I am not sure if anyone has done this before. But mix and matching mounting plates and masts can save a fortune. We already know that Takuma and naish us the same mast dimensions. I can now add Gong to that list. They are not a perfect match as the gong mast is slightly loose in he Naish plate and the Naish fuselage - but some judicious shimming is all thats needed. I am currently using the Allevator with a naish mast - its a really tight fit so best done with caution. The pitch of the mounting holes is perfect.

To be honest - I would recommend shimming anyway the tighter the fit the less likely it is to break and it will make your pumping more efficient.

The Shinn mast fits nothing I know of - it uses only 2 bolts.

The manta mast is also 2 bolts but at a different pitch.

Any others to add to the list ? I add this as I am one of the dumb asses that bought a probox board - and really hoping I can find a way to connect to it ! Seriously thinking of going into production to make adapters to connect any mast and any board mount to any foil - I can't be the only one pissed off at the lack of compatibility.

measurements to follow
