Don't hold your breath for titanium. If you're REALLY committed to leaving the mast on the fuse like I am you can bond that joint with sealant and corrosion is a non-issue. The other joints just get a fresh water rinse and some grease on the screw threads and they are fine

After some input from the brains trust.

Current Foil setup
- North Sonar HM 85cm Mast
- North Sonar 1230SF Foil
- North Sonar S215 Stabilizer
- North Sonar Carbon Fuselage 700mm

I've had this setup for over a year and a half, really like it, but my concern is that from the beginning I never felt like the GeoLock tapered interface, designed to ensure a tight mast-fuse connection was not as tight as it should be. I usually leave the system together and dissemble periodically for cleaning and maintenance. Today I noticed a hairline crack just starting to appear in the fuse in front of the insert. Also, I feel the fit is worse with more play than would be expected, and it appears that the base of the mast is touching the bottom of the fuse insert preventing the tapering from doing it's thing. I expect to be some wear, but since it was ordinary from the beginning...a bit more than one would expect.

Not try to brand bash as I'm about to order a new fuse and see if the fit is better.

Just would like to know if anyone had tolerance/mismatch issues?

What was the end result?

The carbon fuse - like all carbon fuses - sucks. Aluminum is a better fuse material. Stiffer, better fit with the carbon components it interfaces with.

i tried the carbon fuse back to back with the aluminum and the AL fuse was so much stiffer I could feel it every second of my riding.

On the Blue Planet website, Mike and his partner Stefano provide an indepth discussion of foil evolution, covering hydrodynamic efficiency, stability, and their approach on design of efficiency. While they are now collaborating with Cabrinha, it remains unclear whether their collaboration extends to detailed wing shape features such as aspect ratio, camber distribution, and leading edge profiles. It seems to focus on fuselage structure. The true benchmark will come once Cabrinha's foils are released and tested under recreational conditions, where rider feedback can validate design assumptions and highlight trade offs in lift, drag, and maneuverability.

I think its pretty clear from Cabrinha themselves that this foil does NOT have any input from Mike with regards to the actual foil itself. Solely limited to the connection.

Funny, they can say that, but we can also look at it and see that that is not entirely true, lol.

Well, most of the newer Mikes shapes released in the past few years have a very definitive "whale tail" outline. I don't see any of that in the Cabrinha shapes?

Mikeslab designed the connection system but not the wings apparently! lol what a waste. Let's get a fiat with a Ferrari designed hood latch!

I ride my garbage zetti midlength at 22 instead of the recomended 15-20. Sometimes I'll even pump up, put the bord in the water for a bit while I do everything else then top it off in case the cold cost me some pressure. Every PSI makes a world of difference. If someone could make a 30psi board it would be a game Changer - probably be a hardboard replacement for all but competition.

I feel like this conversation is going in the wrong direction @AUS126 is the problem across the speed range (hard to get on foil, back foot heavy on foil at low speed, and back foot heavy at high speed) OR does it feel fine at low speed but at a certain higher speed the nose wants to drop out? If it is the latter nothing you do involving the board will make a meaningful difference. At the most you'll be more balanced at high speed and less at low speed. It sounds to me like you are going too fast for that front wing! All these setups have an optimal speed range and if you push them too fast almost all of them tend to nosedive at a certain speed esp when pushing them with power

The way you say dive makes it sound like it's a nose diving at speed. Does it feel like you'll be up and riding and all of a sudden the nose wants to drop and you have to lay on the back foot? That's a foil/tune problem. Very common even on modern surf foils esp uni progressions

Woof! I've been a long time advocate but it
sounds like its time to jump ship!

I love my north SF foils but both will be too worn for what I want to do in the next 6 months. If north has too much corporate BS to bring a product to market before then they will have lost me.

Too rich for my blood! I'll stick to prone with my one board, two fronts and one tail!

Pushing the low end of the 680. 90kg, 2.0 ft @6 sec with 10 knots doing prone runners. The 680 is now my regular foil and the 930 is the groveler. I almost never touch the 980
