I've tried to but the best I can do is to pop the hull out of the water for a couple seconds.
If I sit on the wing, the leeward hull gets pushed into the water so hard that the wing mounts dig into the water and really slows the boat down. That kind of defeats the whole purpose of lifting the hull to reduce drag and get more speed.
If I sit on the hull, there is less leverage/weight and the hull comes up easier. But the problem is that the wing that I'm up against with my back prevents me from leaning outwards. So I have nothing to prevent me from falling towards the center of the boat. I can't get my butt over the edge of the hull.
I'm guessing I'll have to remove the wings so I can sit on the edge and lean out if I want to lift a hull for max speed.
Anyone regularly flying a hull on the getaway have any tips?
Yep, do it all the time with and without wings (though without wings is more fun in my opinion)
First off, if you want to fly a hull to get more speed you should just get it off the water and keep it there (more on how to do that below). Seems that you are flying it to high if you get the other wing on the water. You can also lift it a lot more for added fun though you will be going slower (with the wings on the boat will slow a lot when the other one hits the water of course).
If you are sitting on the hull, the way to not fall off is to use the hiking strap, that is you can put your feet over the strap instead of under it, and then you'll be able to fly very high while being practically standing on the strap. Actually even if I don't have the wings on I put one foot under and one foot over the strap so I can do the same.
Now, how to control how high the hull flies? Pure mainsheet control! You just gotta never cleat the mainsheet, you pull it in and out so as to maintain the height you want. If the hull starts falling you pull in, if it starts flying too high you sheet out..... you gotta anticipate a little bit though because the boat can be slow to respond... it just takes a little bit of practice. It is better if one person is doing the tiller and the other one the mainsheet so it is less work (sheeting in and out with one hand can be tiring). Also watch out the mainsheet and don't let it go in the water. If so it'll pull back and it can be very difficult to release it, potentially leading to a capsize (though that is fun also; I did it this weekend).
