Bulkheads are 3/8 ply all cut out with a jigsaw!
I had half a sheet of it laying around so got the keel and the bulkheads out of it
I bought the plans on ebay from Davesdrydock who has a online store on ebay
The plans are ok for the money but are not brilliant, but for a base and getting started they are perfect....cheap too!!
Pressure mounts now to make this model look good as i suddenly realise people are actually watching!!
here is a link to the ebay store for plans
