Here is reason for rake from Armstrong ... Performance masts are designed with a mast rake angle. This fine tunes the board angle relative to the foil for a more comfortable and forgiving ride. It does not change the lifting force or balance of the foil itself, and it does not impact the foil’s “foot pressure” bias front or back. Board rocker also directly determines effective mast rake - boards from different brands have a variety of different rocker lines which influence rake angle - and more rocker in the rear half of board effectively increases mast rake. The 1 degree of rake we’ve placed specifically into the top of the Performance Mast shape provides three main benefits by adjusting the board relative to the foil underwater: By bringing the foil closer to 0 degrees when the board is in the water, drag is reduced which makes takeoffs easier. Touching down at speed or landing a jump is more forgiving and there’s less chance of crashing headfirst over the board. By lifting the board nose slightly (1 degree = 17.46mm/m), mast rake makes it easier to ride fast without catching the nose at steep riding angles. Simply put, the Performance Mast range takes the sublime Armstrong feeling further than ever :)
Thank you so much for this info. It doesn't reflect my experience with my board, but it's interesting nonetheless and makes me want to try again. May I ask you where you found this? Thanks!
@@gcammar maybe your board did not have flat box parallel to the deck. In other words maybe you already had mast rake due to already having rocker which means you had to shim the rake out of the mast as you had too much rake. This comes straight from Armstrong website under the performance mast technical info.
What front foil were you using and what tail/shim? The new MA wings are set to match rake of performance masts but as far as I know older HA wings were different by 0.5 degree.
Did that mast shim come with the performance mast or is that something you made/had made? I'm actually interested in shimming the mast on my current non performance mast to mimic the 1 degree angle for winging takeoff enhancement on my Armstrong board. Thanks!
other than that setup I mention (24.5 mast and GL120 for SUP foiling at one particular spot), I don't ride Gofoil anymore, so I don't know the answer to your question
Arnie said mast rake angle makes foil more parallel to surface with lower drag when building speed to get on foil.
Another incredible review! Stoked!
love the review. I think I will get the 935 for kiting.

@@Mickfoil1 thanks. My board has completely straight rocker, so, once again, my experience is different than what the website says.

thx for the time spent and the review! What about the beveled tips on the new Go Foils? Are they game changers as Alex Aguera claims?
