talking anodes

Talking anodes for most people would consist of a series of questions. Every boat owner knows that anodes are needed, but what are they, exactly, what do they do, and why do we need them? What follows is an attempt to answer all of these questions.

magnesium anodes for welding onto boat hull. tecnoseal.what is an anode?

An anode is basically a plaque of sacrificial metal which is welded or bolted on to the underwater hull of a boat. Sacrificial because the anode corrodes through electrolysis more readily than the steel hull, thereby protecting your boat’s hull for longer. With steel hulls, they should be welded on, for other hulls they can be bolted on.

how does it work?

There will be a series of different metals which make up the exterior of your boat – the hull, propellor, propellor shaft are made from various metals and alloys. When different or dissimilar metals are in direct contact, and immersed in water, the water acts as an electrolyte and an electron current is sent from one metal to another. This causes elctrolysis: one of the metals loses material in the form of ions (this metal is known as the anode) and another metal gains material (known as the cathode), and which metal loses the material depends upon how noble or corrosive-resistant it is. The noblest or most corrosive-resistant metal would be gold, while the least corrosive-resistant or the least noble is magnesium. Basically the strongest metals are protected and the weakest loses ions therefore breaks up (corrodes). The less resistant material becomes anodic and the more resistant material becomes cathodic.

anodes in place on narrowboatdo I need anodes?

Of all the metals that exist in your boat, the weakest, least noble and therefore least corrosive-resistant one is your steel hull. So it should be apparent from the above that if you did not have anodes fitted, and replaced regularly, the steel hull of your boat would become anodic and therefore corrode at a much greater rate. For a canal boat (narrowboat) it is very advisable to get anodes which can be welded on to the hull, as drilling holes in steel below the waterline isn’t the best option. The anode then becomes anodic, and the steel hull cathodic – which means it won’t rust so quickly.

what sort of anode do I need for a canal boat?

Anodes are manufactured in zinc, aluminium or magnesium. For narrow boat owners, wide beams and other steel hulled canal boats, magnesium is the preferred material. Zinc is used for sea going boats, and aluminium for brackish water. (Brackish water is water having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater with fresh water together, as in estuaries and tidal rivers). Of these, aluminium is lighter (therefore cheaper to install) and less costly than zinc.

sacrificial anodes in situ on narrowboatchoosing your anodes

Make sure your anodes are fitted correctly and purchased from a reputable supplier. You will need professional advice about size of anodes, placement and quantity. It is not a good idea to overload the hull with anodes as this can have a detrimental effect on paintwork.

Remember, the anodes are added to your boat to sacrifice themselves, in order to protect other metals. If the anodes are not corroding further investigation would be required as the anodes once fitted and stable should start to show some sign of corrosion soon after.

In summary, make sure you buy anodes from a reputable dealer. Get the right sort for your boat. Get professional advice on size and placement. And get somebody to weld them on to your boat. When blacking or painting your boat, make sure you go round the anode, as painting over it would prevent it from doing its job.

Keep an eye on your anodes, and your hull will look after itself.

musings from the boat painter’s workshop

musings from a boat painter's workshop

thoughts of laser cleaning as an alternative to sanding...

It can be a quiet life, the painting of boats. After the hard work of boat surface preparation is done there is time for quiet contemplation and communing with one’s paint brush. Rather like Mr Miyagi’s instruction of “wax on, wax off”, we spend many hours moving a paint brush from the bottom to the top of a 1 metre cabin side. Paint up, paint across, paint down; all very rhythmic and calming. Some workshops play loud music to fill the hours but, after the din of grinders and sanders, peace and quiet is what we prefer.

boat painters workshopSo, what goes through our minds as we literally watch paint dry?

Of late, I have been thinking about laser cleaning. I’d seen a couple of YouTube videos and thought – Wow! That can’t be real surely and, if it is, why aren’t we cleaning boats with lasers?

A good paint job is all about the preparation; if narrowboats could be properly prepared, cleaned and de-rusted with minimal mess, minimal effort but maximal cleaning and rust removal narrowboat painting could be revolutionised.

The current options of grinding or shot-blasting are very messy, very labour intensive and are only as good as the effort that is put in.

Laser cleaning vaporises the paint and rust – cutting down the mess, the laser “gun” is not heavy – cutting down the effort and the finish is clean enough for the nuclear industry.

Want to know more?

I took the time (so that you don’t have to) to make further enquiries, attending a symposium on the applications of laser cleaning.

Laser cleaning equipment is used in many industries. Artworks from the Old Masters benefit from laser cleaning. The depth of the laser penetration can be very finely tuned so centuries of dirt can be removed without any damage to the painting. At the rougher end of the spectrum, laser cleaning was adopted for the cleaning of concrete walls on Dublin’s Harbourside as more standard, but more aggressive, methods of cleaning such as shot-blasting was not permitted.

Laser cleaning has been used in high tech industries for around 30 years. As a boat painter, the most relatable for me was the use of lasers for the pre-cleaning of metal prior to welding. This is done for the welding of car components and nuclear waste containers (where the strength of the welds is super important!). Typically, lasers are used in conjunction with robotic systems. The “laser robot” will clean the metal plate seconds before the “welding robot” does the weld. Cleaning the contaminants seconds before the weld increases weld penetration making the bond stronger.

But, I hear you cry, weld joins only cover a very small area; it would take forever to clean a boat with a laser beam of 0.02 mm width. Fortunately, beam width and laser power have been increasing with developments within the laser industry. Laser heads now exist that are a suitable proportions to work with narrowboat sized objects.

I have seen the technology with my own eyes on my own dirty, rusty, painted piece of steel, you will have to trust this YouTube clip

Can your boat be cleaned by lasers?

Yes! But, as a small business owner, I have to say it will be no time soon. For laser equipment of a suitable size to clean a narrowboat it would cost around £500,000. That’s a lot of boats to be cleaned before it pays for itself.

But who knows what the future holds. Today, we each carry more computing power in our hands than could have been bought with £500,000 forty years ago. Laser technology is constantly developing and being adopted by different industries. Maybe in time it will be affordable enough for every boat yard to have their own laser cleaning equipment.

gailey wharf training centre

birmingham and midlands marine services – water safety training centre

'BMM' is a small business; just myself (with the help of 'Morgan' the dog, my Lurcher), my Wife Francoise assists with the website, Frans, Aubrey, Bob, Carl and Adrian are all part-time, freelance instructors with Bob acting as equipment manager and helping me run the jobs and training we offer.

BMM TRAINING As a canal based business we are quite unusual; based at 'Gailey Wharf' on the Staffs & Worcester Canal we are predominantly 'commercial' trainers for personnel working within three metres from the water's edge and of course, on boats as part of their job. We also train members of the public who have been told by their insurers to get a qualification in boat handling prior to being able to obtain cover for private canal and river boats.

gailey wharf training centreThe 'Leisure' industry on the canals and rivers in the UK is a hugely well catered for sector: the commercial side of things was an untapped market. 'BMM' are filling this gap with a range of services that was otherwise untouched.

A few points that most Folks are unaware of:

  • Anyone steering a boat whether as paid employment or a volunteer requires a licence to do so. A Maritime & CoastGuard Agency 'BoatMaster's Licence (Passenger operations / towing and pushing / workboat endorsement) is the main licence, the RYA Inland Waterways Helmsman Certificate / NCBA Certificate in Community Boat Management / IWA Certificate of Boat Management or the RYA Powerboat Level 2 licence / qualification are the MCA 'recognised alternatives' to the BML.
  • gailey wharf training centreAn employer / organisation / trust putting personnel near the water's edge; 'should the risk of accidental immersion have been shown in the risk assessment' are obliged to provide water safety awareness and APPE (Aquatic Personal Protective Equipment) training to their personnel. Particularly relevant should those personnel 'be managing groups'.
  • gailey wharf training centreAnyone working within the wider civil engineering / construction / maintenance / utilities / rail / environmental sectors within three metres of the edge (same point of reference 'R.A' as above) is obliged to have received water safety awareness and APPE training under the 'Construction (Design and Management) Regulations 2015.
  • An employer / organisation / trust issuing 'APPE' to personnel (paid or volunteer) such as drysuit, waders, lifejacket, buoyancy aid, helmet, throwbag should ensure that the recipient has been properly trained in the equipment. Not having an accredited qualification or sufficient in-house training by an appropriately qualified instructor would be seen by a Judge in the case of a fatality at work as negligent, resulting in a 'corporate manslaughter' charge.

Gailey Wharf Training CentreHaving worked as an MCA BoatMaster commercially  since the 1990's and many years as a safety & rescue boat operator and rescue technician the evidence was seen on regular basis to show that professional commercial training was needed for the canal and river environment. That was why we started 'Gailey Wharf Training Centre'; to try and make a difference.

Clients arriving for training with their own lifejackets, issued to them by 'work' far too regularly have not been shown how to wear them correctly, what to check, and we find many lifejackets wouldn't activate in the case of an immersion because they are not set up correctly. A bit worrying really! Folks issuing lifejackets without a grounded knowledge of how they operate isn't acceptable!

Gailey Wharf Training CentreInitially we began running 'commercially orientated' skipper training aboard a commercial vessel. Many folks that have undertaken a boat handling licence did so on a 'holiday hire' type vessel or a standard narrowboat. This is ideal for 'leisure' boating but does not train the candidate in commercial handling, for example all the manoeuvres and control needs to be from the stern rather than crewed from the bows - no access through on commercial vessels when loaded.

We than became RYA trainers; Inland Waterways Helmsman Certificate courses, then MCA BoatMaster training including water safety & personal survival, boat fire safety and small craft first aid.

Gailey Wharf Training CentreWe then branched out to water safety awareness then rescue training via the Royal Life Saving Society: for employers we provide the 'National Water Safety Management Programme' and Outreach Rescue 'Water Rescue Awareness' and Water Rescue First Responder' training. For those personnel without a statutory duty to respond we also run a short course; the 'Water Rescue Equipment Training' course developed again by the RLSS.

Gailey Wharf Training CentreNext we commenced training Powerboat operators intending upon a career in the marine rescue sector - RYA Powerboat Level 2 and Outreach Rescue 'Powered Boat for Rescue Response' - ensuring that safety boat teams working on contracts on the inland waterways have a comprehensive background in ensuring their clients safety. This is something that needs to be acted upon as the accepted industry standard is a very basic qualification and leaves room for accidents, injuries and fatalities.

Further to our training role we provide workboat, safety boat and marine rescue services: with rescue boats 'in-water' swimmers and 'bank-rescue' teams. We provide workboats and procurement services to organisations working waterside, sourcing boats, pontoons, scaffolding, divers, APPE and rescue equipment.

Gailey Wharf Training CentreFinally, we move commercial vessels by water to and from 'site' on behalf of commercial contractors and commercial boat hire companies - nice to get some peace and quiet on the way to 'B' from 'A'!

bow thrusters you can trust

wondering what is the best bow thruster for your boat?

THE VETUS BOW PRO THRUSTER SERIES - the best of all worlds!

This (r)evolution from VETUS is a combination of our renowned electric bow thruster series and the latest induction motor technology. We are pleased to present the all-new BOW PRO thrusters, the best of both worlds!


Vetus pro bow thrusterPrecision control at your fingertips, you command as little or as much power as needed!

• Fully proportional control from zero to full power

• Endurance Rated Run-time - In excess of 5 minutes at full power

• Maintenance-free brushless motor

• Sealed ingress protection construction - motor sealed for improved corrosion resistance in damp environments

• Built-in over-temp and low battery voltage protection

• Suitable for highly demanding applications (e.g. for use in rental & charter vessels)

Revolutionary concept matched with proven technology

Our BOW PRO thrusters use proven induction motors without carbon brushes. As a result, the bow thruster motor is maintenance-free and has Endurance Rated* run-time!

Why is this important? A conventional DC motor creates a lot of heat and the running time is limited by the amount of heat it can dissipate. Typically this could be just 3 minutes in an hour before the thermal cut-out trips. The carbon brushes in a DC motor also wear. The higher the current and heat, the faster this happens and can cause a lot of black carbon dust in the boat. The BOW PRO has none of these issues.

The induction motor is controlled by the VETUS MCV motor controller which can handle both 12 V or 24 V on board systems, making the new BOW PRO thruster suitable for almost all boats. The built-in over-temp and low battery voltage protection, combined with the brushless induction motor make the BOW PRO thruster series highly resistant to abuse and ideal for beginners or experienced users alike!

The BOW PRO thruster is controlled by a proprietary CANBUS protocol (digital control) network. There are two fully-proportional panels available for the BOW PRO thruster series; one standard panel (BPPPA) and one panel with lock-and-hold capability for easy docking (BPPJA).

BOW PRO thrusters utilize the same propellers and gearboxes proven in VETUS thrusters for over 30 years. Upgrading a boat with an existing thruster to a BOW PRO thruster is easily achieved as the BOW PRO thruster was made to share tunnel sizes with current VETUS thrusters as well as many other brands.

*BOW PRO thrusters will run for 5 minutes at full power, providing the battery bank allows this. After this time they will automatically reduce the power output, but will continue to run until the battery is depleted. If less than full power is used from the outset, then the run time is greatly extended!

All this technology is available for not significantly more than a conventional DC thruster and the installation costs are roughly the same. If you are considering installing or changing your bow thruster then ask whether you will get the following benefits:

  • Full proportional control from zero to full speed.
  • Option for “lock and hold” control panel. Set the thruster at whatever speed you choose and lock it running while you moor the boat.
  • Brushless sealed motor with no maintenance, no wearing parts and no carbon dust.
  • Long run times. Five minutes or more at full power and considerably longer at lower speeds.
  • No thermal cut out. The motor will continue running as long as the battery bank allows.

Boating Leisure Services were one of the first builders in the UK to install a BOW PRO thruster. They fitted model BOWA0651 into their new narrow boat displayed at Crick Boat Show in May 2018.

installation of Vetus bow thrusterBoth the owner and his employees were very impressed with the system.

After a trial of the boat in the windy Heyford Fields Marina, business owner Gary Manning said “The installation is as easy as any other thruster. It is the best system I have ever used and well worth the money.” When Gary was asked whether he would install a Vetus Bow Pro again, he said “Definitely! It is an amazing bit of kit and it re-invents how thrusters can be used with a whole new concept. I’m very impressed!”

The installation looked neat and tidy with ventilation either side of the locker. The noise from the thruster is lower and less harsh than a standard DC thruster giving a smooth operating noise.

The system is powered by 2 x 105Ah batteries. Controller used is the BPPJA proportional “lock and hold” joystick.

clear blue loo, brought to you

by Wessex Chemical Factors

The family run business based just outside Bournemouth started out supplying the engineering industry with lubricants and cleaners, but over the years have developed solutions for a myriad of different industries, becoming specialists in marine, motor-home and leisure applications.

The secret to their success is their willingness to work with their customers to find the right solution for every job, concentrating on lower costs and environmental safety at every step in the process.

No other product illustrates this versatility more than their groundbreaking environmentally friendly toilet fluid Blue Bio. Launched at a time when 99% of the leisure industry used formaldehyde or glutaraldehyde based products that simply preserve waste until it can be off loaded at a suitable processing station to be treated as hazardous waste, Blue Bio was a game changer.

A new generation, multi-purpose toilet fluid that could be used in cassette, waste and flush tanks in motorhomes, boats and narrowboats, but also suitable for septic tanks, boat holding tanks and grey tanks, Blue Bio quickly became an essential part of many boat and caravan owners ‘must have’ products and the reason for this was simple. Blue Bio was different.

Working alongside mother nature, Blue Bio utilises natural live bacteria to break down waste meaning that at no point in the process is your waste ever classed as hazardous or chemical waste, greatly reducing our customers impact on the environment and reducing disposal charges as their waste could simply be flushed down a toilet.

Blue Bio quickly became one of the company’s fasting selling products, with Linda French of Ownasharecruising becoming one of our best customers, using the product across her fleet of narrowboats.

Last year however Linda contacted us with some feedback that would change everything. Something that’s unique to narrowboats is that many of them have stunning wooden interiors that even with the washable dye mbv could easily become stained or tarnished by the colour of Blue Bio if a spillage occurred, so whilst Linda’s feedback was overwhelmingly positive she did ask the question of whether or not a clear version could be produced.

Taking this on board, we developed a prototype clear version which Linda kindly set about testing, finding it to be the perfect product for use in toilet tanks within all their boats. Linda told us “all boaters that have trialled this new Clear Blue Bio have reported that it successfully cleans the toilet as well as getting rid of all bad odours, with the improved fragrance of the fluid also being very well received”.

Linda also highlighted that the improvement of adding citric acid to the formula prolongs the life of the seal in the toilet as it doesn’t scale up as quickly, making it rare that you need to do anything more to look after the toilet tank. Linda feels that one of the main benefits of Clear Blue Bio (and Blue Bio before it) is that it can also be used to clean the toilet bowl itself and this multi-purpose function is incredibly valuable when you are restricted as to which products you can use to clean your pride and joy.

Summing up, Linda told us “In a time where we are all more focussed on making sure out actions are environmentally friendly, Clear Blue Bio is the perfect product to use on all narrowboats and canal boats.

We know it contains no nasty chemicals so there are no concerns for our health either. Clear Blue Bio is a product we highly recommend for treating toilet tanks in all boats”.


Wessex Chemical Factors (WCF) is a family-run, specialist chemical company that has been trading since 1983

diesel bug – a layman’s guide

what is it? and how do we get rid of it?

what is it?


Diesel bugs are microbes that live at the interface between water and diesel fuel.

In some places it’s also known as diesel fungus or the diesel virus.

The presence of Diesel bug in your fuel tank can be a potential risk to your engine’s fuel system, can cause serious damage and eventually lead to engine failure.

If the fuel stored in your tank has been subject to variations in weather and temperature or your fuel has been stored for long periods without usage, then there is a considerable danger that your fuel may be contaminated.

contamination from water


The most common contaminant is WATER, usually building up from condensation.

Because biodiesel is hygroscopic (it attracts water molecules from atmospheric moisture). It is vital that the utmost care is taken to reduce, as far as possible, any contact which the fuel may have with water or water vapour.

Fuel containing any amount of water could seriously damage your equipment’s fuel injection system and would make it more prone to breaking down.

contamination from bacteria & the dreaded fuel bug

Sulphur free diesel containing biodiesel will also be more prone to bacterial contamination than normal mineral diesel or gas oil. This fuel has inherent bacteria and the presence of any water accelerates the growth of microbe colonies which are able to breed and multiply and will eventually completely plug and block a fuel system (see picture below).

This ‘bug’ will form a layer between the fuel and the water and as it breeds it produces waste which is usually  evident as black sludge and slimes or dark lumps. These eventually fall to the bottom of the tank and encourage further problems with the potential to cause severe damage through further blockage of fuel filters and increased corrosion.

symptoms, tests & cure


Your engine will stop, will let you restart, will carry on for a very few miles, then stop again.

Some diesel tanks have a tap at the bottom, which will allow you to run out a little diesel, or run off any water present. (The water sits at the bottom of your tank as it is heavier than diesel). An easy way to check for water contamination.

There are many products to help you test for diesel bug, and many that will go some way towards eliminating it. We would have to recommend our own products, such as our Diesel bug Testing Kit, & Diesel bug Killer. We would also recommend having a Fuel decontaminator fitted (removes any trace of moisture) and a fuel polishing system which would clean and polish your fuel while the engine is idle.

batteries – a brief encounter

batteries - a brief encounter

a guide to leisure batteries

size matters

When it comes to choosing leisure batteries for your narrowboat, you need to check the existing batteries for size and amperage rating. If you're living on the boat you will be reliant on the batteries, so it's very important to choose the right ones to power your everyday accessories. The physical size is crucial when choosing a battery. The bigger the battery, the bigger the ampere hour rating.

choose the right type of leisure battery

Narrowboats tend to use unsealed batteries as most designs have the batteries located near the engine bay. Excessive heat will cause evaporation and therefore unsealed batteries, even though most units are maintenance free, can be replenished with fluid to prolong their life. However, most leisure batteries are sealed units these days but are perfectly fine to use.

The most common leisure / deepcycle batteries used are listed below and they range from 110ah - 230ah.

There are 3 different grades of Leisure Batteries, Wet Flooded Lead Acid (the most common and cheapest), AGM Leisure Batteries and GEL Batteries. The pro's & Con's are described below. The physical size is crucial when choosing a battery. The bigger the battery, the more ampere hours (capacity).

standard wet flooded lead acid leisure batteries

Pros: These are the most common and popular type of leisure battery, sealed or unsealed. They are reasonably priced and can be used on most applications.

Cons: You should really only drain these batteries down to 40% of their capacity, so for example, if you had a 110ah battery, you're only using 60% of its capacity. They also drain quickly and take longer to recharge.

agm leisure batteries

Pros: AGM batteries have come down a lot in price over the last few years. They are becoming more & more popular for use on Camper Vans & Motorhomes which is understandable as AGM batteries are sealed, non spill-able and emit minimal gases.
They drain at a slower rate, so will last longer between recharges.
You can also use 80% of its capacity and they will charge almost 3 times faster than a standard flooded type battery.
AGM batteries have high cranking ability, so can power Caravan Movers and Outboard Motors. AGM batteries can also perform more cycles.

Cons: There aren't really any cons regarding these battery types. They used to be expensive and were limited in size variations. Now, there are many different sizes to choose from.

gel deep cyclic batteries

Pros: Gel Leisure Batteries are pure deep cyclic. These can be drained almost completely flat and still recover.

Suitable for deep discharge applications such as catering equipment, security cameras etc.

Cons: Sadly Gel batteries are very expensive, we only supply the best product brand of Gel which is Sonnenschein. The leisure Gel range we supply are not really suitable for starting applications but you can buy Gel batteries products with starting use.

Starter Batteries

We also supply engine starter batteries. Again starter batteries do vary in size and amplitude.

A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. In contrast, starter batteries (e.g. most automotive batteries) are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity.


At Advanced Batteries, we sell all the top leisure brands like Numax, Lucas, Varta, ABS Leisure and Trojan. You can choose from sealed and non sealed units and we can supply a range of flooded lead acid, absorbed glass mat (AGM) and even Gel type batteries. We are always ready with battery advice, so do get in touch.
