The legendary Wally sailing yacht J ONE was hosted by RSB Rigging over the winter for a full standing rigging retrofit, changing out the old rod rigging and replacing it with Carbolink solid carbon rigging. Luxury yacht J ONE is a regular participant and a frequent winner in plenty of the most prominent regattas in the Mediterranean.
Refit of Wally Yacht J One
The refit of Wally yacht J ONE also included modifying the existing headstay adjustment system to include a custom made Harken hydraulic ram with a 150mm of stroke. This will allow the rig tune to be changed much easier as the conditions at the regattas dictates.
During the refit of superyacht J ONE, RSB in collaboration with Carbolink measured the whole rig with a laser in three different mast tune setups; light, medium and heavy wind. In each different configuration a reverse tune was performed and the rake and all the pre-bend measurements were taken at set points on the mast. Subsequently, the mast was un-stepped and the old rods were individually tensioned on the ground allowing each one to be check measured again. All the chain plates and tang interfaces were measured and the dimensions taken before all the details were sent to the Carbolink design office in Switzerland enabling them to start the cable drawings.

The spreader end modifications were performed by the Palma-based composite experts, Branagh Marine Composites. These involved cutting off the existing tip cup from the spreader end and splicing and laminating in a new designed super clean spreader end to accept the cable cleanly and with minimal windage.
The rig of J ONE yacht has been recently re-stepped, is now dock tuned and the sailing trials have been completed. Next week along with the race crew RSB will perform the last fine tuning of the mast with the new sails. RSB Rigging’s Russ Brown states: “Having taken 200kg out of the mast by replacing the old rod with the Carbolink carbon product the boat now feels quite different. The work now begins on updating the on-board Polar and VPP information and modifying the target boat speeds and angles. There is a lot of testing and learning to be done before the Palma Vela regatta at the end of April. We are sure that the improvements will make the boat quicker and enable us to remain competitive in the upcoming regattas.”
