Hi Clive,

Well, at least the two C's have a use a the moment, so a watching brief on them perhaps. Regards Ryde she is still in with a chance, local guys are working to save her, she is not in the best of nick but was very well built and so has a good chance but is very touch and go. In comparision to MQ, perhaps worse in that she was dumped outside the mill pond and although floated once a year for a while, was full of mud and .....when we got her. As you will see from the web-site, www.medwayqueen.co.uk, we have now dismantled her to her component parts ready for the new hull, when it starts, costs, well, we spent 280,000 on the dismantling, which we had of course saved/raised, and over the years some 200,000 in preservation costs, we have some 100,000 in the bank, but a lot more to raise in partnership funding for the lottery grant pluse the final fit out!. The money spent on the dismantling will count as partnership funding though. Hope this was of interest,

Thanks for the insight John, the money involved is amazing but she will be a fine vessel when complete, I have breathed in so many times regarding costs involved with '32 I am waiting for my trousers to burst!

No problem Clive, we all await 32 coming out and she will be a great site out and about, do say if you get down south and we can arrange something her at Chatham.

Hello All. I would like to throw in my five pen'th into this discusion.
As it involves two boats. I will begin with The dogboat.towards the end of the war I had a passion for this vessel assuming it was the be all and end all to all war time craft. I have made many models of this craft Half models Desk models and working models. In 1946 one came into my home prt of Goole a gift though on loan I was a sea scout. The vessel'snumber was 741 but it was named Honeysuckle after the corvette which my home town bought for the War effort. After ending my apprenticeship I joined the RAF marine division . I still had a love for this vessel. but then went through a phase where I once thought myself as a traitor. For reading about the chine boats versus the displacement boats made me wonder. Which in fact was the better boat during the war?There is no doubt that the chine boats ,also their crews suffered badly in heavy seas. Whereas the E boat was as one with the sea.It was in my opinion the ultimate vessel.
What puzzles me is when I have spoken to designers of power craft (I have met many)I have put forward this question, Why was the Eboat such a great success. They on the whole come up with the same answer "Horse power."  This is not true. For I believe the Lursen Efekt adjustable wing rudders been the true answer. He found by placing the wing rudders directly behind the prop Then at speed angling both rudders at 30 degrees outwards. It would serve two purposes. One (as no doubt most readers will know) It brought the bow down and the ship would run level. Not only that but"solid"water would be directed on the prop. Giving a better bite. Over the years I have made a study of this and found not one commercial designer use this method. but stick steadfastly to chine boats. most of which you will see every day badly trimmed and not running level
Regarding building form new one of these vessels Modern day practice of composite ship building has been to use a foam core with Kevlar outer skin and an inner skin of carbon fibre. Then under controlled conditions(usually in a oven ) time allowed for the resins to cure. This type I have knowledge of but although desingned by one of the best designers and it came out of the mould way below design weight It was a disaster.
So my feelings on replica work would be to build it as the original was built.
I did know of a replica Eboat which visited our waters in the mid 80's Built of steel. Slightly diferent profile above the WL but the same lines below and three 20 cyl Mercedec plus the Lurson efekt rudders

Hi Bill,
 
Planned to post eleswhere on HSL 145 and will, but saw you last on this subject, went a bit quiet for a while there! very interesting your comments, just heard from the group doing S130, hope to have an update on there web-site soon apparently. I have to confess myself still thinking on about replicas and re-builds of the D, just thoughts which of course are very cheap! I always acknowledge the existing craft we do have, MTB 102, HDML Medusa etc....and am involved in other projects so tied up for the moment.....but thanks again,
