Improvements in Yachts.
1, WALTER SCOTT WINANS, of 15-Brechin Place, South Kensington, in the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
According to this invention the sides of the keel are made to slope outwards so
that the keel is broader at the bottom than at the top so that when the vessel is
heeled the keel presents a perpendicular, or nearly a perpendicular surface to the
water, and is thereby much more effective in preventing leeway, and also from its
greater width at the bottom enabling the ballast of the keel to be placed much
Tower down and thereby with the same weight of ballast giving considerably more
stability to the vessel.
is on.
In applying centre-boards to keels such as are described above I employ two,
one on each side, one or other of which is lowered according to the tack the yacht
These centre-boards are inclined at the same or a greater angle than the
angle of the keel, so as to present a perpendicular, or nearly perpendicular surface
to the water when sailing on either tack, and are thereby much more effective in
preventing leeway. I connect these two centre boards together with a chain or
wire rope over a pulley so that in raising one board up and lowering the other as
the vessel goes on the starboard or port tack, the friction only of the boards in
so doing will have to be overcome as one centre-board will balance the weight of
the other.

I, WALTER SCOTT WINANS, of 15 Brechin Place, South Kensington, in the
County of Middlesex, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
According to this invention the sides of the keel are made to slope outwards
so that the keel is broader at the bottom than at the top so that when the vessel
is heeled the keel presents a perpendicular, or nearly a perpendicular surface to
the water, and is thereby much more effective in preventing leeway, and also from
its greater width at the bottom enabling the ballast of the keel to be placed much
lower down and thereby with the same weight of ballast giving considerably more
stability to the vessel.
In applying centre-boards to keels such as are described above I employ two,
one on each side, one or other of which is lowered according to the tack the yacht

wire rope over a pulley so that in raising one board up and lowering the other as
the vessel goes on the starboard or port tack, the friction only of the boards in
so doing will have to be overcome as one centre-board will balance the weight of

Figure 1 is a side elevation of a yacht constructed according to this invention
the cover of the recess in which the centre-board lies being removed. Figures 2
and 3 are trausverse sections.
a is the keel, b the ballast, cc the centre-boards pivotted at c¹ to the keel and
connected together by the chain d passing over the pulley e.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is :-
1. A yacht having the sides of its keel sloping outwards substantially as
described.
2. The combination of a keel with its sides sloping outwards and a pair of
centre-boards one on each side substantially as described.
3. Yachts substantially as described and shown in the drawings.
