Great films. Men standing out on the ends of bowsprits, standing on deck, boats sailing heeled over at a great speed, no guard rails, jackstays or lifelines and not a lifejacket in sight.
Obviously there was a different attitude towards health and safety.
Double clewed jib.
A headsail which was also known as a quadrilateral jib. It was introduced aboard the J-class Endeavour by her owner Mr (later Sir) Thomas Sopwith prior to the 1934 challenge for the America's Cup. It was really an extra-large jib with the clew cut off to form a four-sided sail sheeted with two sheets, with the new fourth side corresponding to the leech of a normal four-sided mainsail on a gaff rig. It was almost certainly the invention of John Nicholson, the son of yacht designer Charles E. Nicholson, who designed Endeavour and whose firm, Camper & Nicholsons, built her. It was believed by the British to be more efficient than the normal triangular jib. It was known to the Americans, who quickly adopted it, as a ‘Greta Garbo’, but it never caught on as a racing sail.
A double-clewed jib is a type of jib sail used on some sailing vessels, typically in the context of multi-hull boats (like catamarans) or certain types of traditional boats. The term "double-clewed" refers to the sail having two clew points, or attachment points, for the sail’s aft corners.
In a typical jib, there is one clew, which is the aft lower corner of the sail, where the sheet (the line controlling the sail's angle) is attached. In a double-clewed jib, there are two clews, often positioned on either side of the sail’s lower edge. This arrangement allows for more flexibility in adjusting the sail’s shape and improving performance in certain wind conditions.
Benefits of a Double-Clewed Jib:
Increased control: Having two clews can allow for better control over the sail's trim and shape, which can be useful when sailing in varying wind conditions.
Improved performance: This type of jib can be more efficient in certain types of downwind or reaching conditions, allowing the boat to sail faster.
Symmetry: In multi-hull boats, a double-clewed jib can help maintain balance between the two hulls, especially if the boat is set up with a jib on each side.
The double-clewed jib is not as commonly used on single-hull vessels but is more often seen on specialized boats, especially in racing or performance cruising. It’s worth noting that rigging and handling can be more complex due to the dual clews, requiring careful attention to both sheets and trimming.
