As regards the sail-area, an owner should hand the sailmaker's certificate to the official measurer and give him every assistance in measuring the yacht's spars, &c.; and, subsequently, should any alteration be made to the sails or spars affecting the yacht's rating, the owner should at once inform the secretary Y.R.A. in writing, and return the certificate if required (Rule 3). In short, an owner is held responsible for the rating of his yacht being absolutely correct. His next duty is to enter her properly for any race he may wish to compete in. 'Entries shall be made ... _at least_ forty-eight hours previous to noon of the race day'--twenty-four hours being added for a Sunday. Clubs have asserted the right to close entries at a longer interval. Owners must therefore note these times for closing the entries, and act accordingly (Rule 5). Post entries are not provided for in the Y.R.A. rules, and must therefore be considered irregular, whether sanctioned by the other competitors or not. The long declaration given in the rule is a nuisance, and should be cut out, as there is no reason for mentioning one rule more than another on this declaration. So long, however, as the Y.R.A thinks it necessary, it must be enforced, and owners should help the clubs to do so by carrying it out. As before stated, an entry by telegram (_sent off_ before the hour of closing entries) should be followed at once by this written declaration. An owner should know that if a race be postponed or resailed all the yachts _entered_ may start; but the entry is closed to other yachts (Rule 5). [Illustration: ROYAL SOUTHAMPTON YACHT CLUB. "BRAMBLES AND LEPE COURSE."] An owner must belong to some 'recognised yacht club' or his entry is void. A hired yacht cannot be entered for any race under Y.R.A. rules (Rule 6). An owner cannot enter two yachts to compete for one prize, but he can enter one yacht for two simultaneous races (Rule 7). An owner who has entered his yacht for a prize may sail over the course for half the value of the prize should no other competitor start (Rule 8), and should the race officer not postpone the race for bad weather (Rule 2). The owner (or a member of a recognised yacht club, to represent him) must be on board during a race, and after the race he should sign a declaration that the yacht has been sailed in strict conformity with the Y.R.A. rules and with the conditions on the programme (Rule 10), and forward same to the race officer at once, or to the secretary if later. An owner (or his representative) should see that his yacht is supplied in good time with the written or printed instructions for a race (Rule 12). Should an owner (or his representative) decide to protest against a competitor, or otherwise (removal of a mark, for instance), the protest-flag should be displayed at the proper time, and the protest in writing lodged without delay. Certain time-limits are given in Rule 30.
