Hi Herb,
Yes I did say that and that is how I understood the process. Since then I have been experimenting, both on the computer and in the workshop, with various ways to get a good hull shape using as much flat panel as possible so we could laminate most of the hull on a flat table.
As my experiments progressed and I learnt more I realised the logical end to it all has already been discovered. This is the process that Derek has been working with for years and now virtually perfected, KSS.
I have never attended a KSS workshops so know as much about it as anyone who has seen his website and magazine articles. Seeing some of his latest hulls and workshop results had me impressed enough to suggest to Rob we invite Derek over to Australia so we can see for ourselves. We are just about to start Rob's 50' Transpac racer using flat panels so it was a perfect opportunity to organise a workshop and share the knowledge with anyone else interested.
Hope you can make it.
Mark Stephens

Dear Rob,

Very interesting and welcome news.

In the past you have generally said that there wasn't much difference
in building time and effort between strip plank and KSS. What has
changed your mind?

Also, in a post a few months ago Mark said that KSS required a lot of
darts and bogging. Is this true or have you figured a way around it?

Best regards

bogging and sanding strips of wood or foam in the traditional strip
plank method, or any of the heat it, bend it and screw it foam techniques.

of the deal, Derek is putting on a 4 day workshop at our factory in
Urunga (midway between Brisbane and Sydney, 20 minutes south of Coff's
Harbour) to demonstrate how infusion and KSS work. He reckons that at
the end of it, we will have the hull ready to top coat paint, and a
15m vacuum table. It would take more than 4 days to fill and fair
the hull of a 15m strip planked boat, so this will be a very
impressive achievement.

Anybody who wants to attend is welcome, at a cost of $500 for the 4
days. This includes lunch, morning and afternoon tea, the chance to
participate in the build and to pick Derek's brain on the technique.
Mostly though it gives you a way to save a huge amount of time
building your own boat. Local low cost accommodation is being
