1) When you are going fast relative to the wind speed the apparent wind is often from straight ahead when you are straight down wind (true wind). This makes it harder to make the sail flip. Yes some times you need to push the boom around as you keep turning to get it around particularly if you turn fast. I try and get the sail eased to 90 degrees or more by the time I am pointed straight down wind.
2) When you get turned back towards the wind it is often because you are not easing the boom out soon enough. Moving the back foot outboard will help turn the board. Steadily Increase your foot preasure on the inside of the turn all the way to the end.
Another way to think about it is that back hand preasure before the sail flip slows the rate of turn. So you have to ease off the throttle to get the board to turn. Learning how much and when to ease in relation to the rate of turn is the key to making the transtion.
The bigger wing will be tougher to turn.
Keep foiling often and keep going for the gybes, it takes time, patience and persitance. The effort will be worth it! Best of luck!
Regarding #1 the faster I am going the easier it is to flip the sail especially if I over sheet going into the gybe, its only at very slow speed that the sail flip is an issue.
#2 when you say outboard with the back foot, do you mean across the centre line towards the leeward rail?
Okay first take everything I saw with a grain of salt. I can make most of my foiling gybes but I am no expert. Describing things to others helps me learn.
Reagrding # 1
I see two different ways approach the sail handling in foiling gybe. Both styles do two important things; they shut off or reduce the sail power that is preventing the board from turning and they prevent the sail from getting back winded which will really stop the turn.
A) Ease and Open the boom early
See Sam Ross vid:
I think this style is more forgiving to beginners and it helped me learn. Sailing from a broad reach to a broad reach makes a short and easy transition. You can still carve hard and fast with this approach you just have to let go of the back hand early and completely so you coast through the turn while carving hard. I finding that this style works better with more wind.
B) Over sheet and throw
See Phill Caneri's vid:
Phil sails into the turn on a fast reach he over sheets then he CHUCKS (throws) the sail forward to flip. He switches feet after flip sailing out on a reach. This big but hard and fast turn limits the time spent without sail power which is probably good in light air.
Try and track the difference between your speed and the speed of the true wind. If you get wound up to 22 knots and start your gybe in a lull of 6 knots the apparent wind will be from straight ahead and over sheet and throw is probably the call. This is a just an example, don't gybe in lulls you want to gybe in the gusts until it is nuking.I
f you are making 22 knots in a 25 knot breeze the apparent wind is much further aft and the sail flips itself. Ease and open will work here and so will over sheeting probably without the need to throw.
Both styles have their time and place.
Regarding # 2 Yes by outboard I mean across the centre line towards the leeward rail. You get more leverage to turn the board.
I hope this helps!
