I don't mean a daggerboard fusilage that touches the water surfaces but which is in the air. If the surfaces is big enough it can replace the function of a normal daggerboard because the angle of attack of the wind on the level of the plane is more forward than that of the angle of attack of the wind at the level of the kite. It will become a real "aerofoil"
And I mean you need bigger models when doing it rc because you need long lines to have wind difference between the kite and the plane and so you need a big kite and therefore a big model if you know what I mean. But it can be rc probably. But maybe small differences in height are enough for models. I am not that much into the numbers. Because you have lift of the kite you don't need as big a wings as a glider and maybe even wings that can create downforce. Maybe that's what Jon means. But you need wings for control. You can gain speed sailing in a normal way, Then the direction of the apparent wind becomes closer to the direction of moving and the transition of water to air is not so dramatic. These are my idea's. I don't understand how Jon plans on using a lift boat. Maybe he uses his monofoil concept to gain control over the height of the craft. His monofoil is in fact a glider under an angle . Maybe he uses that to counter lateral forces. But his models are inherently stable on the water, but will they be in the air hanging under a kite or will it need rc. I would be glad to receive also a copy of your sketches Jon. I think I know which way you are going, but I still like to see it. You have my email. Best regards, Johan
