Been on the market for a longish time, was £145k I think, now approaching a sensible starting point for haggling.Oddly I went on a local boat trip and we embarked from the pontoon adjacent to this, so I had a good look at her from the exterior and thought it could do with a bit of finishing really.
She is striking and certainly catches the eye, however I'm all about practicality on the water and like big open cockpits, in these boats you are so divorced from your surroundings whilst underway and its only really suited for people who like to spend all their time below decks.

There are no anti-siphon valves on the head piping.
Its a lavac.Not familiar with Lavac, but if you don´t close the seacocks, what stops the water siphoning back into the bowl?

Explain? Looks like the small pipe is the seawater in, and the larger one waste out. A diaphragm pump. Two loops with no siphon break.

When you've finished your business you lower the lid on the pan, there's a rubber seal around the lid.Not familiar with Lavac, but if you don´t close the seacocks, what stops the water siphoning back into the bowl?
Operate the big pump on the bulkhead, its connected to the outlet at the bottom of the pan, creates a vacuum which draws the flushing water in through the little pipe.
Hence one single pump pulling water straight through, v simple.
If you had a big loop with a anti syphone valve in the top it'd let air in, to break the syphon, but would also prevent the vacuum so the flushing wouldn't work.
Plus on motorboats that don't heel over its quite common to find no anti syphon valve.

As a total non boaty person, 3X turbo diesels and 15 knots = no thanks.
3 x 2,000hp supercharged V20 MB501 diesels and 50 knots is much more to my likening.Shame only a single example of a Schnellboot exists today, so looking forward to the completion of the restoration of the Wheatcroft Collection's S-130

Never had anything to do with those.The motor boat ones I work on have a printed circuit board in the back and micro switches, besides the separate clunky clunk vacuum pump! Bloody ridiculously complicated way way to go about taking something as natural as a dump!
I´ve got a nice new mini Jabsco to go into my little jigger

Not if they're going to leave out the anti-siphon valve...

Did E-boats really do 50kts?
Yup. They had longer range than either our MTB's or the USN PT boats as well, and were better in open seas too.When I was a kid/teenager, our next door neighbour was an ex-MTB crewman, he spent most of the war out in the med on the RN MTB fleet. At wars end they were deployed to Norway, and he was one of the crews that got to play with some surrended S-Boot's. He said they were excellent craft. It's listening to his stories back is the reason that I've always had a particular interest in S-Boot/MTB/PT ops.
I also remember he had a photo of him standing on the capsized hull of the Tirpitz

One of those small private yachts that go under, and don´t come up... She is nice though, but there´s now nice low cockpit to sit and drink beer while you fish. Still she´s wood, so a chainsaw could sort that in next to no time

Is that still making progress? No updates on the web for a long time.
I knew about it via word of mouth from a few years back, via people that had connections with them via their other mil vehicles projects, but have been a bit out of the loop in that respect for a few years, so not sure what is the current state of any of the military aspects of the collection thesedays.
