Do mast adaptors measurably impact stiffness or other mast characteristics?

I’m considering buying a mast from OceanSportsAustralia and using it with an adaptor to fit my existing Duotone foils.
I was wondering whether using an adaptor affects performance in any way. For example, does it make the setup less stiff? Or are there other aspects I should be aware of?
Obviously, it will depend a lot on the quality of the adaptor, but I’d love to hear from anyone who has used an adaptor and what their experience has been.

I have really high expectations of gear and haven't had any complaints with the One Ocean mast and adapters. I use Lift and Code because the adapters are so clean. The One Ocean mast is outstanding and upgrades those foils for sure.

Some people struggle adding aluminum to a saltwater system. Adapter quality is critical, there are some awesome DIYers out there making really cool stuff that most people never see or hear about.

My oneoceansports mast and code adapter is rock solid, I recently upgraded to a titanium one.

Agree, used both aluminium and now titanium adaptors.

Rock solid, no movement and great tight fit btw mast / adaptor and fuse

The SS is a great mast, especially with bigger spanny foils of 1300-1600cm2 its stiffer as most.
Duotone has a saddle type of mastconnection. I have the same with AFS and you can get adapters from that from Jim Stringfellow.
The positive is that the connection is stiff, the downside is that it is notticeable more draggy compared to the AFS UHM80 without the block of aloy inbetween the mast and fuse.
I can,t say for 100% sure its the adapter, but with the same fuse and foil and both masts have aprox the same diameter and overall cord it seems to be the most logical conclussion to blame the extra thickness arouund the head caused by the adapter. Because I really liked the extra stifness of the OO mast
I asked Stringfellow to make me a custom fuse: axis/one ocean head to AFS foils but unfortunally he stopped making custom fuses for now.
Bit of a pitty because with the adapter the excellent OO SS mast is not gonna be used so serious considdering switching to a foil brand like Code (S2) where the adapter falls into the fuse or switch brand of DW/supfoil foils including mast.
I demoed the Naish Excalibur and really really liked that one for its insane low end.

Thanks Jeroen, it is really useful to know. That's what I was afraid of, the adapter looks very chunky, significantly bigger than the original connection.
Good to know that the stiffness is not affected . Thanks Mikedubs and IANC . The chunkiness of the adaptor does give me pause since one of the reasons to switch to the mast is to reduce the drag.

Thanks Bryan, good point. I didn't think of that.

It’s not the salt water it’s the fact that carbon and aluminium are about as far apart on the galvanic table as u can get. They should never ever touch. So foils designed for ally masts had some glass at the junction. Just a bit.
full carbon systems may or may not so you’re taking a risk with an adapter. Not a big issue as it’s only touching when in use, I’d just be religious with disassembling and inspection of all fittings, even ones elsewhere on the board. EG I’ve seen a stick on shark repellent system cause full thickness corrosion in fin bolts on longboards

Titanium what? Im looking at the SSS 84 for my CODE and still have my alloy Stringy adapter, but it has corroded a bit and I was never really 100% comfortable with the shallow threads for the M6 fuse bolts

There is no extra drag, the adapter sits fully in the Code fuse

Adapter. You don't have to stick with the aluminum one anymore.

Has anyone here gotten the ti adapter from One Ocean yet? Or did people here get the small batch that came from Progression Project?

The screw length, while disconcerting, has never been an issue in practice over two years of use. I did make some custom length M6 that catch about six threads without bottoming out. You could theoretically drill into the carbon foot to allow a longer screw. Could even install helicoils in the mast foot but it would be a tedious process for little gain.

The only real benefit would be if you lose a screw it would be easily replaceable with a more common length.

I have the Ti adapter from progression forum that I use with a OO mast and it’s super tight fit, it’s as stiff as with a code mast. I did drill 2 tiny holes in the mast so I could use M6 16mm screws. No issues even though yes the screws feel small.

I am still waiting for my Titanium adapters so any out there out there at the moment will be from the progression project order.

@paul.j, would you consider doing a mast with cedrus foot so that their adaptors could be used? They have way more options than Stringfellow and it looks like their adaptors are generally less chunky.
