Abstract
A spinnaker header and rig adapted to high performance racing sailboats for adjusting the height from which the spinnaker is flown, characterized by gear adjustable as to height along the forestay under control of a halyard and downhaul, and by a backhaul to take the driving force of the spinnaker.
Claims30
A spinnaker header for supporting a spinnaker sail and adjustable as to height along a forestay extending to a mast projecting aloft from a sailboat hull, and including;
- centering means guiding the header along the forestay, spinnaker coupling means securing the head of the spinnaker to the header and receiving the pulling force from said spinnaker, halyard coupling means securing a halyard line to the header to raise the header, downhaul coupling means securing a downhaul line to the header to lower the header, the said halyard line and said downhaul line cooperating to position the said header as to height along the forestay, and a backhaul coupling means securing the header to the boat hull to transfer pulling force from the header to said hull.
Spinnaker header hardware for supporting a spinnaker sail and adjustable as to height along a forestay extending to a mast projecting aloft from a sailboat hull, and including;
- a centering trolley means guiding the header along the forestay and confined thereto by a frame journaled to the trolley means by a bearing pin, spinnaker coupling means pivoted from the bearing pin by said frame and securing the head of said spinnaker to the trolley means to receive pulling force of said spinnaker, halyard coupling means pivoted from the bearing pin and securing a halyard line to the trolley means to raise the header, downhaul coupling means pivoted from the bearing pin securing a downhaul line to the trolley means to lower the header, the said halyard line and said downhaul line cooperating to position the said header as to height along the forestay, and a backhaul means pivoted from the bearing pin and securing the trolley means to the boat hull to transfer pulling force from the header to said hull.
Spinnaker header software for supporting a spinnaker sail and adjustable as to height along a forestay extending to a mast projecting aloft from a sailboat hull, and including;
- a centering saddle means guiding the header along the forestay and combined with a backhaul having coupling means securing the header to the boat hull, spinnaker coupling means securing the head of the spinnaker to the header and receiving the pulling force of said spinnaker, halyard coupling means securing a halyard line to the header to raise the header, and downhaul coupling means securing a downhaul line to the header to lower the header, the said halyard line and said downhaul line cooperating to position the said header as to height while the said backhaul transfers said pulling force of the spinnaker head from the header to the boat hull.
