vertical dimensions of wide beam

Apologies if there is any easy answer to this but I've been searching for sample plans/designs that show the vertical dimensions of a wide beam. I'm trying to understand both the external and internal dimensions, baseplate to gunnel, to highest roof point, to maximum aircraft (possibly different to highest roof point. And then similarly the internal dimensions. Bilge depth, then internal floor to gunnel height (inside) and to roof. Ideally a cross section diagram with some sample dimensions on it would be ideal.
Hope someone might be able to help. Its just a sample I'm looking for.
Many thanks
Sean

Ultrasound Tank Gauages

Hello,
I read with interest the item by Mark Langley headed "Spring Improvements" in the latest issue of W.W, in particular the item about tank gauges that use ultrasound to measure levels.
I have searched the internet and can only find mention of gauges that require the sensor to be screwed to the top of the tank.
Mark refers in his article to gauges that require no cutting into tanks and pipework and I would be grateful if you could give me any information you have as to the manufacturers of such gauges.
Many thanks,
Gary Wilson

Perkins, no thermostat?

My engine is a Perkins 100 series with a Perama Marine conversion, indirect cooling. On a sunny day going against the current on a river the engine temp gets to 70°C. On a canal going slower to about 40°C and on a cold day it barely rises off the bottom of the dial. I assumed either a thermostat stuck open, or missing. I have a downloaded copy of the manual and there appear to be two variants, one with the thermostat behind the water pump, one with it in a housing. I can't see a housing so I took the pump off and there's nowhere behind it to fit a thermostat. Am I being stupid? Or is it possible a previous owner has built a Franken-engine using parts from both types so there is no place for a thermostat?

Energy issues onboard

We have a brand new narrowboat and are newbies as continuous cruisers. After 5 hours cruising our batteries are not fully charged. Is that normal as we do not have anything on whilst we are cruising except the WIFI. When we are moored up we watch TV for a couple of hours and the batteries go down to 11.8 so we have to charge them up again. We flush the toilet a couple of times and put the lights on for short periods of time i.e. 5 to 10 mins. Our setup is 4 x SMF VETUS MATINE BATTERIES 12 V 145 AH (20H) with a VICTRON MULTIPLUS 12V 3000 VA 120AMP. The alternator for the domestic batteries is 240AMP plus solar panels to top up 20AMP. Our domestic consumables are Vetus pump out toilet, fridge 12V, freezer 12V, LED lighting, Playstation 4 240V, TV 240V 133W, Satelite dish and 4G receiver and WIFI system and a digital radio 240V.
Please could you advise us if this is normal or is our system faulty somewhere?
many thanks

Best product for protecting cabin bilge.

Hello. I've just bought a wide beam shell and would like some advice as to what's the best product to use on the cabin bilge. Is it preferable to use a bilge paint or something like black jack bituminous paint. I'm completely new to this so any help appreciated. Thanks.

Water pipe tap leak

From our water pump that sits near the bow of the boat there is a pipe that leads to the water tank then there are two pipes that run through the whole boat one above the other, both lead from the water pump. The top pipe has a tap on it and this is leaking. I don't know what this tap is for and whether it should be closed and that's the reason for the leak. Can anyone explain its use?
Thanks for the help

Ni-Fe batteries

Your recent article seemed to promote the use of Ni-Fe batteries, but when I contacted the website suggested they said that their batteries were not suitable for use on boats and they did not ship outside of the USA anyway. Is there anywhere in the UK which sell them, and if so, are they suitable for boats?
Regards,

Long Term Hire

My wife and I are fairly experienced boaters who currently own a share in a boat. Being now both retired we would like to have one long term cruise to explore at our own pace - between 3 and 6 months probably, but we don't really want the hassle of owning a boat we might want to sell after a year or two. I have found several websites such as Escape the Rat Race and Laughing Dog Boats which offer long term rental, but having survived the Ownerships collapse and being aware of the current rather dodgy market for liveaboard rentals, we are anxious to make sure any arrangement is reliable. We don't remember any coverage of this in WW and wondered whether you or your readers could provide any advice?

Connecting battery negative to hull

A few months back I had someone look over the boat and I was told the battery 0V must be connected to the hull bonding point to pass the BSS. Is this correct?

Stainless steel water tanks.

This is not a question but our experience. We found water in our cabin bilge and went through the process of checking pipework for leaks (none), checking condensation collection, (none) and nearly gave up thinking the hull must be leaking. At only 7 years old and having had an out of the water full survey before purchase we took it that a stainless steel water tank would not be the problem. We finally disassembled furniture, bed and front bulkhead to gain access and found that indeed the corner weld were leaking and also causing rust to appear in the domestic water supply, which we had put down to sand etc in the canal side water feeds. It transpired that the tank had been welded with MIG welding and stainless requires TIG welding. It cost us nearly £700 for a new tank and much hard work to fit and re-build the boat and much lost cruising time. This would not have formed part of the pre purchase survey. The moral is, check your bilges regularly and the colour of your water from the taps etc. Our new tank now includes an access hatch to allow us to inspect the condition with the tank drained down. Hope this is of interest.

Solar panel wiring

Our boat has the output from the charge controller feeding direct to the Domestic Busbars which are fed via an isolator and fuse from the batteries. Should the Solar panel wiring go direct to the batteries with a fuse for protection. We don't usually isolate the domestic isolator.

Boat Width

Hello.
Does the width of a boat matter when you exceed 6ft 10". More specifically is a say 9ft boat able to access more canals than a 10-13 ft boat.

Stove or aga

Hi after living on a Narrowboat for 5 years we've decided we have outgrown our boat and looking to buy a widebeam( not everyone's taste) but living on a boat with a 8 yr old boy we've outgrown a Narrowboat and don't do much cruising so widebeam is far more practical for the next few years. Would you go for a stove or a solid fuel cooker? Tia for your opinions
