Mast compatibility

So I know most of the base plates are 90mm and if you have a track system you can swap the entire foil kit, mast, fuselage and wings over from one board to a different board.
But today I heard that the Naish and Liquid Force masts are also compatible. I find this a little hard to believe, as the mast sizes and bolt places should be all different. Anyway, is this just a bad rumor or are some of the masts actually compatible between brands? I have a liquid force setup so I can measure that but no access to a Naish right now. If the masts are compatible that makes shopping for a short mast and not having to tap new holes easier.

== edit: corrections made now ==
The current Naish foil parts series is called "Thrust" and uses a 3-screw mast, not compatible w/ LF and not compatible with Hover.
Naish "Hover" (ie: 2017) foilsets use the same fat crappy mast as the old LF "foil fish":

Shown above, those old "foil fish" orange LF masts are thicker than the (below) LF Rocket, Happy, and today's other current (black color) aluminum masts.

So in conclusion, I haven't found any example of todays LF masts being used under brand names besides LF/Wakefoil/RideEngine/CloudIX.

Since 2017, a few manufacturers have moved to the same standard: 3 screws spaced by 4cm : RRD, Takuma, Naish, Gong (55USD for 65cm mast), Airush … The mast is held by 3 screws diam 6mm, the fuselage is held by 2 x 6mm screws (could be 3). This profile is not symmetrical as profile max thickness is located at 40-45% from and closer to leading edge.

Masts are now 40/65/85 for the hi rise system. They have been stiffened up starting with the recently launched Hi Rise Varial and Carve foil kits. Previously, masts were 40/60/85. All masts are fit compatible from 2017 forward, but the 2020 masts are stiffer. Speed and Lift were launched in the 2019 product collection. The 2020 Lift will be reworked to fit on the new fuselage that is currently shipping with the Varial/Carve, as is the Speed. We had to change the fuselage to accomodate stiffness at the front connection as well as adding a third bolt. The pedestal mount has two sets of holes: 1/ regular countersunk holes to bolt into a track, and 2/ threaded holes designed to work with our through-bolted Double Agent board (bolting from the top of the board). The Track countersunk spacing is 90 x 110, while the Double Agent threaded is 90 x 140. I have no idea if the mast is compatible with another manufacturer, but the platform was shared with the now defunct CR:X.
