Abstract
A twin wing sailing yacht having a pair of wing appendages depending from a canoe or hull, the wing appendages including structures which support at their lower ends a fore and aft extending ballast tandemly suspended between them. The wings are rotatable about generally vertical axes under the control of collective and cyclic steering mechanisms.
Claims33
A twin wing yacht comprising:
- a canoe;
- a ballast body;
- a front wing extending generally downwardly from said canoe and having a lower end;
- a rear wing extending generally downwardly from said canoe and having a lower end;
- means associated with said front and rear wings for structurally supporting said ballast body from and between said lower ends of said wings;
- said front wing having at least a rearward portion thereof articulated about a generally downwardly extending axis to form a first, front moveable control element;
- said rear wing having at least a rearward portion thereof articulated about a generally downwardly extending axis to form a second, rear moveable control element;
- means connected to said front and rear control elements for cyclic turning thereof;
- and
- means connected to said front and rear control elements for collective turning thereof.

- a ballast body;
- a front wing extending generally downwardly from said canoe and having a lower end;
- a rear wing extending generally downwardly from said canoe and having a lower end;
- structural member means included within each of said wings for supporting said ballast from said canoe;

5 more elements
A twin wing yacht comprising:
- a canoe;
- a front wing depending from said canoe;
- a rear wing depending from said canoe;
- a ballast body mounted from and between the lower ends of said wings;
- each of said wings including at least portions thereof forming control elements articulated thereon about generally downwardly extending axes;
- control means including independently operable collective and cyclic control means,
- said collective control means serving to move said wings simultaneously in the same angular direction without opposite angular motion while said cyclic control remains neutral;
- said cyclic control means serving to move said wings in opposite angular directions without angular motion in the same direction while the collective control remains neutral;
- said cyclic and collective control means being also moveable simultaneously in which case the net angular motion of said wings responds in proportion to the relative motion of the cyclic and collective controls.
6 more elements
A twin wing yacht comprising:
- a canoe;
- a ballast body;
- a front wing extending generally downwardly from said canoe and having a lower end;
- a rear wing extending generally downwardly from said canoe and having a lower end;
- means for mounting said ballast body between the lower ends of said wings;
- said front wing having at least a rearward portion thereof articulated about a generally vertical axis to form a first, front moveable control element;
- said rear wing having at least a rearward portion thereof articulated about a generally vertical axis to form a second, rear moveable control element;
- each of said front and rear wings defines a root portion connected to said canoe, and further in which
- said wings defining therebetween an essentially free space so that said wings collectively form the principal side force appendages of said yacht;
- said canoe being constructed and arranged to move with a hydrodynamic surface wave structure attached to and traveling with the canoe, below which surface wave said canoe's displacement supports the principal weight of the yacht, with said displacement generating a wave trough adjacent the middle of said canoe on the windward side when sailing upwind, and in that the fore and aft position of said front and rear wings are forward and rearward of the principal surface depression of said trough, respectively.
7 more elements
A sailboat comprising:
- a canoe;
- a front wing depending from said canoe;
- a rear wing depending from said canoe;
- an elongated ballast body supported adjacent its front and rear ends by and between lower ends of said wings;
- said front wing having a forward portion rigidly attached to said canoe with a rounded leading edge extending downwardly from said canoe towards said ballast body;
- a cusped aft end with rearwardly facing right and left lips extending downwardly from the canoe towards said ballast body;
- and right and left surfaces between said lips and said leading edge defining, in part, an airfoil section in a plane approximately perpendicular to said lips;
- and
- said front wing further having a rear flap articulated on said forward portion with said rear flap having a forward edge extending downwardly from said canoe towards said ballast body with said forward edge housed inside said cusped aft end, and a trailing edge extending from said canoe towards said ballast body,
- and a thickness contiguous said lips substantially equal to the distance between said lips with port and starboard surfaces of said rear flap extending rearwardly from said forward edge to said trailing edge defining, in a plane perpendicular of said rear flap, a cross-section of airfoil shape.
