Hey guys just wondering if anyone has a good explanation for how foil rake(angle between board deck and foil) affects control and ride characteristics, I've noticed that a lot of the professional wing racers have a fair few degrees and ik the kiters have a lot as well
Here is a couple of explanations one by Sam Ross and one I did few months back.
For example, I had a large slow beginner front foil, I shim it so the foil points more down when facing forward, I could get more speed and less 'over' lift and so use the foil in stronger winds. Works both ways the shim either way round either gives more lift or more speed, a very economical way of extending foil range if it works well for a given foil setup.
What kinds of angles are we talking about? The omen video suggests starting with 1 degree.

Around 1-2 degrees probably
Hi guys, new to this, I'll drop here my 2cts. In general, pro racers want to reduce front foot pressure at high speed to gain control and being able to push even harder and faster. To do this, almost all race boards have rake in the bottom. Angles really depend on the foil they are riding and the designed AoA, but they all have more than 1 degree. I'll work with a couple of wing racers and for one guy I put 3.5? and another almost 5?. However, the easy way to explain it is: If you fly nose down, you will notice less front foot pressure and if you fly nose up you will notice more front foot. For normal people zero degree is what works best for the majority of foil cause they are almost all designed for flat mast plate.Another thing is changing the angle in between your front foil and stab that will have another effect....

if they want to reduce front foot pressure then why do they add nose up angle then?
