initially had put a 1 degree angle on the stabiliser (as I had seen recommended on a number of forums); however, that combined with my oversized, high lift box wing, it was a complete disaster... there was no porpoising, it was absolute ejection from the water at any speed. I trimmed it with washers to be very slightly negative and that let me keep the board down for the most part.
Hey Gorgo, what size kite in what winds are you talking? 10 meter is about the go for me, occasionally I put up a 14 in 8 knots or so but tend to get over powered once it hits 14 knots. Are you using Tef Gel on your parts? Bit expensive but one little tube will last a lifetime.
I am using my 7m which has always been my "go to" kite. Anything in 18knots up to 25+. I found that going out in strong winds is ***much*** easier than you would think (also we get lots of strong winds and if the wind is blowing then I am foiling). The kite rarely crashes. If it does it relaunches instantly. The small kite is easily depowered. The foil just passes through waves as though they are not there (it's awesome to come off the board, from the top of the mast, from the top of a big wave!!!). Of course, there are some get offs but overall it's much easier than light wind foiling.
I have no trouble at all going upwind. Going downwind takes some care. I either go to fast and panic, or go to fast and let the front foil out of the water. The most effective and fun downwind is to do a series of gentle carve turns and do a bit of a pumping sort of dolphin ride where I let the foil go up and down and occasionally the board touches the water. It's not very efficient but it is loads of fun and I can do 500m runs without falling off.
To seal the mast:
- clean and dry the inside of the foil. I dragged cotton wool soaked in metho through.
- insert some foam into each opening about 15-20mm down. (The foam makes a backing surface for when you inject the silicone). 15-20 mm is the maximum thickness of silicone that will cure according to the data sheet.
- inject silicone. (I used Sikaflex Marine) If it's down the screw holes then poke it down with a stick (I used a cotton bud). I also put some soapy water on the screws and screwed them in to their normal extent.
- smooth it all down with a soapy finger
- let it all cure for about a week
- I used a drill to remove any excess from the screw holes when it had cured (with a depth limiter to stop it drilling down too far)
- peel off any excess from the sides
I have been putting weak Loctite on the threads and giving the aluminium parts a wash from time to time. It's all holding up ok so far. I carry the foil fully disassembled in my car with everything in the little bags. It only takes 2-3 minutes longer to fully assemble and it makes transport, storage and maintenance so much easier.
Once I upgrade to a more performant foil, one of my prime requirements will be the ability to quickly and easily break it down and storage bags for keeping it in the car.
I have done a few sessions where I do an hour of foiling then remove the foil and install the fins and go wave riding. It's quite fun, but I think I would prefer to just have a second dedicated board for wave kiting.
I have bumped the wings on the reef once and that put a fair number of scratches on them. I'll fix them some time. To avoid that, I have moved up the coast to a more sandy bottom beach. I walk out to the last sand bar then sit in water start position with the board edged so the foil is sitting out horizontally. I then do a slow bum-drag in that position out past the bar where I can water start and ride away. Initially I was riding down, but now I go straight up onto the foil and ride away. I actually have to be careful to not cut too far upwind so that I don't run into a bommie in the middle of the bay. I start half way down the bay (between two groynes) because the sand bars angle back to the beach. If I start too far upwind I have to traverse all the bars before I can get up and riding.
I'm still using bigger kites, 14 or 10 most of the time. Used the 7m last week but had to work it to ride, which wasn't as bad as I thought it would be but was hard work.
Downwind I don't find too bad, but I'm really only riding just above lift-off speed I reckon :D
Our beach is so shallow for so far out--it's still chest-deep well over 500m from shore in some spots, so avoiding bottoming in the swells is tricky.
I've bent my fuselage; lift suddenly dies at the bottom of a swell and a couple of times I've just dive-bombed straight down to the bottom, all my weight onto the nose if the fuse its all still rideable, even with the bend so I'm not worrying about it until I can hold speed and height consistently.
Whats the board like to "surf" with? I've got a hankering for a Vanguard... Are you riding the foil strapless?
PS. If you're taking it apart every session, would you need to worry about Tefgel-ing it?
I use blue Loctite on the mast screws...
I use the straps as handles to manhandle the board into position to water start, and to hold it in place with one or the other foot.
I take off with just my toes under the front strap and the back foot on the deck pad (fairly close to the front foot). I usually wave ride in that stance on my surfboard in lighter conditions. I don't ride with my feet in both straps. I am always prepared to bail out. I have tried both straps a few times and I can see how it works but I'm not brave enough to commit to them just yet.
Riding the board without the foil I tend to get both feet into the straps for cruising along. It's quite comfy. The board is quite skatey as you would expect for something called a wave skate. The tail is wide and the fins are a bit crap so the tail slides out a bit if you load it up too much. Surprisingly the board fits very nicely into small wave faces and I have had some huge fun on it. It jumps well too.
So finished my $200 carbon foil setup, and bodged together the smallest board I thought would work.
The whole process was a bit if an experiment with filament winders, wood mandrels, hollow carbon tubes. Expanding foam and plywood.
Wingspan 40cm, chord 15cm. Great maneuverability, pivots on the spot due to larger chord. Going to make some winglets during the week, and see if they add much. Rammed the bottom a few times, and everything held which was good ! Rail shape slices through chop ok, I was able to stay up without footsteps. Feels like a faster foil, but the shape has more drag than most fast foils, meaning you have to ask for death speed, rather than it giving itself to you with wrong kite placement.
Have plans to make a production type mast and fuselage, which will shrink the width to under say 12 mm for the mast, and 15-20 width for the fuselage, although 12-15 would be do-able also.
My mate who has never foiled before had a crack, and some nice little 20-30 meter seshes, before ventilation of the main foil.
Think I can do something special with the mast, that will benefit shallow water starts too :)
