The Lürssens boats were an excellent design. They weren't faster than the Thornycroft CMBs of WWI, but were better sea boats, even at speed. Max speed of this class was 38.5 knots from 7500hp, so the article quoting 55 knots is nonsense. Most of the Italian MAS boats and many others were faster than the S-boats, but not as long range or as good sea-keepers, nor were the MTBs and MGBs of the Royal Navy. The Soviet G5 class torpedo boats got up to 55 knots. S-130 was one of 35 S-boats surrendered to the British in 1945, she served with the RN as FPB 5130. 261 S-boats were in service in WWII.
The new owner says he wants to get a Kalotte armoured bridge from one of the S-boots sunk off Denmark; hopefully he won't try and retrofit it the S-130 which never had one.
