Rob, wish I could be there, look forward with interest to the results. In
particular- cost, time, finish. Will the shape of the boat have to change?
I'll expect a full report.
I'm always impressed when a kiwi male can say he was wrong, something I don't
have to do, my wife takes care of it for me.

What has changed my mind? A bunch of things: Working with the flat panels,
the advantages of infusion, getting away from the all rounded look of Harrys
(a flat deck is required on the solo boat to attach the beams to), the need
for a better finish than I found acceptable and the cost of fairing and
painting Rare Bird.

But mostly, it was the realisation that I was wrong.

Since I made those comments, I have had a few emails to and from Derek.
Apart from him being a nice guy, I found it impossible to discount his
experience in the business, his successes and his enthusiasm. I enjoy
learning from people who know more than I do (particularly unpretentious
ones) and expect to have a great time with the new technique.



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
