I just think it's peronal choice really, and as times go on, people like to own the latest gagetry and modern stuff........I myself love the old classic double ender boats pre fast afloat boats, the woodwork and mystique of them really gets to me, but if I were to build a modern fast afloat boat my two choices would be another model of 52-02 the second prototype Arun Sir William Arnold or a Tyne............there is no finer boat than a Tyne in my mind, and the sound of their Detroit V8 two stroke Diesels are something that I could bottle and sell for posterity.....just beautiful boats.
But each modeller has their reason for choice and the more choice the better in my mind.
as to your question about the hulls, I simply don't know apart from the fact that when I built my Arun model of 52-02 I had to change slightly the partial tunnels at the stern to make them a little more pronounced and changed the spray rail at the bow to a more pronounced curve towards the stem peak.
But that was all...haven't got a clue about the Tyne as haven't built a lifeboat model of one from the grp hull available.However I did build a concept boat from MBD hull and superstructure where I had to extend both superstructure cabins as the Hon sec of Fleetood RNLI station wanted to convert a real Tyne into a private "yacht" concept to promote the RNLI, and I saw nothing untoward with the hull when I made that, but it was a simple mock up that I made, and nothing more than that and definitely not a scale model..
