We had not been under way a quarter of an hour before it became apparent to everybody on board that the _Europa_ was going to more than justify the exceedingly favourable opinion that we had already formed of her; for, light as was the wind, she slid through the water at a speed that fairly astonished us, her keen stem cleaving the short Channel surges cleanly and with very little noise or fuss, and leaving behind her a wake so smooth and so little disturbed that at a distance of a quarter of a mile it vanished altogether.  And when, an hour or so later, having made a good offing, the skipper ordered her to be hauled to the wind on a taut bowline for a short time, to test her speed under those conditions, and then put her about, she went to windward and tacked like a yacht.
