The box is going to be made of 22mm mild steel with stringers that are out of 60mm plate which is to be drilled and tapped with 22mm holes. when the box is made up we will fill the voids with cement and lead.

The box will be held to the boat with 18 mild steel studs wrapped in ptfe tape and lithium based water pump grease

Total ballast weight will be 5000 kilos

We are in the middle of preparing the hull of the boat to put the covering of bi ax cloth and epoxy resin keep looking in for our up dates on this.
