Neat .. permission to board captain. My late cousin Athol Burns had an interest also in ferrocement ocean going yotts .. he & my father used to tinker in Wellngton when they had their boat building shed at Ballena Bay before moving up to Northland. I will add yr pix to my growing album of home-built yotts & as an extension to thep pix of Athol's .. many of which are still at sea & afloat ... Have a day or two at sea ..
