Thanks Chris for the explanation. As someone who has never built anything quite so large I’m interested in the logistics that go into it. Your magnificent builds demonstrate a system that very much works so no need to change whatsoever! It does raise another question though (and i might be jumping the gun here) but you must have a system for joining the 2 halves so that they’re water tight? You may have explained this in the Norfolk build so I hope I’m not retracing old ground.
