I am going to fit a calorifier to my boat and would like to know the best take off and return points on the engine cooling system for the heating coil. The engine uses a closed cct keel cooling system - any thoughts gratefully appreciated

n/b lenghts

My Wife & I are planning a new build n/b, for post retiral long term cruising, south of the border.
Initially based/ built on Lancaster or Leeds & Liverpool
We would like to have a minimum length of 60' but 65' would be better.
We hope the build will be high tech diesel / electric hybrid drive, hence the length requirement.
We currently own a 53' semi-trad ( so we are not newcomers ) moored here on Scotland's Union Canal.
The question is...WHERE WILL WE NOT be able to cruise @ these lengths ?
I suspect 65' leaving the Lancaster will be on the back of a truck !!!!!!!
All info & assistance appreciated
Gordon & Jennie

How do I solve discolouration and odour in domestic water supply?

Our boat is only just 12 months old. It has had a problem with orange/brown deposits in the water for some time. The builder told us "it was not uncommon with waterside supplies" but it is now much worse. When the water is run - at any point on the boat - after not being used for a few days, it runs mid to dark brown and has a very unpleasant odour. This clears after a couple of minutes. We have drunk the water (filtered) with no ill effects. It was suggested it might be a degrading diaphragm in the accumulator. The whole unit was replaced, but the problem continues. Any suggestions or solutions?

PDF Files Missing?

As a subscriber I regularly come to your site for the latest news and info. But, and there always has to be a but doesn't there? Why are there no PDF files available for downloading after April 2005... has there been a breach in your database? Apart from this one small question I am more than happy with the magazine & web site.
Best wishes, Kevin

Narrowboat condensation during winter?

Can anyone suggest a solution to the condensation and high humidity problem in a narrowboat during the winter months. The humidity is constantly very high and the woodwork expands. I have used calcium chloride crystals in the special containers, but they make little impact. I don't want to run an electric dehumidifier over winter if I can avoid this. Has anyone any experience of the solar panel ventilation system by Solarventi?

Bleeding Diesel Fuel Filters

I have a 50' Mike Hayward narrowboat with a BMC 1.8 diesel engine. There appears to be a pre filter before the fuel pump follwed by another fuel filter afterwards. I cannot get the pre filter to bleed even though I have removed both of the bleed screws. Any thoughts please? - Many thanks

Lights dim when fridge cuts out

Strange but true, when our 12 volt Shoreline fridge swithes off the wall lights noticeably dim and when the fridge cuts in the lights brighten.
It has been suggested that it could be an negative return fault but as the two circuits don't join until they get to either the positive or negative bus bars I can't understand what I should be looking for.
Any suggestions welcome.
