Yep spot on and good advice, as with a lot of things you get what you pay for, yes a single or cheap router will often work but a good one like Dr bobs will work better , but the key is a Good quality aerial, definitely not a cheap one, and yes some that sell for over £150 really do make a massive difference, others are a ripoff so always go for one recommended by someone who uses it and who's opinion you trust.

yep we recently had the pleasure of interacting with the southern tunnel keeper, a complete cockwomble if ever I have met one.

for fan envy I vote for one of these

search online for a boost buck converter,. you can pick them up really cheap online and is exactly what you need, just make sure it can handle at least 2.5 amps at 12v.

looks like they finally managed to crack it . http://www.mercuryracing.com/wp-content/uploads/2015/05/2557_DieselOB_SS_NC1.pdf

yep that centers your location on the map but it doesn't seem to keep your position centered as you move, I was looking for an option that would always keep your current position centered in the map as you move along the cut rather than having to keep taping the arrow to see where you are on it.

Does anyone know how to keep your location centered on the display with open canal map? i'm obviously missing something simple I hope.

Ok after a lot of trying thing out this weekend, thanks everyone for your ideas, we have found the culprit, namely the the other half was using the nesspresso coffee machine on the inverter and every time it is used it causes the problem. I guess its the extra variable load on the Alternator that causes the drop in engine revs as the heater kicks in and out and the pump is in use, however I would have thought the batteries would have smoothed the load out, but I guess not. Still thanks everyone for their Ideas and at least I now know I don't have water in my tank, the filter is not blocked and I don't have any air leaks. time for a coffee me thinks.

thanks for ideas so far, in answer to your followup questions, 1:- yes the problem happens at random times probably 3-4 times a day. 2:- it seems to happen even if the engine is not in gear and putting it into gear does not seem to make the problem better or worse. 3:-when it starts it lasts for 2-3 mins but keeps going up and down at random during the time it is playing up. I will be going back down the boat on Saturday to try out everyones ideas so any other thoughts welcome.

On our recent trip down the Oxford last week we kept experiencing intermittent problems with our Beta 38, cruising at about 1100 rpm every now and again the revs kept dropping 100-200rpm then back up again then blip up and down etc for a few seconds at a time for a couple of mins then back to normal, then ok for an hour or so and then it repeats. We checked for water etc in fuel filter, problems with something around prop, oil level in gearbox etc but for days we could not figure out the problem. before I say what we think it was does anyone have any Ideas for what caused it?

Thanks everyone for your ideas, in the end we went down and stayed in Oxford just before the Isis lock as recommended then went out onto the Thames down to the kings arms for lunch then back up past dukes cut and spent the night moored next to the meadow just north of Eynsham Lock then back down Dukes cut onto the Oxford then back up the canal through Napton and back to Dunchurch, a round trip of 9 days only interrupted by crew going down with food poisoning for 24hrs, otherwise a good trip enjoyed by all.

Thanks everyone for your ideas and comments, looks like we will be going all the way to Oxford and will be getting the day licence to do the loop on the thames. Thanks

We are thinking of spending 8-10 days going down the South Oxford from Braunston, how far do you think we should be able to get before turning back, and anywhere good to stop or avoid?

On the safety sheet for drinking water it says use 10ml Elsil per 100l of water, leave for 30 mins before using, then it remains active for 10 days.

the great thing about using hydrogen peroxide to clean out your boats drinking water system is that when it oxidises in 2-3 hours it breaks down into water and oxygen so it completely safe and does not even need flushing out, its still advisable to flush it out to get rid of the stuff it has cleaned out but not to get rid of the hydrogen peroxide. In addition to cleaning the system out it is also good to use to make fresh potable water last longer when you fill the water tank up and also to refresh water that has been in the tank for a few weeks. This is what is done on the majority of passenger airplanes to treat the water in their water tanks as you cant guarantee the quality of the water you get in some remote airports. It is also used in kidney dialysis units to remove biofilm from the water pipes in their machines, so if its safe and good enough for airplanes and hospitals its good enough for my boats water system. As with all things its important to dose it correctly so I would recommend you use a product designed for this type of thing, I use Elsil which I simply add to the tank after filling it up, it leaves no odour and is good to drink. here is a link to the manufactures information on the product http://www.skykem.co.uk/elsil-purifier you can buy it in smaller bottles for use in boats and motorhomes etc.
