ABSTRACT:
The present invention provides a shock absorber unit for use on sailboards to absorb detrimental vertical forces generated during sailing in rough water. The unit replaces existing flexible solid rubber universal joints with a joint comprising a pressurized chamber with a flexible side wall. The flexibility of the side wall allows the present invention to absorb the impact forces while serving as an improved universal joint.
