Come and meet the Promarine Team at this years go to event. This will be our second time attending the leading inland boat show and we look forward to meeting our new and existing customers.

Stuart visited www.colecraft.co.uk on Friday to view one of our in build widebeam boats.

Colecraft is a leading UK boatbuilder established since 1974 and a family run business.

As you can see the factory has 5 boats in build all of which will be completed and delivered before Christmas.

The quality of work and fit out is exemplary with maybe the only disappointment being delivery times for new boats are stretching into 2020.

Narrowboat in build with stage payments at various stages during the build, should be ready in time for Xmas.

Seacocks are present to shut off the flow of water from or to items of plumbing aboard the vessel.

There are three types of seacocks: the gate valve type, which is like the domestic plumbing type with a red wheel, which is turned clockwise to close; the ball valve type, which is preferred by many and has a lever to operate a chrome-plated bronze ball; and the traditional ‘Blakes’ type, which is complex in its construction and is comprised of a tapered peg, which is rotated by a lever inside a bronze housing.

Whatever type is used on your vessel, they should always be turned off when you leave the vessel, or, in the instance of the sink and sea toilet plumbing, they should be shut off whilst at sea.

However, the cockpit drain seacocks should be left on when leaving the boat to drain away rainwater.

Bronze is best as you do not need to wire seacock to an anode. This is because bronze does not contain very much zinc.  Brass is often known as commercial bronze as it is an alloy of copper, zinc and tin.
DZR is the most common material used for seacocks. DZR stands for Dezincification Resistant Brass but is actually a type of bronze.  So go for DZR or pure bronze.
Brass is too soft and contains too much zinc which leaches out of the metal.
Pure bronze is 88% copper 12% tin.
Pure brass is 90% copper 10% zinc.
Both are alloys so mixtures of the metal are used. Other derivatives of copper, tin, zinc and lead are gun metal and yellow metal.

The seacocks should be made of bronze and not brass, as is the case with domestic plumbing items that you get from a DIY shop.  Bronze is more resistant to electrolytic and galvanic corrosion, which is a major problem on boats.  When you buy new seacocks, you should ask the seller if they are bronze.  There are several different types of bronze, including Monel, but all include a mixture of copper, zinc and tin.  Brass is softer and the zinc can leach out away from the copper too easily.  You should check your seacocks every time that you visit your boat.  This should be done at least once a month, the seacock handle or lever should be turned from fully open to close a few times so that it does not seize up.  You should check for leaks.  The gate valve and ball valve types should not leak at all, but the Blakes type often drip a little, as they rely on a tapered peg with holes through it being pushed into a flange.

You should scrape the seacock every year to see if it has corroded.  A penknife or screwdriver should be used to scrape at the oxidised body of the valve.  If it is bright yellow when scraped, all is well, but if it is pinkish, it means that the zinc in the metal has started to leak away by electrolytic corrosion.  The seacock should be changed without delay if found to be corroded, as the metal will be brittle and might break off if the handle is turned.  Most sunken boats that I come across have come to grief because of a failed or leaking seacock.  This is a major weak point on any vessel.

Seacocks are mostly used below the waterline of the hull. They are screwed to a flange called a skin fitting, which is fitted to the hull to create a hole through which water can escape or enter the vessel.

Skin fittings are usually made of gunmetal, which is a mixture of copper, zinc, tin and chromium and is similar to bronze.

Skin fittings used below the waterline should not be made of nylon or other plastics, as they can become brittle and crack in time. Nylon is, however, used above the waterline for items such as bilge pump outlets and gas bottle locker drains.  Here are some examples of seacocks and skin fittings:

• Cockpit drains – usually two and found under the cockpit;
• Engine raw water coolant intake, sometimes with a strainer;
• Sea toilet effluent outlet;
• Sea toilet flushing water inlet;
• Galley sink and vanity basin drains.

Flexible hoses of reinforced PVC should be attached to hose flanges or the seacocks with two stainless steel ‘jubilee’-type hose clips.

Some seacocks are made of plastic.  They are fitted to some new European and American yachts and work well.

Forespar corrosion and electrolysis free lightweight plumbing units are an example.

Flexible hoses fitted to the seacocks should be of re-enforced PVC and not plain clear PVC.  Plain clear hoses crack with age.

Flexible hoses should be fitted to the seacock flanges by two hose clips at each hose end.

Best Canal Routes in the UK 2018

With the holidays quickly approaching it may be time to plan your next trip and with many beautiful sites in the UK, why not hire a boat?

Narrowboat Owner, Julie Cox, says: “If you are planning on hiring a boat, choose the area you want to visit and check the canal maps for what is involved.” With this in mind bwml.co.uk have put together a map of the best canal routes in the UK to help boaters discover the beauty of the country.

Grand Union Canal North of Milton Keynes

Included in the list, the Grand Union Canal starts in London and ends in Birmingham with multiple stops along the way. Perfect for exploring Oxford through to Aylesbury, it is the longest canal and is often referred to as the trunk of the system. This is because the waterway offers a diverse selection of traditional towns and villages and is ideal during the quiet autumn months; giving boaters’ more time to take in the stunning views.

Kennet & Avon Canal

Also mentioned, Kennet & Avon Canal is known for its spectacular landscapes and charming history. Linking Bristol all the way to Reading, the waterway takes boaters through some of the most beautiful scenery and memorable sites. With medieval buildings and Norman remains, the canal passes through many historic places and includes, the famous Avon Gorge, the Royal Crescent and lots of impressive structures designed by John Rennie.

Additionally, in recent years the canal has been redeveloped into a popular tourist destination for both boaters and families. Offering canoeing, fishing, walking and cycling, the area is filled with plenty of things to do and see.

The amount of people permanently living on houseboats such as narrowboats and barges has been steadily increasing in recent years. In fact, around a quarter of the boats you see on the UK waterways consist of the owner’s primary home. Many others are used as second homes with people sharing their time between on-board living and on-land living.

There are several reasons why more and more people are choosing this alternative way of life. The fact that living on a narrowboat in a city can be significantly cheaper than living in an ordinary home is chief among them.

As is to be expected of the capital, London is the most expensive place to live in the UK, but not if you live on a boat. In fact there are somewhere between 3,000 and 4,000 people using boats on the capital’s hundred miles of waterways, with around two thirds of those permanently docked at various marinas.

Continuous Cruising Lowers the Cost of Living Even More

UK boat owners who constantly travel around either a city’s waterways or up and down the country’s 2,000 or so miles of canal networks, can dock pretty much wherever they please for up to two weeks at a time. This ‘continuous cruising’ option makes living on a boat even cheaper as there is no charge for mooring, so long as you move on every couple of weeks.

With the lower annual cost of running a boat including covering a licence and basic insurance, it’s easy to see why boat living is becoming a more attractive proposition for people who are priced out of owning their own land-based homes, especially in a city like London where house prices have risen well over 80% over the last eight years or so.

In fact, the number of continuous cruisers in Britain has quadrupled in just seven years. In 2010, there were 413 continuous cruisers around the capital’s waterways alone, with that number heading way over 1,600 by the end of last year.

Quality of Life Also Cited as a Primary Reason for Boat Living

While the financial aspect is a huge one for many people who live on boats, it is not always the main reason. Last year the Financial Times published a feature on boat living and the reasons for living on a boat. While the money aspect was right up there in importance, the general way of living also featured highly.

“Waterside living is wonderful,” wrote the feature’s author, the boat dwelling Paul Miles.  “Rippling reflections of sunlight patterning your ceiling; feeding ducks from your window; diving off your front porch for a swim.”

With such testimony along with the obvious financial benefits, it’s certainly understandable why narrowboat living is on the rise.
