THE FLYING PROA FROM ANSON'S "VOYAGE. 1 
or persons, who may be aboard when the measurement 
is being taken, stationed amidships. 
If any part of the stem, sternpost or other part of the 
yacht below the load waterline projects beyond the length 
thus measured, such projection shall be added to the 
measured length; and a form, resulting from the cutting 
away of the fair line of the stem, sternpost or the ridge of 
the counter for the apparent purpose of shortening the 
load waterline, shall be measured between fair lines. 
The measurement for load water length shall be made 
with the same number of persons on board as are al- 
lowed for crew in the yacht's class, whose average weight 
shall not be less than isolbs.; or, at the option of the 
measurer, with a dead weight equivalent thereto. 
The measurer at the time of taking his measurements 
shall affix a metal plate as a distinctive, permanent mark 
at each end of the load waterline. 
3. The beam shall be taken from outside to outside 
of the planking on the broadest part of the yacht, and 
no allowance should be made for wales, double-planks 
or mouldings of any kind. 
4. The girth shall be taken from L.W.L. to L.W.L. 
under the keel at a point 0.6 of the distances between 
the outer edges of the L.W.L. marks from the fore end. 
The girth shall be measured along the actual outline 
of the vertical cross-section at that point at right angles 
to the L.W.L. If the draft forward of that point exceeds 
the draft at that point, twice such excess to be added to 
girth. In taking these measurements all hollows on the 
fore and aft under water profile of the vessel to be treated 
as filled up straight. 
To the girth of centerboard yachts must be added 
twice the distance between the lower side of the keel to 
the center of the area of the centerboard when lowered 
to its full extent. Centerboards when ballasted, except 
to overcome flotation or fitted with bulbs or otherwise, 
to be measured as fixed keels. 
Measurers shall mark the points for measuring the 
girth as follows: By fixing three metal plates of suit- 
able size on each side of the yacht not less than 2in. or 
more than 6in. above the L.W.L., level and parallel 
thereto, and not less than 3ft. or more than 6ft. from 
end to end, so that the center mark of the three coincides 
with the distance 0.6 from the fore edge of the bow 
marks. 
The measurer shall also place a plate coinciding with 
this center mark under the rail or covering board, and 
another on the side of the keel perpendicular to the 
L.W.L. level. The distances between the L.W.L. level 
and the horizontal marks to be measured when the yacht 
is afloat in smooth water and deducted from the girth as 
obtained from center mark to center mark. 
Measurers may accept for the measurement of girth 
the designer's written certificate or drawing certified to 
as being correct by designer and builder. But this shall 
not relieve the owner from fixing the marks heretofore 
described, or relieve him from the responsibility of the 
accuracy of the certificate and proper position of the 
marks. In the event of a measurement protest the yacht 
must be measured as heretofore provided. 
5. The sail area shall be ascertained by taking a 
perpendicular along the after side of the mainmast from 
the under side of the sheave of the highest halyard block 
or sheave on the topmast to the upper side of the boom, 
when resting on the saddle or on the lowest part of the 
gooseneck, the distance of which point from the main 
deck or house deck shall be recorded by the measurer, as 
well as the other points used in measurement. 
The forward point of measurement of the base line 
shall be midway between the intersection of the bowsprit 
and jibtopsail stay and the center of the tack cringle of 
the jib or flying jib when set. The after point of meas- 
urement shall be the outer end of the main boom in 
schooners, cutters, sloops and catboats, and of the 
mizen boom in yawls. 
The niaintopmast shall be measured from the hounds 
of the lower mast to the under side of the sheave of the 
highest halyard block or sheave on the topmast; 80 
per cent, of this length shall be taken from the ex- 
treme length of the main gaff measured from the inside 
of the jaws to the outer end, and the remainder shall 
be added to the base line. 
In all cases where the length of the spinaker boom 
exceeds the distance from the forward side of the for- 
ward mast to the forward point of measurement, such 
excess shall be added to the base line. The length to 
be taken for the spinaker boom shall be the extreme dis- 
tance of its outer end from the center of the fore side 
of the mast, on which it is carried, measured when the 
boom is in place for use. 
In pole-masted yachts and those not carrying topmasts 
the distance between the under side of the sheave in the 
throat halyard block and the under side of the sheave 
in the uppermost halyard block or sheave on the mast 
shall be used for determining the length of the base 
line in the same way as is the topmast when one is 
carried. 
In yachts which do not carry headsails the forward 
point of measurement for the base line shall be the 
after side of the mast, or of the foremast/ if there is more 
than one mast. 
The sail area from these figures is obtained by mul- 
tiplying the corrected base by the perpendicular and 
dividing by 2. 
Where m any case, owing to peculiarity of rig, the 
sail area of a yacht cannot in the opinion of the meas- 
urer be fairly measured in the customary way, he may 
with the sanction of the race committee take such meas- 
urements as will enable him to compute the actual area 
of sail carried or that may be carrid in the spars used. 
The prescribed method of measuring shall, however, 
be adhered to in all cases where practicable, and where 
the leach of a sail is extended beyond a straight line, or 
where, as in a lug mainsail, the luff extends forward of 
the mast or the head is rounded, the increased area 
resulting shall be added to that obtained by the cus- 
tomary measurement. 
6. The racing measurement of a yacht launched after 
Oct. 1, 1898, shall be assumed to be the maximum limit 
of her class. 
7. If a yacht after having been officially measured be 
increased in load waterline length, -beam, girth or sail 
area, the yacht must be remeasured before starting the 
race. 
8. If through protest the measurement of a yacht be 
called in question, the race committee shall direct the 
measurer to remeasure such yacht, and the result as re- 
ported by him shall be final. The usual fee for measur- 
ing shall be collected from the owner if the measure- 
ment be found to exceed the measurement filed; and 
from the person protesting if not. 
The owner of a yacht so protested shall present his 
yacht for measurement immediately after the race, when 
so required by the race committee. 
9. A yacht whose official racing measurement has 
not been filed with the race committee prior to the start 
of a race shall not eligible to compete. 
Classification* 
All yachts shall be classified by racing measure- 
ment, and shall be divided into classes as follows:

not over 100ft., and over 80ft. ; Soft, class, not over 80ft 
and over 65ft.; 65ft. class, not over 65ft.. 
Sloops, cutters and yawls: First class, all over 65ft.;
