Does anyone have knowledge or experience in drilling the 2022 H series Cabrinha front wing to fit the 2023 hollow carbon Cabrinha mast?
Its not needed. I tried my MKI frontwing on the new mast with the 2 bolts and it works fine. Besides that, the screws are only there to secure it, the construction is taking almost all the load.
Although the new mast is noticeable stiffer as the MKI, it is for my 97kg still a bit too flexible so I stay with my Cedrus.
I wrote (In Dutch, but DeepL or Google translate work okay) an review about the 1050 with the new mast, compared with the MKI.www.facebook.com/groups/wingsurfnederland/permalink/1449476722520906/

New '23 mast has a removable brass barrel nut, you can use all three screws with the '22 foils

Please take my disagreement without offence. Your statement is exactly why the cross bolt perpendicular and in between the other two bolts is needed. The mast is noticeably stiffer and yet the foil underneath appears to be flexible in your own words. The leverage on the mast fuselage joint is massive when under load. Yes the two bolts will work fine...to a point. However, when that 'point' is reached the joint will flex open incrementally and 'flex'. The cross bolt would come into play at this moment, inhibiting further flex and 'opening' of the joint. I hope this makes sense without causing insult.
I think people shouldn't be offended when they don,t agree on some points 
, but I think the cross bolt is more a gimmick as really making a lot of difference.I tried the new mast with both MK2 1050 from the demo and my own MK1 1000 (with just 2 bolts). Personally I felt no difference in flex between them. Biggest gripe with it is that the mast flexes (I can deal wit some) but also tordates and that sucks. This will probably less/not the case with lighter riders, but for me it just not stiff enough.A friend who was winging behind me told me later how it looked like that the mast was like a Hawaien Hula hula dancer below me where my cedrus is almost like rigid.
Hi @jeroensurf
Super thanks for this review and the one on FB (the translation works well enough). I was thinking of going for a Cabrinha as my surf foil. But I'm not sure now....
@Rod,What might be an option, is getting an foilparts adapter and use the Cabs with a Aloy Axis mast.That works great and yes the Axis aloy and Cedrus mast feel a tiny bit more draggy as the Cab 2023 mast but the extra stifness ads soo much control that I prefer these.
(but there are also soo much other good foils!
Half a year ago I was thinking about replacing my Cedrus with an faster mast, but the more stuff I try the more appriciate the whole Cedrus package.
I feel for the designers, they are never going to please everyone with rider weight, skill and conditions so variable. Jumped back on the 19mm Axis mast yesterday and could feel the extra drag at speed compared to the Cabrinha hollow. It wasn't an issue just cruising around but every little bit counts when you're chasing a wave down, cranking up for a big jump or taking a big drop.
The side bolt definitely improves the joint stiffness and will help with keeping it tight over time but if your mast to fuse join is already tight then you won't notice a difference. Carbon is soft and wears down over time, I use to give the old mast inserts a couple of coats of epoxy when play crept in but with the clamping effect of the side bolt I haven't had an issue.
@jeroen thanks. Just getting rid of all my Axis stuff and trying something different.
Ultimately looking for a platform that I can bolt on a racing wingset (600sq cm ish foil) and a more everyday 1000).
I like the look of the Cabrinha foils and I know the 650 is fast-ish. But don't want a draggy or bendy mast.
If I were going to do this I would put a hole in 2 12" long pieces of plastic or cardstock, and aggressively tape them to the side of the mast far enough up and tight enough that the position won't shift, with the holes over the mast screw holes. This should allow precise hole positioning when you put the fuse on. Assemble the bottom section onto the mast and use those holes as your drill/layout guide.
I cracked a gen 1 fuse and cut it apart and there's nothing inside of the fuse that would prevent this from working or anything critical that would be compromised by this mod.
