High Charging Voltage Problem

Our boat is fitted with an Iskra 100a. alternator and an Adverc management system. Since fitting, five years ago, the alternator has charged as it should - cycling between about 14.1v & 14.5v through the Adverc system, measured across the starter battery terminals on the boat's built-in digital voltmeter.
Late last summer, the charging voltage abruptly changed to 14.7 - 14.8v - the boat's meter agrees with my hand held multimeter and with two others, one used professionally, so no question of faulty meter.
Disconnecting the Adverc made no difference - in any case, the Adverc will control up, but not down.
The alternator went away for a replacement regulator, but this too has made no difference.
The boat is also fitted with a Sterling 3-stage charger : the first stage 'boost' charge should be 14.4v, but is now 14.8v.
The batteries (1 x 96ah + 2 x 110ah) are only 3 years old, and hold charge very well, but are tending to need topping up regularly.
Do I have a problem ? - and if so where is the likely culprit, and how do I confirm ? I do not want to spend nearly £300 on new batteries on a hunch that they may be the cause.

Too many windows

Ive just bought a hull that the previous owner had started to fit out before making the windown watertight. Most of his hard work has been undone by water damage. Now this boat has 'lots' of windows and marine windows are expensive. Has anyone ever decided to blank off any windows on a narrowboat and if they did, what did they do? thank you

John Southcombe

Hi I have a cooling problem I have renovated a 37 foot narrowboat with a 1.5 BMC diesel the temperature does strange things it takes a very long time to warm up goes to 80 drops to 40 and sometimes does not cool but overheats. so there's the symptoms.
The engine cooling circuit seems strange it has a bowman manifold that has been disconnected from the water supply. it has twin keel tanks the R/H tank is the inlet for the existing bmc water pumpthe left hand tank has a Jabsco pump attached I first thought this was pulling water out of the engine from the thermostat but it is no its pumping water into the thermostat the back of the cylinder head had an outlet on that is feeding a header tank this tank splits and returns the water back to the keel tanks.
firstly is the BMC water pump man enough to circulate both skin tanks they each hold 40 litres.
would it be better to put the jabsco inline the the engine pump the help delivery.
Thirdly has anyone got a layout they can share with me. Overheated twice now damaged an impeller and think I may have cooked the head need to sort this out I believe it has had some tinkering with by the previous owner. The boat was stood idle for a couple of years and is now back to her former glory apart from the engine problem.

french varnish

I am trying to find the name of a particular varnish, made in France, that I saw demonstrated at Crick Boat Show. The finish was absolutely wonderfull and in addition to this, the varnish sank into the wood, not just sitting on the suface like modern products.

Drive problem

I have an Isuzu 35 engine coupled to a PRM120D gearbox via a centraflex shaft coupling. When selecting forward drive the contact seems quite heavy and is not smooth like on other boats I have owned. This was picked up during a recent survey and as a result a new drive plate was fitted with little or no effect. My boat is 6 years old. Any ideas please.

how can I identify my narrowboat No 46786

I purchased my 40ft narrowboat "Lockwood" No. 46786 7yrs ago for major renovation. ( I understand it had been out of the water several yrs then. I contacted BW and asked if they could give me any information on the boat but said they had no record of this number. No makers plate or numbers are present as far as I can tell. The hull is made from 1/4" plate and the upper cabin is timber beams & boarded, It has a josher style bow & swept up cabin at the traditional stern end.Any help would be greatly appreciated as I am aiming to have it in the water next year.
