For many years I've predicted that sooner or later foilers would be designed that could safely jump and safely re-enter. We've all seen that already with foiling windsurfers and kiteboards but now it is being predicted by David Smyth, President of Westlawn Institute. His comments below from Scuttlebutt are in response to the question whether or not foiling represents the future of sailing:
YES: The current foiling technologies are extremely limited and dangerous. However, foiling will very soon be very safe and more than twice as efficient (L/D) than current foils. This is because we are starting to develop the computer controls for fully active control with digital control laws that change very rapidly to deal with real-life events: wakes, seaweed, debris, etc. We will soon be able to do controlled jumps. That is a fundamental minimum capability for safe foiling.
Full foiling boats will look completely different from any current monohull or multihull: the problem of flight is fundamentally different from the problems of floating vessels, and so the solutions will be fundamentally different. Our current R&D efforts are bringing aerospace software and avionics technology to bear on this problem, and the progress is rapid and very promising. NDAs and proprietary corporate investments are currently restricting what can be shared at this time, but the efforts currently underway will bear fruit and be widely publicized and demonstrated in the very near future. -
First picture is an accidental jump that was due to rudder and wand problems BUT that I think can be duplicated now at will.
Second picture is a controlled jump with safe re-entry:
