Ouch, kevlar and carbon are restricted materials within the tornado class. Sorry..

I dont think strip planking is a good way to build a Tornado. You will get to many horizontal glue joints that adds a lot of weight. At least that was what Farrier discovered when he started to use vertical joints between foam sheets.

I really liked the Gougeon system used as internal stiffening. Building out of plywood is easy, but I'm afraid the panel stiffness would not be very good.. Perhaps the Taipan builders can correct med ?

If plywood boats was good, why did the Gougeons use cold moulding ?

I looked into how to get the hull lines for the Tornado, and found some interresting things.
1: Measurement of the hulls are very detailed, not much room for error if home building/designing.
2: Measurement blanks costs £ 800 !!! (I know where I can source som old ones for free, but..)
3: Marstrøm, Yves Louday/Reg White are launching new models with new hull shapes. Basically they have made the hulls slimmer in front and less bouyant at the stern.
