Home built catamaran sailboat. Centerboard through cockpit working well

Tangaroa Mk4 35' catamaran sailing close hauled on the the Hawkesbury river with the new 3m centerboard for the first time. The boat now sails to windward and goes about when tacking with ease. The centerboard balances the helm so well I am able to walk around taking this video without the need to steer. This boat was bought as a an unfinished project for $500 with lots of rot. Prevention of further rot is on going with epoxy resin and fiberglass. This is the drawback of timber. The mast and rigging cost over $7000 and new mainsail $1400. Other sails were taken from my sail trading business (Second Sail) which has kept the project cost under control.
