It's called the Slingshot one lock!

No tools needed, no more corrosion, stripped out screws, or pesky sand in the grease (I somehow drop at least one greased bolt per front wing change)

Also new stiffer masts and wings on the menu .

Talking to a local team rider. He is not sure if windsurf foil is supported with new system...
Anyone know?

That would be a bummer, but not surprising. I really like my current Axis kit, but I would consider the new Slingshot kit if windfoil was supported. If Slingshot wasn't so slow getting the Phantasm stuff out, I'd probably still be riding Slingshot.

The best selling front wings will be available first, which is the current PTM and E series. The infinity low aspect wings are not.

Not totally screwless. The pedestal appears to still mount using screws and T nuts. Correct or am I missing something?

The foil system is completely screwless from a front wing, rear wing, mast connection point of view.

The foil mounting to the board, slingshot have what they call the RTS system which has 2 front sleds that you bolt into the track and stay there, the foil hooks onto the sleds and then you use T bolts to secure the rear of the pedal stool.

It's a faster system than bolting down 4 independent track nuts and bolts and lining up the pedal stool on the track markers.

Bit of a solution looking for a problem for mine.

What are we talking, saving a few mins over a couple of hour session?

I'd use it, just wouldn't pay extra and wouldn't base a purchasing decision on it alone.

Downgrading from M8 to M6 in the process for the pedestal bolts? I strictly wind foil for now (phantasm w103 mast) and wonder about the forces and stresses involved. Also, isn't stepping down to M6 pedestal bolts counter intuitive as well for those wingers progressing to jumping and other acrobatics? I'm not very advanced yet, so I'm looking for insight.

The pedestal bolts in that configuration with the t nut on top(instead of the flat head screw) is probably fine with an M6. I broke the pedastal bolt on the hoverglide system using the flat head screws. The broachimg for the hex key was too deep leaving a very thin section where the base of the tapered head connects at the screw shank. The head of the screw popped off of the shank. The threaded section was fine. I just replaced the stainless steel with stronger coated steel screws.
I'm in fresh water, so no issue with corrosion.

The tracks in the board break well before the screws. Using a longer t-nut does a much better job strengthening system than choosing m8 over m6.
The new system should be much stronger than the old system, perhaps allowing the use of front wings over 1m span

The RTS system looks to be very strong and yes it allows for bigger front wings (which are coming in the PTM line).

one area of really large front wings is the stress on the fuselage and getting carbon right is complex. The one lock will allow bigger front wings a d cope with the stress that comes with it. .

I was thinking about sand being an issue but this video puts that to bed as well

A friend from MACkite boardsports is out at AWSI. He said it will be for windsurf foil too.

I like the idea behind the system. That locking system looks like it borrowed some ideas from the 1990s style quick release windsurf boom heads. Can't remember the company that made them. It essentially uses the same cable system you find on ski boots.

My first question would be: can you replace the cable? On the windsurf boom head clamps you had to had to regularly replace the cables because they wore out and eventually snapped off.

Yes. Uses Dyneema cord secured by a pin held by FCS grub screw. Will come with 2 to start. He says they started with brake cable steel but getting the crimp in the right place was problematic.
In theory even as the foil tail and wing fuse parts wear you just adjust the length of the cord and it pulls the taper together. Just gets slightly shorter.
Going to be interesting to see how much.

Not necessarily - If M6 can bend in a boom front end when its just running through plastic, I think its too thin for foil mast connection.

Anyway I will reserve judgment and wait til they've all had a couple of seasons use - but for now my preliminary thought is I think the joint will wear too much and I will have a lot of work to do tightening them again for customers. Like the GoFoil front wing onto fuse that gets loose. Interference fit is not a good idea for composites and when you add sand and salt it makes a wonderful grinding paste. Just look at the wet black goo that develops in your windsurf mast (that the sail rigs on) after one session.

The front wing section and tail section is joined with a chamfered joint, as wear happens the joint moves closer together, effectively shortening the fuselage slightly, but also expanding the joint into the mast socket. The dyneema loop is adjustable so is shortened to take up any slack.

Yes that taper can wear and it doesn't matter (quite ingenious really) ..
but the square fuse thru a square hole in the mast can wear and will develop slop - unless the wear rate of the taper flats is less so the expansion is faster than the mast socket wear.. Nup
IMHO

It's a triangular section, not square so all slop is taken, quite ingenious really. I've ridden it and it works well.

Indeed. I'd say a move to m6 is an unecessary move backwards. But if two m6 bolts can hold a race foil in a deep tuttle foil box (generally speaking) then should be ok with four holding a pedestal?

4 x m6 bolts holding the pedestal is the system used by almost everyone in the industry except slingshot phantasm. Heck, even Slingshot's new flag bolt system is m6 (x25, which too short for carbon phantasm masts).

Yep, should be all good, but why move from m8 to m6? There is no good reason.

Hopefully this link below works, as others have said...

1. triangle shaped, wear on the parts means it will still "cinch up"
2. Both Carbon and aluminum mast is all one piece (no more sloppy play from mast and separate mast plate)
3. RTS system for stronger and quicker foil installation/taking off.
4. Even if one lock becomes "unlocked" it's virtually impossible to pull the tail and front wing out, you have to follow a wiggle and
push process to release the front and rear wings.

Just from personal use with the phantasm, I swap foil wings out a lot, pretty much every session as I like to be dialed in on that given day.

I use 4 front wings and 3 rear wings in my daily quiver. Every time I take a bolt out, there is grease, I end up dropping a bolt and either lose it completely or the sand is stuck to the grease which as we all know you cannot screw the bolt back in, so now you have to find a rag and re-apply.

Aluminum fuses and carbon masts can produce corrosion, the bolts securing mast foot to fuse get worn, bolt heads get stripped out or can loosen up on you.

When you get into front wings over 100cm in width and/or wide chord and bigger surface areas, it is putting amazing amounts of stress on the fuse as well.

Actually there is a good reason, 4 x M6 screws are more than strong enough for mast mounting, many brands have been using it for years, never heard of a bolt failure. Smaller screws allow for more "meat" to be left in the mast plate, the slots are narrower which results in a stronger, lighter joint.

Every foil I have seen for the last few years is using M8 bolts to the tracks.
you folks do realise it refers to the bolt diameter not the tool size used...
Show me all the systems with M6 ..

Actually my two biggest gripes with the foils systems on the market at the moment are compatibility and complexity.

Nothing seems to be compatible between brands which would be fine if there was any consistency in their product lines. Brands seem to routinely change connection system between wings / fuse and mast and as soon as the new system is out replacement parts for the previous generation become nearly impossible to get hold off.

Add to that an insane range of wings / fuses and mast options most brands have on offer and it feels like they should focus more on durability and functionality. Just look at the Axis foil range. There are so many different options that most parts are special order only.

I get that at the top end in racing people want the latest and greatest but realistically how many people are in the market to replace their race foils every year.
