Of course, the raison d’être of the E4 is its sailing chops, and once underway on Chesapeake Bay in light airs of 5 to 7 knots, the boat did not disappoint. Upwind, on a slight heel, the articulating foot mounts abaft the twin wheels were very handy, and the helms were light and sensitive as the boat clipped along at about 4 knots. But she really came alive once the asymmetric kite was up and drawing, charging along on a tight reach while making 6 knots. Impressively, despite the wind angle, the helm did not load up and remained very responsive, and the chine made it impossible to bury the rail, despite our best efforts to do so. It was like carving a turn on a pair of Elan skis, right on the edge yet in complete control.
