The Yacht Racing Association of 
Massachusetts. 
As the result of a good deal of labor during the past 
two months, the Y. R. A. has adopted the following new 
regulations. The ends aimed at are the same as in New 
York, the restriction of extremes of design, construc- 
tion and arrangement in the interests of the majority of 
yacht owners who wish to race in yachts suitable for 
general service, The feeling on the part of a majority of 
the small yacht owners about Boston has been strongly 
against all formulas and especially against the use of sail as 
a factor, the measurement of the Y. R. A. since its or- 
ganization being waterline alone. In the new regula- 
tions an attempt is made to place values on other fac- 
tors of advantage, the beam, ballast and sail area, by 
means of special new formulas, as given below. These 
formulas are merely auxiliary to the actual measure- 
ment rule, which is still the waterline only. By this 
method, which is at least a novelty in measurement legis- 
lation, a yacht of a given waterline is allowed to carry 
sail in direct ratio to her beam, while she must also carry 
a minimum weight of ballast, in inverse ratio to her 
beam. The full text of the new rules, as officially pub- 
lished, is as follows: 
In pursuance of the vote of the Y. R. A. of M., creat- 
ing cabin classes for 21, 25 and 30ft. yachts, and in- 
structions to the executive committee to establish such 
limitations as would encourage the building of good 
cruising yachts in preference to racing machines, the 
committee have adopted the following limitations, real- 
izing that the open classes still exist for those who de- 
sire to build for speed alone. 
The committee have endeavored to frame such limita- 
tions as will encourage racing among yachtsmen who 
wish to race yachts in which all good qualities are not 
sacrificed for speed, and for the protection of the classes. 
Executive Committee. 
Boston, Dec. 15, 1898. 
Definition of Cabin Yacht. 
A cabin yacht is intended to be a seaworthy type of 
cruising and racing yacht, substantially constructed, prop- 
erly ballasted, and with moderate sail Rbin, either flush 
deck, or with cabin trunk on deck, having suitable cabin 
accommodations below, and conforming to the limitations 
herein mentioned. 
Freeboard. — The least freeboard, measured from the 
top of covering board to the surface of the water, shall 
be not less than as follows: 
Length .21ft. 25ft. 30ft. 35ft. 
Beam of or less than 7ft. 8ft. 10ft. 12ft. 
Freeboard, minimum . 21 in. 24m. 28in. 32m. 
Less iin. for every foot of additional L.W.L. beam. 
Cabin Trunk. — The height of the cabin trunk shall not 
exceed 2in. for every foot of greatest L.W.L. beam, 
measured from the level of top side of covering board 
to highest point of top side of cabin trunk. 
Cockpit.— The cockpit floor shall be above the L.W.L- 
with scuppers draining outboard. 
Cabin Floor. — The cabin floor shall be on timbers, in 
width not less than one-quarter the greatest L.W.L. 
beam, and in length not less than the following; 
Length ..21ft. 2§ft 30ft. 35ft.

wnder deck or cabin trunk beams, over the entire re- 
quired cabin floor, exclusive of skylights and hatches, 
shall be as follows:

ered. 
The keel, stem, frames, trunk and deck beams shall be 
of oak, or its equivalent in strength. 
A (stem). — The minimum siding (thickness) measured 
at the rabbet at highest point on stemhead, no decrease 
of siding allowed. 
B (sternpost). — Minimum siding at tuck (the crossing 
of the rabbet). The siding may diminish from tuck to 
heel. The rudder stock, if of wood, to be equal in diam- 
eter to the siding of post. 
C (keel). — Minimum depth allowed for middle. The 
minimum of sectional area (breadth multiplied by depth 
in the middle of keel) may be made up, if desired, by a 
deeper keel. The breadth of keel will taper from point 
of greatest section to siding of stem and sternpost. 
D (frames). — The sizes laid down in the table show 
the minimum sectional area of frames (the siding mul- 
tiplied by the moulding) at three points-Hhe heel of 
frame where it is boxed into the keel, the middle of 
frame about the flat of the floor and turn of bilge, and 
the head at planksheer. The sectional area is that of a 
single frame for a uniform spacing of ift. in each class. 
This required area may be made up of smaller frames 
spaced closer together, or larger frames further apart; 
or of combinations of large and small frames with ap- 
propriate spacings. This minimum sectional area shall 
apply to a space of at least two-thirds of the L.W.L. 
length in the center of the vessel; forward and aft of this 
the sectional area may be reduced 20 per cent. 
Two adjoining frames abreast each mast and one at 
each runnerplate should be increased in size in propor- 
tion as they are cut by the chainplate fastenings. 
Where bent frames are used in combination with sawn 
the bent frames may be of uniform scantling from end 
to end; but the sawn frames must be large enough to 
make up the required average sectional area at the heels 
where they are cut by the fastenings of floors. 
Spacing of Frames. — The maximum spacing of frames 
as given in the table is based not on the size of frames, 
this being variable, but on the thickness of planking 
allowed for the class; being the greatest spacing that 
will insure a tight seam with the usual caulking for the 
minimum thickness of planking allowed. 
E (floors). — There shall be at least six strong floors 
in the center of the vessel in way of the metal keel, and 
two at each mast step. 
F (shelf or clamp). — The minimum sectional area given 
for the middle shall cover a length of at least one-half of 
the shelf (or clamp) and in the middle, a taper being al- 
lowed to the size given at each end. The ends of deck 
beams may be jogged into top of shelf a distance not ex- 
ceeding one-third of their own depth. If a beam clamp 
is used, fitted close up to the planksheer, the beams being 
thus jogged in for their full depth, the sectional area shall 
be increased in proportion. 
G (bilge stringer). — The minimum sectional area at mid- 
dle shall cover at least one-half the full length of bilge 
stringer, with taper allowed at the ends. At least one 
bilge stringer must be run on each side, at about the 
lower part of turn of bilge. In yachts whose extreme 
beam exceeds twice the greatest depth from under side 
of deck to upper side of keel, .two such stringers on each 
side should always be fitted. 
H (deck beams). — The minimum section area of deck 
beams shall cover at least the middle third of the beam, 
allowing a taper, in the moulding, to each end. There 
must be one main beam at the bitts, two at each mast 
(partner beams), one at fore end of cabin trunk, one at 
after end, two at each skylight, hatch and companion 
in flush-decked vessels, and one at transom. The auxiliary 
beams and the half-beams abreast of house, skylights, etc., 
may be of the smaller areas given for each. The beams 
may be spaced at will, provided the maximum distance 
between centers does not exceed that given in the table, 
which is based, upon the thickness of deck planking. The 
beams should be jogged into the shelf of clamp a distance 
equal to one-third of the moulded depth of beam at ends. 
I (planking). — The dimensions given in the table are. 
the minimum thickness allowed, after final planing, over 
a distance in the middle of the vessel equal to at least one- 
half of the over-all length. 
J (decking). — The thickness given for the deck plank 
applies also to the planksheer (covering board) and the 
partner planks. The ends of the deck plank should be well 
supported, and in no case should they be wrought to a 
shim edge, which will crush down in caulking. 
Sail Area. — The sail area shall not exceed the product 
of the LW-L, length, multiplied by L.W.L. beam, multi- 
plied by 4V2, viz. : LxBx4>4.

To the actual *area of all sails allowed in Rule XL, fac- 
* Sailmaker's certificates of areas required and the actual number 
of square feet should be marked on all sails. 
ing rules, except headsails and spinnaker, shall be added 
the area of the forward triangle, measured as fellows: 
The forward triangle shall be one-half of the base, mul- 
tiplied by the perpendicular. 
The base line shall be the distance from a point on the 
forward side of the mast i8in. above the deck, to the 
point of attachment of the outer head sail to the bowsprit 
or stem. 
The perpendicular shall be the distance from the upper 
side of the sheaves of the uppermost halliard block on 
the mast to a point on the forward side of the mast i8in. 
above the deck. 
If any sail extends forward of the limits of this tri- 
angle, the excess shall be measured. 
Spinnaker Boom.— The distance from the outer end of 
the spinnaker boom to the rail, when in position for use, 
shall not exceed the L.W-L. length. 
Ballast —The amount of ballast, exclusive of weight in 
centerboard, shall be not less than the product of the 
square of the length minus the beam, multiplied by sisc 
times the L.W.L. length, divided by the beam, viz. : 
(I.-B)'X6-. 
Weights expressed in pounds.

Ballast, maximum required 3,500 5,000 7,000 
Ballast, minimum allowed 1,250 3,000 3,000 
All ballast must be below the floor of cabin or cockpit. 
Fixtures. — There shall be a substantial partition at the 
after end of cabin, and two permanent lockers, and suit- 
able berths or transoms for the accommodation of the 
crew. 
Fittings. — The cabin shall contain cushions or mattresses 
for the berths or transoms, and one blanket for each 
berth, or 7ft. length of transom, stove and cooking uten- 
sils, and receptable for two gallons of water. There shall 
also be on board anchor weighing not less than i^lbs, 
for every foot of L.W.L. length, and not less than one 
fathom of suitable cable for every foot of L.W.L. length, 
life preservers, compass, riding light, foghorn, bucket and 
boat hook. 
All fittings and fixtures herein mentioned shall be suit- 
able for cruising purposes, and shall not be removed, or 
substituted by articles smaller or of lighter weight. 
Existing Yachts. — Any yacht built prior to the adoption 
of these limitations, having smaller sail plan and less bal- 
last, or fails to meet the requirements on construction, 
freeboard, headroom, cabin trunk or floor or cockpit, 
may race in her former class, provided she complies sub- 
stantially with the intent of these limitations. 
Alterations made on existing yachts must conform to 
these limitations. 
Exceptions. — A yacht overrunning the limit of her class 
by not more than ift. may enter the class above provided 
she conforms to all the other limitations of the class for 
which she was built. 
Note. — "L.W.L." is measured with crew, racing truck, 
cruising equipment, etc., on board. 
Schooners and Yawls* 
Schooners and yawls to be entitled to the allowance 
for rig, mentioned in Rule VIII., racing rules, must con-i 
form to the following: 
A schooner shall not have mainmast forward of center 
of L.W.L., and foremast not forward of the point of im- 
mersion forward. 
A yawl shall not have mizenmast further aft from 
after point of immersion than 15 per cent, of the L.W.L. 
length, and mainmast not. forward of point of immersion 
forward. 
In cabin classes all limitations shall be based on actual 
dimensions.

Yacht Designing:* 
In spite of the favor with which the series of articles on 
practical designing was received by our readers, the pres- 
sure of much other work has prevented their resumption 
during "the past year, as was originally intended. We 
take pleasure now in announcing that they will begin 
again in the issue of next week, and will continue as regu- 
larly as the work will permit. It is the intention to issue 
them in book form after completion in the paper. The 
portion of the subject which will be first taken up re- 
lates to drafting instruments, their practical use, and the 
elements of marine drafting. 
YACHTING NEWS NOTES. 
The Marblehead Yacht Yard (W. B. Stearns) is al- 
ready busy with a number of yachts of various sizes. 
Com. H. C. Rouse, Seawanhaka C. Y. C, has ordered for 
himself and a friend, for use about Gloucester, two sloops 
of 25ft. l.w,l., 28ft. over all, 8ft. 6in. beam, 5ft. 6in. draft ; 
with 5,ooolbs. of lead on keel and 75osq. ft. of sail. The 
two will be exactly alike; they are intended for fast sail- 
ing and cruising. Messrs. Herman J. and Telford Groes- 
beck, of Cincinnati, have ordered two cruising yachts, 
each of 30ft. l.w.l., 44ft. over all, 12ft. 6in. beam, 5ft. draft 
of hull, with Tobin bronze board of 25olbs. housing below 
floor, the extreme draft being 9ft. The sail area will be 
i,30Qsq. ft., solely for cruising, and the lead keel will 
weigh i2,ooolbs. The yachts will be roomy and very ela- 
boratly finished. There is a wide floor in the cabin, with 
wing berths 27m. wide, the transoms extending to 3ft. 
Clothes lockers aft and a sideboard on each side for- 
ward will give space for the personal equipment of the 
owner. Copper tanks for fresh water are placed under 
the transoms, and on the port side forward is a roomy 
lavatory, with Bishop w. c, wash basin, pump, mirrors, 
linen lockers, etc. In the forecastle are berths for crew, 
large ice box, stove, lockers, etc. The cabin and lavatory 
are finished in mahogany in the natural color, without 
stain, but filled with five or six coats of varnish rubbed to 
a dead polish. Special bronze deck fittings will include 
an Enos Sheet Molder Company's winch forward and a 
winch for centerboard. The rig will be pole mast, with 
single jib. In the 21-footers is a boat for the handicap 
knockabout class, for the Cropley Bros., of Marblehead, a 
real fast cruiser, with accommodation for short cruises in 
a very attractive cabin. Two stock boats of this size are 
nearly finished, one similar to this one, and the other of 
the Cohasset type, with centerboard, but of more expen- 
sive finish than the one-design boats. 
The Forest and Stream is put to press each week on Tuesday, 
Correspondence intended for publication should reach us at the 
latest by Monday and as much earlier as practicable.
