Quick update on slow boat build got most of the ballast down still 3 bays each side to do at the stern end still bit worrying about the weights thou once it’s all done . Each brick weighs 3.5 kilos and once complete there will be 500 bricks installed on my calculations 1.750 kilograms wich is 1.9 tons and it was worked out the boat needed between 1&1/2 to 2 tons. So I’m thinking only way to go is lay flooring and do sides and ceiling finish off all the outside then have to move it to a marina before fitout so can remove or add ballast as needed
