I once had a very obscure fault that gave similar symptoms so it might not be your problem.
.............................................however...................................................
On one boat I had there was a fault that showed up as a lack of power at high rev's when reversing, it didn't seem to be any worse at low/med revs but soon as you started to go full astern there was no apparent increase in power. it gradually got worse and there then was a noticeable delay before the ahead power became available when changing from astern to ahead.
The fault was a sheared woodruff key on the prop.
When going astern the prop was slackening slightly on the taper and slipping on the shaft, it only being noticeable at higher revs as at slower speeds there was enough friction for it to still "drive". When you then went ahead the thrust from the prop drove it back onto the taper.
It was only when the wear increased that It became noticeable enough for me to work out what was happening.

It costs very little to add at the design stage so my view would be stick the cables in ....... you don't have to use them. If you don't put them in they will be a proper buxxer to put in as a retro fit.

That looks like a pretty serious trailer.

I've yet to read a proper technical explanation that I've actually understood and agreed with as to why current flowing through the boat's hull matters one jot. Most explanations revolve around anecdotes, or the 'best not do it, just in case' train of thought when rendered down, IIRC.
If you have multiple earthing points to the hull, if you lose a major negative feed, for instance your engine earth strap, for any reason ( loose connection for example)
when you try and start your engine you could get a few hundred amps attempt to go through an alternative path i.e. your solar panels

I'm not too certain but I thought they stopped very early in the 90's maybe 91 ? seem to remember reading an old thread about it and 1990 seems to have stuck in my head
got it http://www.canalworld.net/forums/index.php?showtopic=32395

You could fit a standard manual pump Jabsco sea toilet and plumb it to the holding tank, the pump has the action of breaking up solids and they are very cheap to buy and service, they will use sea or canal water so don't deplete the potable supply. This arrangement is present on many sea boats including my own and works perfectly well.
that solves the first part of the problem ......... but not the emptying of the tank ........ there must be another way

that's getting better Wolly' it must have been the big difference in angle between the front of the cabin and the screen that made it look so odd. As you say when you trim the wood to allow for the rake of the cabin top, it should come spot on in line ! Good result mate !

The suspect appeared in court today and gave his name as "death to traitors, freedom for Britain". He is a political extremist who killed a political enemy for political reasons. "Bring politics into it"?
I cannot make my mind up if you are making posts like this due to pure insensitivity or if you are trying to provoke a backlash from political opponents for your own gain.
Whichever it is, it is the wrong time and place to do it .... as you are well aware.

they sound like swaged captive nuts, very useful with thin metal assemblies, we used them a lot for fixings on chassis for electronic equipment

That's a shame Wolly, everything else looks so right and that just looks so wrong. As you say projects go like that sometimes.
Take it off, have a sit and a cider, then look at it fresh.

The A&C is a lovely run, I did it in Shapfell which is a 25' narrow beam cruiser. You do feel somewhat dwarfed in the huge locks, bu it;s all very easy.

A word of warning,
When I was looking at systems for Sabina H, I considered Vacuflush.
A marine engineer (whose views I trust implicitly with anything to do with ships or boats) advised me to stay away from them under all circumstances.
He told me that the Vacuflush system was fitted to several of the Thames river cruisers and Party boats and used to cause more trips to the repair yard than any other system on board.
This was a long time ago, of course but I strongly advise you talk to owners of the system you are thinking of ..... preferably several of them.

I suspect if you look at a selection of GRP boats from the same period they will all show some signs of what would now be considered poor workmanship.
there is never an excuse for a shoddy job

yet another post worthy of a greeny !
Your posts and W+T's are two of the main threads that keep me returning to this site !

no need to SHOUT. - oh and it should read "It boggles my brain when trying to read this"
Yeah ! You tell em, blumin' grammer hamster ...... where's Freddy Star when you need him

I'm going to ask you a question that you avoided answering the last time I asked you it.
As we now have Naughty-Cal out of the water for three months each winter we only licence her for 9 months of the year with a 3 month period unlicensed whilst ashore.
When we apply for our next licence after the period ashore CRT make it very clear in the email and letter they issue that the licence is temporary until they investigate the lapse in licence period.
Which they duly do and then a few days later a separate email arrives saying the licence is now valid.
Did you not receive anything similar?
That surprises me, Shapfell was unlicensed from Sept 2012 until Jan this year (on tidal waters). When I applied to license her again (on phone) I was expecting questions but there were none. I was not even asked details of her mooring (she has one, paid for until Jan next year) just if she had one. This year I have a Gold license (bloody waste of money, should have got a rivers only as unforseen factors have severely curtailed my time available for cruising this year) I wonder if this had an influence on it. or possibly because she is only 25' narrowbeam and unlikely to be a liveaboard.
-
I do agree with your sentiment but your 'not fit for purpose' bit worries me to some extent.
If CRT demonstrate that they are not fit for the purpose of running the canal system then who is going to do it?
In my view they seem to be doing quite a good job of it given the challenges they face. I never had any trouble with BW to be fair since I bought my first canal and river cruising license in 1994.
I just don't think there is realistically a better option.
Hmmmm ! I think I wasn't clear enough in my meaning.
I was really pointing at the management being not fit for purpose rather than the institution ........... sorry unclear phrasing
-
The dictionary definition of reprehensible is "deserving of condemnation" with synonyms of "repugnant, inexcusable, unpardonable, unforgivable, insufferable, indefensible, unjustifiable, unacceptable"
But maybe you are suggesting differently, ie that a private individual should be "deserving of condemnation" but should be 'forgiven'
I was suggesting that a private individual breaking the law is but an individual, liable to the failings of human nature.
A public organisation should have measures in place to ensure it does not break the law.
If it doesn't it's not fit for purpose, and the blame for that lies firmly with top management
The private individual who breaks the law can expect a penalty of some sort.
but it seems that when it's an organisation no one faces a penalty.

when a private individual "breaks the law" that is reprehensible.
When a public body "breaks the law" that is totally unforgiveable.
The two are not the same

thank you for the warning Mr Bizzard, I get easily confussed at my age and a shock could be very bad for me

and occasionally in the Half Crown (they like old money down here) and and Dauntless the chandlery still only takes cash

A Wee one to start again.

On the subject of water tanks I thought you might be interested in this photo (from the Ormelite website)
This is a picture of the lower half of a Ormelite hull, the water tank can be seen forward and thwartships. It is pretty large, I don't know the capacity but full to empty accounts for about 2" of draft forward. It sits under the Vee berths in the forward cabin
