easier with a bow thruster incoming.............

Sorry for the delay in responding Colin I have been away for a few days. My hatches are edged in box section so I just drilled iin from the sides to hold the wood. I see no reason why you cannot drill through the steel face of the doors/hatches and use coutersunk screws so you can fill and paint to leave no trace! I have seen this done on a number of other boats! Gary

I wouldnt use airtec foor a door as you will end up with a very thick door in order to get the correct airgap either side of the airtec. I used just old capet/underlay between the wood and the steel. i sealed the edges of the woood and this seems to work ok with no condensation problemshope this helpsGary Thats exactly what airtec is like! Hard to believe its insulating qualities are equivilant to 50 mil or so of polystyrene, but it is. There is a test of the stuff somewhere on the web which I think was mentioned somewhere elese on this forumGary Is this link correct? all I get is a fiberglass products company?Gary This looks a lot like thinsulate and maybe cheaper?Gary

It might work but ideally you need to leave an air gap either side of the airtec. Gary

and the force applied to its end is dependant on the fuel air mix entering the cyclinder which is dependant upon the gov setting which in turn is dependant upon the load. Hence power (the rate of doing work = force x distance x time) is proportional to both torque (which is dependant upon how much fuel/air mix is going into an engine at a given RPM) and RPM Gary

Yes exactly, conservation of energy really, every action has an equal and opposite re-action and all that. If you ran an engine uncoupled as 1200 RPM it can only be producing enough power to overcome its own inefficiencies. If you coupled it up to a load the gov would try to increase power at that RPM to match the load. Torque and horsepower are not just dependant upon the RPM, the amount of fuel/air entering each cyclinder also is a great factor! energy in = energy out - inefficiencies Gary

I have used this on the roof sections of my barge. I trapped it inbetween the box section roof beams and the battens to give an airgap above and below as per the instructions. Seems to work rally well but needs sealing completely as per a vapour barrier to prevent warm air coming into contact with the steelwork. So far I have had no problems with condensation - During a particularly cold period one time I removed some of my cladding, peeled back the airtec to find that the steelwork behind was dry as a bone. The main advantage of this stuff i would say is its cost and the fact that you can get to the steelwork if you want it is also very easy to install overhead. Main disadvantage is the need to seal it completely but for the roof this did not prove to be too difficult. Gary

Looks like it could be perhaps a bargain for those willing to put in the work http://search.ebay.co.uk/search/search.dll...russell+newbury

Can a borg warner gearbox be 'freewheeled' i.e. can the output shaft be turned for any length of time (with the engine off)without damaging the box? Gary

so what size calorifier would you need for a modest size domestic bath? would 75 liters be enough? I have had a quick measure and our bath seems to hold about 115litres when filled to a reasonable depth (1.05 x 0.46 x approx 0.24 metres)

I recently broke down on the tidal trent in my barge and as a result of this experience am considering fitting a 'wing' engine to my boat. The boat in question is a flat bottom 55' x 10' barge whcih has a perkins 6354 as its main propulsion unit. I was cosidering something along the lines of a 20HP diesel driving its own prop. I have seen such an arrangement on see going boats but never on a barge. Has anyone any experience with this? What about the helpful chaps at ledgard bridge? regards Gary

I was lucky enough to be given a light very similar to this the other day. Made by lucas, with a beam adjustment thingy on the back. Gary

I am with you Carlt...it would appear that certain other parties have lost the plot!

To do this just connect the pump dicharge to the pump return i.e. T off your discharge pipe, take a loop back round and T into the inlet pipe. I think this is what was meant. Gary

I would be interested in this PWM circuit if I could have a copy please Pete regards Gary

fitted 100HP to my 55 x 10, glad I did. Boat can make good headway on the tidal trent against the run of the tide. Gary

Interesting article in towpath talk regarding mooring auctions amoungst other things!

The normal route is that a scientist puts forward a 'theory' this theory is then open to assessment by their scientific peers who either prove or disprove or otherwise the theory. It may be that the theory develops as a result of further research. thorugh this process that facts are approached.

Dont get John started about liveaboards By the way how much time can you actually spend aboard a boat before you are calssed as residential. In a previous post I mentioned a collegue of mine who lives in a hotel six nights of the week - is his residence the hotel as he sleeps their most of the time? Seems to be a grey area - no formal definition of residential!?

Groan.....look up corrosion in a decent textbook or on the web and you'll find that it is primarily an electro-chemical process! yes indeed rewriting the laws of chemistry/physics. A for the 'piiting only became a problem with the fitting of anodes' - corrolation between one event and another does not neccessarily mean the two are interelated.

We travelled from the thames to west stockwith this summer via the grand union, nene, wash, witham, fossdyke and the trent. Seems that all the miserable boaters were on the grand union and all were in very shiny narrwoboats which probably dont move very far. The river sections of the journey were by far the most enjoyable.

I think you will find that some of the moorings earmarked for closure have been there for years, not recent additions to fill demand. Food for thought but from what I hear (from experienced people) the waterways in france are much better maintained, you get treated a lot better as a boater, and everything (bar fuel) is a lot cheaper! Why do we have to mess things up so much in this Country? Why cannot BW just leave the linear moorings be and just aim not to introduce more? NB it will be interseting to see whether this years weather has put off a lot of wanabee boaters. I know in my area things have been very quiet. Perhaps BW shuld take note and start looking after its 'failthful customer base' (what a landlord might call his regulars). These may just be the people that keep the system going should the recent weather prove not to be a freak incident.

Couldnt agree more! Brings to mind people who are new to canals and like what they see so buy a boat and then start compalining about lines of linearly moored boats?! Perhaps BW have in their 'wisdom' been listening to such people hence the attack on online moorings. Moorings that have been there for years unlike some of the newbie and status boaters.
