Interested how you get on. There's build info and pics back to the original article on Google. 2 were pictured by someone here on the new carrier sea trials entering harbour.
I have a hull but made a bad start so far. Also I thought I bought 555 motors but think they might be the rubbish 550's in the end. Unfortunately for the original designer, pics of the plans are on-line enough to make a start and check allot of crude dimensions. Personally I think the hull is out at the transom. Think my moulding is "v" shaped when it should be curved across the beam? I have a feeling the beam is out a bit also, but that could be usual "spring back" after vac moulding.
Not sure if that helps,
