Regarding the rake, Armstrong recommend to put the mast 2 cm further back.
what's your opinion about it? mine still in the box due to a back pain.

I like that the new mast position is supposedly back a bit in the track relative to the previous versions. I currently run all of my foils slammed forward on my KT board and nearly all the way forward on my even on my Army 5.11 SUP. Potentially getting a little more front foot pressure is welcome especially on the KT. Curious to hear from those who have the new mast too.

Any over 100 kg riding the new mast ? Specifically the 795 one ? I'm interested in the torsional stiffness and pump ability when you put a big board and a big bag of potatoes on it. I currently ride a 75cm Cedrus mast on the SAB 1350 and while it handles pretty well, i do understand that stiffer is better for big spans

I'm 100kg with all my gear, and just switched from the A+ 72cm to the new 935 and using the 99l FG board. Using the 1550v2 and 195/232 tail.

The A+ mast felt wobbly in any type of chop or rough water in comparison to the 935 mast. I can't really remember what pumping was like on the old mast, but everything on the new mast feels better and more solid... the foil and mast feel like one unit now. The new mast rake also puts the board slightly nose-up and seems to deflect off the water better when i screw up in waves.

Thanks kiwi , that sounds really promising , specially at that length.

Man so wish I could get a prone in - WA in summer I tell ya!! I can just tell from winging (even yesterday on the wind created runners) the pumping prowess is markedly improved. Even from the 72 A plus mast and that's on a fat ass 1250. Can't imagine on the HA. 2cm back . tried it - went 1cm back and yesterday had it in the original position. They all felt fine to me. In the original maybe a tad back would have been better. But those above using the HA would notice it more. May have to man up and whack my sons 725 on today.

Per MAF recommendation I moved it 1.5cm further back and it worked great with 725. I noticed an improvement in pitch stability.

Mate of mine got his first prone in - from the A plus 72 mast. I asked him what was better. He said "everything by about 200 percent. Stall speed recovery, glide, turning angle and speed, pumping especially and the resulting overall angle of attack allowable up and down the wave face. " And again that was on a numpty 1250 with that wobbly wonky V tail (can't stand it myself that tail but some love it).

Stall speed recovery is better...do you think because of change in mast angle or just more control being stiffer,I just had a session on the 1125/85/50 and I love the pump and efficiency of that wing but it can be tricky sometimes,be keen to hear from someone who prones that with the new mast.

I'd be curious why they need to be pushed back in the box because of the rake, in my mind you'd need to push them forward to compensate unless the mast bottom pushes the wing forward?

I guess as the foil will end up with the same angle of attack the board sails nise up. Therefore if you feet are in the s same positions your centre of weight will be futher back.

Just had my first prone session on the 795 Mast with 925/50F/195(blueshim). Started at setting 4, then moved up to 5. Probably could have gone to 5.5 or 6. (4'5 FG board).

Waves were waist high and clean. I'm an average prone foiler...would be better if I didn't wing all the dang time haha! What I immediately noticed was the difference was more noticeable than winging with the new mast. It just feels like a completely different rig. The reduction in drag surrounding the mast just frees up everything a bunch. The V1 mast's drag created a sort of stability(drag factor) that just isn't present with the new mast, so movement in all axis feels more free, and a bit challenging with 50 fuse after first few waves, but I was getting 2-1s no problem.

I was able to basically stall out the pump on the way back out, touching down, then get it back up to speed (dealing with poor mast placement at first). On the 72 mast, as soon as I got low or slowed near stalling speed, there was no way I could get it back up and moving with the 925. It was only an hour session and the majority of time was wasted on poor mast placement, but I can tell you this mast shakes everything up and will require a bit of dialing in compared to your current setup.

I usually ride v1 around 6, so prone on the 795 will be at 5.5 next time, FYI.

MAF: slightly off topic but wondering why you opt for the blue shim with that setup. I have the same setup (but with the 935). Thanks!

I typically like a bit of lift from the tail to give some opposing feedback to the front wing, which adds drag, but keeps it a bit more stable at speed. I change it up a bunch, and my buddy just told me he was riding his with two red shims prone, so it's kinda guessing for me at this point with the new mast.

Just had a wing session in flat water to try and push the HA726/935 Mast a bit. Started with blue shim, 60 fuse and mast at 5.5 on the 60L. Could have moved forward a bit (mental note). Hit a personal best of 22.4mph pretty easily with my 5M OR Glide. Then I went and took out the blue shim and my max speed dropped to 20.4 on the same stretch. The drag on my arms was noticeably increased as well, but the stability was also increased. I went in and added two red shims and moved mast way forward, but the wind died - curious how that reduction in drag would have felt. Again this mast is accentuating changes to the rig as there is less 'noise' coming from the mast. Pretty mind blowing.

Thanks a lot! My area has been super windy this week (25kts+) so am trying to dial in the 935 with my 34L for winging. For speed winging, albeit at my limited skill level, I've really been digging pairing the 60 fuse and 195 with one red shim with either the 725 or 925 on my 60L FG--8 on the mast track. I've been able to push my 82kgs with a 4.5 Strike V2 to about 33km/h with the 925 and 38km/h with the 725! I'm capable of hitting considerably faster speeds with the new mast. Totally agree--pretty mind blowing.

How you guys finding the "stability" of these Ha wings with the new mast ? Improved. ? You know what I mean - is their less unpredictable weirdness. ?

So much more stable, at least for me. I used to not like the 50 fuse on the 85 mast-it was too sensitive for me. The whole rig now feels like a solid unit so controlling the 50 has been super intuitive. And the 60 is just rock solid, even with my two HAs. I only use the 195 tail but all this improvement in control and direct responsiveness makes me want to give the V another go.

I can't decide which mast to get attached to I have both 935 and 795 but I don't know which one to choose! the shortest seemed very direct to me. HA use in choppy seas

Transitions were a bit more technical, so keep that in mind.

More technical in which way? Less stable due to +1 set up? Any of you on the 935 still wishing it was an 85cm or that you'd gone to a 795 for winging? A few of us locally have ordered the new masts (2 x 935cm and 1 x 795) and should have them soon. All of us have been very torn on the sizing.

Well I've already been out in some real peak to trough head high ocean swells in 20-25 knots and I didn't find the 795 a problem at all. That being said more is always better and would rather be on the 935 but at 2k a pop I will make it work. I've already adjusted and the shorter mast length isn't even a concern now. It's become the new normal. Given the good power even just off the water you can ride it much lower.

also Had 4-5 few crappy (WA in summer flat water skill sessions Perth metro in summer ) and found it very intuitive to use. The lift is very even and fluid around tacks, gybes etc -

Next, a report on my experience with the 935 after 4 sessions.

Session one (935 with HA725, HA195, 5.2 wing in 15'ish knots of wind with head high to slight overhead surf): Everything was better. More stable to foil, exponentially more glide (made the 725 glide like the 925 did with my prior mast), foot pressure more stage (1.5 cm further back than with V1 85cm), faster 39km/h peak speed dropping in. I also found it more stable through white wash after wave passed by and more stable overall while riding. Great session

Sessions 2-4 (935 with HA525, HA195, 3.6 and 4.6 in 20-30 knots of wind with 6-10 foot surf): Still big improvements in glide (525 glides like the 725 did with prior mast), stability to get on foil and recovery when a tip breached I was able to stay on foil where I definitely would have dropped like a stone before, also handled white water a little better.

In all sessions, like others wrote, the mast felt really fast and didn't seem to slow down even when the foil was buried deeper.

What I'm not sure about... I'm finding the extra length has definitely impacted my wave riding. That said, I want to be clear about how I see this. This is a physics problem that can clearly be resolved by a physical conditioning and talent based solution. What I mean is that there were points where I was able to ride a wave like I had before but it was definitely more demanding of my legs and ankles and required adjustment to technique that I definitely don't have wired yet. I'm finding my legs are more tired after sessions which suggests to me that my physical conditioning will adjust to the new mast. I'm 75kg, so I'm guessing this will be less of a factor for bigger or more powerful riders. There are two guys at my local spot who ride 95cm masts and are visual proof that my problem is not about the gear, but rather my ability to manage it.

I still think this is an exceptional upgrade. Based on my experience, body weight might play a factor for choosing a mast size especially if you're getting into surf and want to crank turns. Over the last few days we've been contending with chest high chop in-between waves so the extra length was very helpful at times. Also dropping in on the bigger waves it surely helped. I could see also owning a 795 and riding it when swell is smaller and/or in lighter winds or places where chop is less of an issue.

Lastly, I need to do some more experimenting, but I think I might like the 725 better than the 525 with the 935. Also, I have a MA800 coming soon so I'll report on what that's all about.

Anyone try this with the HA 1525? Seems like that wing was held back by the older masts flexi nature.
