The Red Wing has a fixed collar/flange on top of the mast that gives a default mast rake of 0,3 dgr.
In my opinion 0.3 is too little I want minimum 1.5 dgr. In order to get that I can either put a 4 mm shim under the front screw in the foil box, or put a shim between the collar/flange and the board?!
What is best? Do any of you adjust the mast rake of the Red Wing?
Any experience with mast rake adjustment on Severne Red Wing is welcome.
Pls no general comments on mast rake or mast rake on other brands etc. this thread is exclusive for Severne Red Wing
Thanks
I would not put a shim between the flange and board, was not designed for that and you will point load the flange, If you have a shim for the foil box, why not use it?
I would not listen to Sandman, even though he is correct in this rare instance.
Adjust the pitch of your foils if needed (although you shouldn't have to) Best to not mess with mast rake.
I'd be surprised that there's that little actual rake in the foil rather than just the mast. While we refer to "mast rake", what we are actually adusting is the angle of attack of the foil vs the bottom of the board. The simplest way to do that is, of course, by adjusting the mast. One can also shim the front wing but that also necessitates adjusting the stab by the same measure or you really start complicating things which is why the mast adjustment is ultimately simpler.
Could you satisfy my curiosity and verify you are actually measuring the angle of the fuse vs the angle of the bottom of the board rather than just the mast vs the board? Masts are not always set at 90 degrees is why I mention it.
Plates can be shimmed minimizing point load. Shim for a similar foil "plate" for example. Not sure this would fit the Redwing but if you have access to a 3d printer, it'll serve as a model.

I would not use a mast flange rake shim like that one posted by Paducah for the AFS foil with carbon mast flange, unless it was offered by AFS, because they would know if their mast flange could handle it. And that is especially true for Redwing since it is an aluminum mast flange. If it is a foil box, then you want to adjust foil angle using a shim in the foil box, because that is how they were designed to be adjusted.
I made a 2.0 dgr mast rake today with a shim between the flange and the board.
First impression is that I had less touch downs in the lulls as the nose fly higher. The wind was shifty and the water pretty flat.
I'm looking forward to try it in more chobby conditions where I expect it to work even better.
I'm also planning to do a shim for 1.5 and 2.5 dgr inprder to fond ehat works best for me ??
