They are not confined to Kingstown Harbour, however, as they have sent representatives to the River Plate, Hong Kong, the Persian Gulf, Australia, and many foreign ports. Their principle has been largely adopted in the B division of the Dublin Bay Sailing Club, which consists of 18-ft. boats, called 'Mermaids,' which are practically large Water Wags, being entirely open, with 6-feet beam, fitted with centreboard and carrying no ballast. These have a limited racing sail-area of 180 feet, but they are not further confined as to shape, and some have the rounded stern and some the square. They are very fast, lively boats, requiring a crew of three or four nimble hands, principally to be employed in shifting ballast, and they give a great deal of sport, as many as twelve or fourteen starting in a race every Saturday afternoon. The 'Water Wag' costs complete between 15_l._ and 20_l._, a silk racing lug from Lapthorn and Ratsey alone coming to 2_l._ 15_s._ McAllister, of Dumbarton, built most of them; but Atkinson, of Bullock, Co. Dublin, and Doyle, of Kingstown, have built many more. In handling, the skipper--especially if he is a tiro at the art--must be very careful, as 75 sq. ft. of canvas, and a 13-ft. mast in a 13-ft. boat, without ballast, require attention and caution if there are any puffs knocking round; so that the mainsheet must never be made fast, no matter how fine and calm the weather is; the halliards should also run very free, and the oars should always be carried, in case it becomes judicious to lower the sail in a squall. But a little practice will enable the skipper to sail his boat without danger during weather that any small open boat can be out in; and it is really marvellous what weather and seas the Water Wags have gone through. Sailing out of sight of help in any small open boat is to be deprecated, and no exception to this rule is to be made with Water Wags, as they unquestionably run a risk of filling in unskilful hands; but, in that event, the absence of ballast is an advantage, for they do not go to the bottom as a ballasted boat will, but will actually support their crew if no attempt is made to climb up on them. A lug of 60 sq. ft. is ample to begin with; and for most days when not racing, and for single-handed sailing, a reef should be taken in, or two kegs of water-ballast carried, unless on a very fine day. The following sailing regulations are carefully enforced during racing:-- Only the boats of members shall compete in the races, and as it is one of the fundamental principles of the Water Wags that the boats shall be similar in every respect save sail-plan, it shall be in the power of the officer of the day to disqualify any boat that, in his opinion, is trying to gain an unfair advantage by infringing the above principle.
