I have only sailed the 720 for two short periods, I used the 720 that belongs to steve above in his detailed post, I need to try his 720 again to trim the mast position and maybe use a tiny shim to get it right for me,the shim steve has used in the second test was too thick for me,
but there are very stark differences to the 590 which I did own for 6 months.
so my comparison is missing much detail.
The big shock is the explosive lift in little wind,much much more than the 590, the wind on testing day one was maximum 8 knots and dropping to near nothing a few hours later, so the the fast rise from the water was pleasing as it then just shot off at high speed with silky smoothness, delivering long smooth drawn out carves, the wide arc of the carve was very stable, super stable, upwind felt fast, high and locked in, much faster smoother response from low to high speed than I remember my 590 was, and far more stable, very little twitch or wobble going into a turn,
but the 720 needed trimming for me to push it to higher speeds as the lift was too hard, too far forward for high speed control, with trim dialed in for me then I am sure the 720 will hit very impressive sustainable speed.
before anyone asks the foil sinks quickly, and will not float the board on its edge,
It's one of the nicest looking foils out there, it just looks so fast and sleek, but not flimsy fragile, fitted to the fuse and stab its still very light, not as light as the 590 but looks and feels less fragile, the tips are strongly made, not as easy to chip as all the earlier moses wings with super thin pointy ends.
if the wind picks up today we will be out again for day 3 test.
