When I read a post on the forum which I think may be of use to me in the future I would like to save it. Is there any way to archive individual posts (or even threads) within the forum site for easy recall at a later date without having to resort to the search facility, where I often cant find what I am looking for?? tosher.

Thanks for all your responses, I bought the Universal DC Power Supply from Maplins as suggested and it does the job nicely. Cheers -- tosher.

If it is any help to you I use Elecsol batteries and the SG on these is lower than other types of batteries. From memory the SG when fully charged is about 1.25. tosher

Is there a simple way to power a 6volt appliance from the boats 12volt DC sockets? I have a digital TV aerial which has an internal booster. This booster is supplied with 6volt DC from a power inserter plugged into the aerial coax cable at the back of the freeview box. This power inserter is supplied from a 240volt AC plug with built in transformer/rectifier but unfortunately the nearedt 240 volt socket is some way from the TV which means trailing cables. Right next to the TV is a spare 12 volt DC socket so my question is ---- how can I supply the 6 volt DC power inserter from the adjacent 12 volt DC socket ?? The details on the power inserter say 6 volt DC 100ma but the actual measured voltage when plugged into 240 AC is 8 volt DC.

You must have a 3:1 pulley ratio to get that output as the normal 2:1 would only achieve about 120 amps max.
Chris
Just an update, you are quite correct chris, the pulley on the engine is just over 9 inches dia. and the pulley on the alternators is just under 3 inches dia. tosher.

I accept the arguments, but it is not just old ones. If I were to evacuate the building and dial 999 every time my smoke alarm triggers I would have an injunction on me quicker than you could say "False alarm".
Come on "snibble" keep yourself safe. look at www.diconsafety.co.uk I've had two of these installed for almost a year now without a single false alarm. They were given free of charge by the Cheshire Fire Brigade when they did a free inspection of the boats in our area. The only time it goes off is when swmbo's cooking gets out of control and fills the kitchen with smoke!

hi my pump out is on roof works well
Hi "Bob the welder" Shortly after my original post I bought the boat with the punp out roof connections and it has worked fine with no problems for almost a year now. Not yet got round to a self pump out system though. Thanks anyway for your post. tosher.

Had this once on a sea going yacht, Perkins engine/Hurth gearbox. Afraid nothing but a recon gearbox cured the problem. Incidentaly it was caused by who ever fitted the gearbox fitted the linkages the wrong way round, so when the gear lever was pushed forward the boat went backwards. and pulling the lever backwards the boat went forwards. The cleaver dock yard maties overcame this problem by simply changing the pitch of the max prop from right handed to left handed which cured the direction problem but of course meant the gearbox spent most of it's life working in reverse gear. It worked like this for 15 years before the gearbox finally died. The cause was diagnosed by a very knowledgable Perkins engineer who fitted the replacement gearbox and out of interest I asked him what the reverse gear time rating was on a Hurth mechanical gearbox and he replied ---- 30 MINUTES !!!! tosher.

I use 120cm 12v x 0.25amp computer cooling fans, one in the galley mushroom vent and one in the bathroom mushroom vent. They cost less than a fiver and last for 30k hours. The one in the galley is on a simple on/off switch and the one in the bathroom is on a timer switch (stops after 10 minutes). They work very well, draw little current and cheap as chips. tosher

My boat is on a John White shell. No problems or faults at all. Well built, nice to look at, handles well, sound as a pound and dry as a bone after 1 year afloat. tosher

You've got me there, not sure what the pulley ratio is but out of interest I will check when next on board. tosher

I have a Sterling 210 amp Alternator-to-Battery charger with both alternators (110amp & 70amp on Isuzu 42hp engine) connected together. This has worked fine for a year now with no problems at all. I also have a remote control panel which shows alternator output and on occasions when my batteries were a bit low I have seen this reading 150amps which is a good indication that both alternators are working ok. tosher

I understood that lighting circuits do not go through the RCD on domestic systems, only socket outlets use the RCD. That is certainly the case at home but my house was wired 10 years ago, things may have changed now.

Just found out that Baddiley locks are closed till 7th March. That has completely mucked up our plans as we were heading for the Montgomery. Does anyone know why the plans were changed?
With Yard Lock at Stone closed and the Audlem flight closed our cruising is limited.
Fed up Sue
Repair of paddle chambers required to secure navigation through 2008. At least that's what it says on Waterscape web site. Oh and BW "appologise for any inconvenience cuased" Totally cocked up my plans as well. tosher

That should be number 1 on any list - especially if you have an engine like ours - we had to use the big 'ammer only yesterday to re-tighten the thrust bearing collar on the gearbox . . .
I believe "impact adjustment" to be the technical term for this type of activity???

If a boat is catching you up, or following closely, I really don't see what is wrong by slowing down and pulling into the side.
I agree entirely, If I am having a "slow" day and another boat catches me up I automatically assume they would like to pass me and pull over accordingly but unfortunately not all boaters see it that way. On several occassions last summer I came up behind boats going very slowly (no problem at all with that) and I approached them reasonably closely and assumed they would take this to mean that I would like to overtake them but not one of them would let me by. I had to follow them for quite some distance going so slowly I could only engage gear for half the time, the other half with no steerage way. I meant to post at the time to ask if there was any recognised way of letting boats in front you know that you would like to overtake them but reading the preceeding posts it would appear not.

A Challange for all dog breeders -- to design and make a dog that only needs emptying once a week and preferably one that eats plastic bags so the sh@t comes out already wrapped !!!! Just a thought.

Dont go for that make of battery, there are many better brands that that one. I know of a few people that have had problems and been told to go away when they tried to claim under warranty.
They are no more resiliant to bad charging regiemes than any other battery and will die just a quickly if mistreated.
Julian
On the contrary I have had 3 x 270ah Elecsol batteries on my boat for over a year now and they've never given a minutes bother although I do have an external regulator (Sterling) as "chris w" suggests. They hold their charge very well when the boat is left unattended with no charging at all. The warranty is for 5 years but never having had to make a claim I cannot comment on it. tosher

Went passed Wrenbury last weekend and everything at the Alvechurch base seemed to be in "winter" operating mode with most boats apparently laid up. The actual basin was full of boats but also there was about 20 or 30 boats tied up to the canal bank on either side of the basin, some on the towpath side and some on the off side. When I licence my boat I have to have a marina berth or have a continous cruising licence and move on frequently. Are hire boat company's excempt from this rule or are they just flouting it. ?????

Does anyone else find the site slow to load? I've gota good broadband connection, and most sites, e.g. BBC home page, load instantly. However CWF seems to take ages with the browser (Firefox) saying "waiting for www.canalworld.net".
Logged on with Firefox 15 minutes ago -- no problems. tosher

A spurious argument all this.. Power stations burn fuel too, you need to add all the losses together to get a sensible figure for electricity.
After spending 30 years burning coal in power stations I agree entirely with what John says above. The most modern of our large coal fired power stations operate at a maximum efficiency of around 38%. So for every 100 tons of coal burned only 38 tons (equivalent) of electricity is produced, most of the remaining 62 tons being lost in the hot gasses (pollution) going up the chimney and in the steam going up the cooling towers. A typical 2000 mw power station burns around 20,000 tons of coal PER DAY and of that around 12500 tons of coal PER DAY is lost to the atmosphere as waste heat. The notion that electricity is a clean and efficient fuel is very much a misnomer. (I burn free wood on my stove, seen enough coal to last a lifetime).

We have recently purchased our boat which has a very efficient squirrel stove in the saloon. I am about to fit a new single skin chimney( though definitely not this weekend looking at the forecast!!) and wish to find the best sealant/adhesive to attach it to the mounting flange on the roof. There is also a problem with the seal through the roof and some nasty black drips running down the pipe indoors. I have cleared all the old sealant which looks and feel like black putty. Any advice ploease.
I don't use any sealant at all simply because I always remove the chimney when cruising to avoid losing it on low bridges and the odd excursion into the bank side trees and bushes. The chimney is double skinned and is a reasonably tight interference fit on the base flange. Occasionally I just need to wipe off the small amount of gunge that appears on the roof after several day's in use (burning wood). Never had any problems. tosher.

My opinion is if there's any doubt about it's suitability then don't use it. What you are suggesting is a false economy and I see no need to risk damaging your batteries since you can buy a 4 litre container of distilled water from a big Tescos for a couple of quid.
Thanks "blackrose" I think you have a point there. tosher
Cratch Board
in Boat Building & Maintenance
Posted
I have the same dilema as you Ray in deciding on the design of a cratch and wondered if you have progressed and what the outcome is. If it's not too late, an idea I have is to use an open "A" frame at the front with no central upright and to use a removable canvas front panel with plastic window that could easily be unzipped and rolled up giving free access to the foredeck. Has anyone else experience of this type as I have never seen one in use??? tosher.
