Given Glyn and Ben are Project Managing and Team Leading, respectively, the simultaneous build of two very different Catalysts, they have been making excellent progress.
In the last newsletter, we left B73 having just had her hull turned over with bulkhead and systems fit-out underway. Well, a lot has happened since then and as the saying goes, a picture paints a thousand words – so here are a few pictures rather than a few thousand words.
