18ft Skiff Victory

By All News, Marine News

CST 18ft Skiff Wins San Fran

After a short development period Howie Hamlin and his crew steered the “CST Composites” 18ft skiff to victory in San Fransisco.

In the lead up to the JJ Giltnan and the San Fran Regatta, the CST engineering team developed new mandrels and products to provide Howie and his team with the winning platform they were looking for.

Archie massey, Dan Wilsdon and Mike McKensey will also be joining the CST team, putting together a strong 18ft campaign off the back of their I14 World Title victory.

Archie and his team will have the latest CST rigs from the “ELITE” series. This incorporates a number of innovative ideas that developed from the I14, providing them with the stiffest rigs in the fleet.

Three Times I14 World Champions

THREE IN A ROW FOR CST

CST is proud to congratulate Archie Massy and Dan Wilsdon who have won the 2011 Artemis I14 World Titles recently held in Weymouth Bay.

Constant mast development has resulted in three back to back wins in this class for CST.

We aim to transfer our expertise and advances to the 16ft skiff class and hope to continue our successes into the future.

Final Sign-off for Production

By All News, Marine News

A number of sailors looked on today while the new carbon mast was measured for final luff rounds.

Sails will be complete next week and hit the water shortly after.

With a number of masts on backorder, production will now be full steam ahead.

Pricing for 16 Masts

Pricing has been set for the one piece 16′ Skiff masts.

Two masts are currently being fully rigged.

We can currently supply four fully rigged masts per week.

FEA and Mast Design

By All News, Marine News

The first part of the process is to come up with an overall rig layout within the rules.  This will assist determining the overall mandrel geometry.

Choosing a one piece mast with no sleeving means that specific patching will be incorporated into the laminate for high load areas, reducing hard points and stress raisers.

 

Pattern design

We then generate a stiffness profile to suit the mandrel geoetry and mast layout.

Pattern design, optimises the laminate thickness vs stiffness vs toughness.

Patterns go direct from engineering to production floor winding machines, minimising human error.

FEA

With FEA models built to replicate the laminate schedule,  a number of “What if” scenerios can be run to determine various bend profiles.

This provides sailmakers and sailors with an option to choose their preferred stiffness as well as bend characteristics.

Model Vs Actual

Final step in the first article is to confirm actual results vs modelling.

With over 25,000 tubes made, the model predicts the bends within +-1%

Quality control reports show that the bend profiles of all masts are repeatable within +-2%

 

 

Rigged mast will be in the boat next week !
