George's Channel is very much like the English Channel, except that between Port Patrick in Scotland and the Irish coast the waves are more regular than between Calais and Dover, where currents and banks tend to make dangerous cross seas. So it is found that off Plymouth and Falmouth and outside Dartmouth there is often an ocean swell running, especially after there has been a south-westerly gale. The Solent, again, is different from the Clyde in its sea disturbance, and when acted upon by a south-easterly gale the seas off Spithead, owing to the shallowness of its water, have not nearly so much weight of water in them as those of the Scotch estuary when worked up by a northerly or southerly breeze. The Liverpool and London rivers are very much alike, though perhaps of the two the Liverpool has the greater sea disturbance, owing to the strength of its tides, which at some seasons are very rapid. To large yachts of 40 tons and over the difference in character of the seas just spoken of is not a matter of great importance. What a large yacht may treat as a mere ripple to a 5-tonner may be a 'nasty sea'; and as these pages are dealing with the smaller craft of about 30 feet length, the sea disturbance must be regarded as it affects them. On rivers and inland waters the waves, as a rule, have not much weight in them, and there is no reason why the small yacht should not be able to go through the waves she is unable to rise over. Yachts of large displacement are more likely to do that at better speed than a small vessel of the same beam and length, because they have more weight. Where ocean rollers are concerned, or a heavy swell, while there is wind both types may be equal; but when the wind is shy and light, then the yacht of large displacement will walk past her small rival. It would be noticed that the heavy displacement vessel would forge ahead apparently moved by no other force than the 'send' of her weight as she lazily pitches to the movement of each succeeding wave. The courses for small yachts where such conditions are met with are Plymouth, Dartmouth, and Queenstown, and some parts of the Clyde and St. George's Channel to a very much lessened degree. Then, if a thought be cast across the Atlantic and a look be taken at the characteristics of the waters of Long Island Sound, that favourite haunt of all American racing and cruising yachtsmen, as on our own inland waters, the seas that much disturb the small fry are, it will be observed, scarcely noticeable to the large schooners and cutters of which so much is heard. The principal form in America laid down for all yachts used to be a long flat floor with very small displacement, great beam with a centreboard--the immense beam giving great initial stability. Large as well as small yachts were built to this design, and much used to be heard about their remarkable speed. A few years ago, however, two or three small yachts, amongst them the little 'Delvin' 5-tonner, built by Mr. W.
