Caution; I used Chris to survey the hull of a 45ft catamaran I subsequently purchased sight unseen from NZ. Be wary of this guy, he classed my rudders and keels as good condition. The keels were full of water and diesel and delaminated on the bottom and the port rudder also had bad water ingress and severe corrosion on the post. 15k NZD + to remedy. Cut keels off, cut tops of diesel tanks out for access, grind most of rudder away. Huge jobs he could have warned me about if he had done his job
