I was about to add a new 460 rdm mast to my present 430, but I see that Ezzy now sells tops and bottoms separately. It would be cheaper go this way. If I buy a top, it would go on the bottom of a cc a mast of another brand., though. By the way, would it be better a new top on the existing bottom, or the other way around? I guess I shouldn't worry, because I am not a demanding expert, just a run-of-the-mill intermediate sailor, but I'd like somebody to comment on this.

Thanks ,

I'm not sure different brand masts are interchangeable. I guess you could try it out first. What if you want to have two sails rigged?

You generally can't mix brands, frequently you can't mix models within brands.
If you are on a budget buy a used mast.

Hi Franchetto ,on the Ezzy website it says to use or change the bottom piece ..it kinda makes sense as the bottom is the stiffer of the two .if I take my 8,0 Lion and my 6.5 I take the 460 Ezzy RDM with the 430 bottom which gives me 445 luff on the 6,5 is 458.

But the Ezzy ferrule is opposite to most

probably to avoid people trying what you're suggesting as it's not a great idea. They came up with mix n match but know other brands won't work.

I believe Patrik masts have interchangeable tops & bottoms

Yeah you can do the same with Severne RDM wave masts too. I have done that previously when I didn't have a spare after noticing a crack in the bottom part. It works as a temporary option, but it's never ideal as the sails are designed to work on the specified mast.

As per above, you're probably better off buying the 460. Knowing that the half's are interchangeable, you have options when you break something down the track.

Goya says that you can mix mast parts, too
