Details

A robust ball raced gooseneck/kicking strap unit for use with 16.5 mm dia mast tube and suitable for A Class or similar large boats. The carbon/epoxy body of the gooseneck fits snugly onto a mast with 16.5 mm diameter and ensures a secure and perfectly aligned fit for this key item of the boat's rig.

Designed to be used with a main boom made of 14 mm carbon tube reinforced over the forward 250 mm with 12 mm carbon tube. The boom end fitting is cranked to allow the use of the 25 mm foot roach permitted by the class rules. The wire kicking strap is 1.8 mm dia rod. The compression strut is self-locking and is provided with the 27D welded steel plate for attachment to the boom.

Axis alignment

The design of the gooseneck body ensures it is aligned with the mast perfectly. If the effect of a tilted axis gooseneck is required (also known as adjustable axis gooseneck, variable axis gooseneck) then it is a simple matter to place a packer of the required thickness under one end of the gooseneck body before it is fixed to the mast tube. Use deck patch material or other self-adhesive material to achieve this. 1.4 mm thickness will tilt the axis by 1 degree. One layer of SAILSetc deck patch material will tilt the axis by 0.07 degree.

Maintenance of the bearings used in this product is described here.

Gooseneck is the English language term for the attachment between boom and mast. Other words used are boom pivot and boom swivel.

Kicking strap is the English language term used for the adjustable connection between the lower end of the gooseneck and the boom. It is also known as a vang.
