Rig development

[David Hudson]

I started this post in Gennakers etc. but I have decided to transfer to a new thread.

I am yet to see the maths regarding mast loadings and gennakers but I wonder whether certain “givens” about our masts and rigging still stand. My maths speciality is financial investment not mechanics, so the numbers may pass me by.

When Dudley Dix designed the Cutter, a different spec. of spar was stepped. I gather the original was lighter and had a larger longitudinal void: (that would be useful now). Perhaps that is why the original Cutter design did not have a gennaker included in its sail inventory. Perhaps it was not part of Dudley's design vision.

As to limitations in the rig, it's good to talk. Discussion would lead to design development, increased functionality and seaworthiness of our Cutters. Bob has already incorporated various owners’ experiences in the new Cutters and I am sure Dudley would welcome properly considered development of his rig design. I’m not suggesting modification of the hull but the recognition of the progress in rig and fittings such as dyneema rigging or the introduction carbon masts and bowsprits. The essential is that the Cutter maintains Dudley’s vision.

I wanted to fit a wind indicator and use ascendeurs to climb the mast. In past days I would have shinned up. We are advised to drop the mast. Is there a fundamental problem with the standing or running rigging? There are no details of safe working loads readily available for the South African blocks fitted on the Cutter. We don't sail exclusively on lakes, as I am doing now. The North Sea or the Hebrides are a different matter. Conditions can change in short order. What happens at sea if you want to set a jury rig after a masthead fitting or halyard parts?

Remember both Bob and Mike;“the seahorses’ mouths;” gave me photographs and discussed the Gennaker project with me and Mount Olympus is too far off.

Never mind, I've fitted running back stays, mimicking the fourteen foot fitted dinghies that we sailed in Bermuda in the 70's. 1000 s quare feet of sail no sweat! I may even publish photographs .

Let’s talk experiences. Perhaps we might consider a meeting each year at the Boat Show to discuss matters of common interest and drink Guinness during the breaks.

So far I have drawn on the experience of at least six Cutter owners while fitting out Tokoloshe. Thank you all.
